Show Answer
Answer: ((a))

A

Given:

Marks of students A, B, C, D and E from 2021 to 2025.

Calculation:

A: 75 + 90 + 96 + 92 + 86 = 439

B: 82 + 93 + 76 + 85 + 82 = 418

C: 75 + 85 + 65 + 66 + 73 = 364

D: 84 + 86 + 85 + 81 + 80 = 416

E: 74 + 79 + 85 + 82 + 83 = 403

Highest total marks = 439 (Student A)

∴ Student A has scored the maximum cumulative marks.

  4. ((d))

    2024

Show Answer
Answer: ((a))

2021

Given:

Marks of five students from 2021 to 2025.

Formula Used:

Average marks = Total marks of the year divided by Number of students

Calculation:

2021 total = 75 + 82 + 75 + 84 + 74 = 390 ⇒ Average = 390 / 5 = 78

2022 total = 90 + 93 + 85 + 86 + 79 = 433 ⇒ Average = 433 / 5 = 86.6

2023 total = 96 + 76 + 65 + 85 + 85 = 407 ⇒ Average = 407 / 5 = 81.4

2024 total = 92 + 85 + 66 + 81 + 82 = 406 ⇒ Average = 406 / 5 = 81.2

2025 total = 86 + 82 + 73 + 80 + 83 = 404 ⇒ Average = 404 / 5 = 80.8

Lowest average = 78 in the year 2021.

∴ 2021 witnessed the lowest average marks.

4

If we compare the cumulative combined marks of students A and B over the years with those of students C and D, then the marks scored by A and B together are more than those scored by C and D, by approximately what percent?

  1. ((a))

    77

  2. ((b))

     91

  3. ((c))

    15

  4. ((d))

    10

Show Answer
Answer: ((d))

10

Given:

Marks of students A, B, C and D for the years 2021–2025.

Formula Used:

Percent more = (Difference / Comparison value) × 100

Calculation:

(A + B) = (75 + 90 + 96 + 92 + 86) + (82 + 93 + 76 + 85 + 82) = 857

(C + D) = (75 + 85 + 65 + 66 + 73) + (84 + 86 + 85 + 81 + 80) = 780

Percent more = (857 − 780) / 780 × 100

⇒ 77 / 780 × 100 ≈ 9.87% ≈ 10%

∴ Marks scored by A and B together are approximately 10% more than those scored by C and D.

5

What was the approximate percentage increase of marks for student C from 2023 to 2025 ?

  1. ((a))

    7

  2. ((b))

    8

  3. ((c))

    12

  4. ((d))

    18

Show Answer
Answer: ((c))

12

Given:

Marks of student C in 2023 = 65

Marks of student C in 2025 = 73

Formula Used:

Percentage increase = (Increase / Original value) × 100

Calculation:

Increase = 73 − 65 = 8

Percentage increase = (8 / 65) × 100 ≈ 12.31% ≈ 12%

∴ The marks of student C increased by approximately 12% from 2023 to 2025.

6

Which aspect of security ensures that information is not altered by any unauthorised person ?

  1. ((a))

    Confidentiality

  2. ((b))

    Integrity

  3. ((c))

    Authentication

  4. ((d))

    Privacy

Show Answer
Answer: ((b))

Integrity

The correct answer is 'Integrity'

Key Points

  • Integrity:
  • Integrity in information security ensures that data remains accurate, consistent, and trustworthy throughout its lifecycle.
  • It is aimed at preventing any unauthorized modification, tampering, or alteration of information by unauthorized parties.
  • Measures used to ensure integrity include cryptographic hash functions, checksums, digital signatures, and access controls.
  • Integrity is critical in maintaining the reliability and authenticity of information, particularly in sensitive systems such as financial, medical, and governmental records.
  • Ensuring integrity safeguards against threats such as data breaches, unauthorized changes, and accidental corruption.

Additional Information

  • Confidentiality:
  • Confidentiality focuses on ensuring that sensitive information is accessed only by authorized individuals and is protected from unauthorized disclosure.
  • It is enforced through techniques such as encryption, access controls, and data masking.
  • While confidentiality protects information from being viewed by unauthorized users, it does not ensure that the information has not been altered or tampered with, which is the focus of integrity.
  • Authentication:
  • Authentication is the process of verifying the identity of a user, system, or entity before granting access to resources or information.
  • It is achieved through mechanisms like passwords, biometrics, or multi-factor authentication.
  • Authentication ensures that only legitimate users can access the system but does not address whether the data has been altered or modified.
  • Privacy:
  • Privacy refers to the right of individuals to control how their personal information is collected, used, and shared.
  • Privacy is concerned with protecting personal data from misuse or unauthorized access, ensuring compliance with laws and regulations.
  • It is distinct from integrity, as it focuses on the ethical and legal handling of personal information rather than maintaining the accuracy and consistency of data.

Important Points

  • Integrity is one of the three core principles of the CIA triad (Confidentiality, Integrity, Availability), which forms the foundation of information security.
  • It is essential for businesses and organizations to implement robust measures to protect data integrity, especially in critical sectors like finance, healthcare, and defense.
  • Data integrity violations can result in severe consequences, including financial loss, reputational damage, and legal liabilities.
  • Ensuring integrity also involves regular monitoring, auditing, and employing secure communication protocols to detect and prevent unauthorized modifications.

    Considering learners as sense makers who construct knowledge.

  4. ((d))

    Giving study materials to learners to recall the contents proficiently.

Show Answer
Answer: ((d))

Giving study materials to learners to recall the contents proficiently.

The correct answer is - Giving study materials to learners to recall the contents proficiently

Key Points

  • Constructivist teaching emphasizes active learning and knowledge construction.
  • A constructivist teacher focuses on engaging learners in active participation, rather than encouraging rote memorization.
  • Providing study materials solely for the purpose of recalling content does not align with the constructivist approach.
  • Constructivist teaching encourages learners to connect new knowledge with their existing understanding.
  • Sense making is a core aspect of constructivist teaching.
  • Constructivist teachers view learners as active constructors of knowledge, not passive receivers.
  • Encouraging memorization contradicts the idea of enabling learners to make sense of the learning material.

Additional Information

  • Principles of constructivist teaching:
  • Encourages learners to build their own understanding through active exploration.
  • Promotes collaborative learning where learners can share and discuss ideas.
  • Focuses on real-world applications to make learning meaningful and relevant.
  • Common strategies used by constructivist teachers:
  • Problem-based learning: Encouraging learners to solve real-life problems.
  • Inquiry-based learning: Motivating learners to ask questions and seek answers.
  • Interactive discussions: Promoting dialogue and reflection to deepen understanding.

Identify the correct mathematical statement(s):

A. If the cost price of 10 articles is equal to selling price of 9 articles, then profit is 10%.

B. 423+312123=1324\frac{2}{3} + 3\frac{1}{2} - 1\frac{2}{3} = \frac{13}{2}

C. If xy=275, then yxy+x=7773\text{If } \frac{x}{y} = \frac{2}{75}, \text{ then } \frac{y - x}{y + x} = \frac{77}{73}

D. 10.04 is equal to 25\frac{1}{0.04} \text{ is equal to } 25

Choose the correct answer from the options given below :

  1. ((a))

    B and D Only

  2. ((b))

    A and B Only

  3. ((c))

    B, C and D Only

  4. ((d))

    D Only

Show Answer
Answer: ((a))

B and D Only

Given:

A. If the cost price of 10 articles is equal to selling price of 9 articles, then profit is 10%.

B. 4(2)/3 + 3(1)/2 - 1(2)/3 = 13/2

C. If x/y = 2/75, then (y - x)/(y + x) = 77/73

D. 1/0.04 is equal to 25

Formula used:

Profit = (Selling Price - Cost Price) / Cost Price × 100

Arithmetic operations for B

Division for D

Calculations:

For A:

Cost price of 10 articles = Selling price of 9 articles

⇒ Let cost price of 1 article = ₹1

⇒ Cost price of 10 articles = ₹10

⇒ Selling price of 9 articles = ₹10

⇒ Selling price of 1 article = ₹10/9

⇒ Profit = (10/9 - 1)/1 × 100

⇒ Profit = 1/9 × 100 = 11.11%

∴ Statement A is incorrect.

For B:

4(2)/3 + 3(1)/2 - 1(2)/3

⇒ LCM of 3 and 2 = 6

⇒ (8/3 = 16/6), (3/2 = 9/6), (2/3 = 4/6)

⇒ 16/6 + 9/6 - 4/6

⇒ (16 + 9 - 4)/6 = 21/6

⇒ 21/6 = 13/2

∴ Statement B is correct.

For C:

x/y = 2/75

⇒ y = 75, x = 2

⇒ (y - x)/(y + x) = (75 - 2)/(75 + 2)

⇒ 73/77

∴ Statement C is incorrect.

For D:

1/0.04

⇒ 1 ÷ 0.04

⇒ 1 ÷ (4/100)

⇒ 100/4 = 25

∴ Statement D is correct.

∴ The correct answer is option (1): B and D Only.

Which of the following are true?
A. Some valid arguments contain false premises and a false conclusion.
B. An argument can be invalid even if all the premises are true and the conclusion is true as well.
C. When an argument is valid and all of its premises are true, it is called sound argument.
D. The truth or falsity of the premises in an argument does not determine the soundness of the argument.
Choose the correct answer from the options given below :

  1. ((a))

    A, B and C Only

  2. ((b))

    A and B Only

  3. ((c))

    A, C and D Only

  4. ((d))

    B, C and D Only

Show Answer
Answer: ((a))

A, B and C Only

The Correct answer is: 1) A, B and C Only

Key Points

  • Statement A: Some valid arguments contain false premises and a false conclusion:
  • This statement is correct.
  • A valid argument is one where the conclusion logically follows from the premises. However, the truth of the premises and the conclusion is not a requirement for validity.
  • For example, consider this argument:
  • Premise 1: If pigs can fly, then the moon is made of cheese.
  • Premise 2: Pigs can fly.
  • Conclusion: The moon is made of cheese.
  • Here, the premises and conclusion are false, but the argument is valid because the conclusion logically follows from the premises.
  • Statement B: An argument can be invalid even if all the premises are true and the conclusion is true as well:
  • This statement is correct.
  • For an argument to be valid, the conclusion must follow logically from the premises. However, it is possible for an argument to have true premises and a true conclusion, yet still be invalid if the logical connection between the premises and conclusion is missing.
  • For example:
  • Premise: All cats are animals.
  • Premise: Dogs are animals.
  • Conclusion: All cats are dogs.
  • Here, the premises and conclusion are true, but the argument is invalid because the conclusion does not logically follow from the premises.
  • Statement C: When an argument is valid and all of its premises are true, it is called a sound argument:
  • This statement is correct.
  • A sound argument is defined as a valid argument with all true premises. In such cases, the conclusion must also be true.
  • For example:
  • Premise: All mammals are animals.
  • Premise: All dogs are mammals.
  • Conclusion: All dogs are animals.
  • This argument is valid (logical structure) and has all true premises, so it is a sound argument.
  • Statement D: The truth or falsity of the premises in an argument does not determine the soundness of the argument:
  • This statement is incorrect.
  • The soundness of an argument is directly dependent on the truth of its premises. An argument is sound only if:
  • It is valid (logical structure), and
  • All its premises are true.
  • For example:
  • Premise: All birds can fly.
  • Premise: Penguins are birds.
  • Conclusion: Penguins can fly.
  • The argument is valid, but the premise "All birds can fly" is false, making the argument unsound.

Additional Information

  • Key Definitions:
  • Validity: An argument is valid if the conclusion logically follows from the premises, regardless of their truth or falsity.
  • Soundness: An argument is sound if it is valid and all its premises are true.
  • Examples of Valid and Invalid Arguments:
  • Valid but Unsound Argument:
  • Premise: If it rains, the ground will be wet.
  • Premise: It rains.
  • Conclusion: The ground is wet.
  • Logical structure is valid, but if the first premise is false (e.g., rain doesn’t reach the ground due to a cover), the argument is unsound.
  • Invalid Argument:
  • Premise: All cats are animals.
  • Premise: All dogs are animals.
  • Conclusion: All cats are dogs.
  • Logical structure is invalid, even though the premises and conclusion are true.

Which of the following are true?

A. In Equivocation fallacy, two or more meanings of the same word create confusion.

B. Amphiboly is not a fallacy of Ambiguity.

C. Accent is a fallacy that moves in a circle.

D. Composition and division are fallacies of ambiguity.

Choose the correct answer from the options given below :

  2. ((b))

    B and C Only

  3. ((c))

    A and B Only

  4. ((d))

    A, B, C and D

Show Answer
Answer: ((a))

A and D Only

The Correct answer is: A and D Only

Key Points

  • Statement A: In Equivocation fallacy, two or more meanings of the same word create confusion:
  • This statement is correct.
  • The Equivocation fallacy occurs when a word or phrase is used with multiple meanings in the same argument, leading to confusion or misinterpretation.
  • For example, the term "light" could mean "not heavy" or "bright." If someone uses the term "light" ambiguously within an argument, it creates a logical fallacy.
  • This type of ambiguity undermines the validity of arguments and is a common fallacy of ambiguity.
  • Statement B: Amphiboly is not a fallacy of Ambiguity:
  • This statement is incorrect.
  • Amphiboly is indeed a fallacy of ambiguity. It arises when a sentence or phrase has an ambiguous grammatical structure, leading to misinterpretation.
  • For example, "The professor said on Monday he would give a lecture" could mean the professor made the statement on Monday or that the lecture will occur on Monday.
  • Because Amphiboly involves ambiguity, the statement claiming it is not a fallacy of ambiguity is false.
  • Statement C: Accent is a fallacy that moves in a circle:
  • This statement is incorrect.
  • The fallacy of Accent occurs when emphasis is placed on a particular word or phrase in a way that changes the intended meaning of a statement.
  • It does not involve circular reasoning; rather, it exploits ambiguity through emphasis or tone.
  • For example, "I never said she stole the money" can have different meanings depending on which word is emphasized.
  • Statement D: Composition and division are fallacies of ambiguity:
  • This statement is correct.
  • The fallacies of composition and division arise from errors in reasoning about parts and wholes.
  • The fallacy of composition occurs when someone assumes that what is true of the parts must be true of the whole. For example, "Each player on the team is skilled, so the team must be skilled."
  • The fallacy of division occurs when someone assumes that what is true of the whole must be true of the parts. For example, "The team is skilled, so every player must be skilled."
  • Both are categorized as fallacies of ambiguity because they rely on unclear reasoning about parts and wholes.

The difference between consecutive letters is +3, except for L (a reset).

⇒ Missing letter = S (83) + 3 = V (86).

Finally, analyze the third letters:

O (79), R (82), U (85), ?, O (79)

The difference between consecutive letters is +3, except for O (a reset).

⇒ Missing letter = U (85) + 3 = X (88).

⇒ Missing term = LVX.

∴ The correct answer is option (3).

  4. ((d))

    E, D, A, С, В

Show Answer
Answer: ((b))

C, B, E, D, A

The correct answer is: 2 - C, B, E, D, A

In Indian philosophy and yogic traditions, the concept of personality or the self is explained through the "Panchakosha" (five sheaths). These sheaths represent layers of existence, from the most tangible and physical to the most subtle and spiritual. Understanding the Panchakosha framework helps in realizing the ultimate truth of the self, transcending all layers to attain self-realization or liberation.

Key Points

Sheaths of Personality in Order:

  • Annamaya Kosh (C) - Physical Sheath:
  • This is the outermost and grossest layer of personality.
  • It represents the physical body, which is composed of food (Anna) and nourished by it.
  • It includes the bones, muscles, tissues, and organs—the tangible aspects of our being.
  • When we focus on physical health and fitness, we are primarily addressing this sheath.
  • Pranamaya Kosh (B) - Vital Sheath:
  • This layer governs the life force or vital energy (Prana) that sustains the physical body.
  • It includes the breath, circulation of blood, and other vital functions.
  • Activities like pranayama (breathing exercises) and energy management work on this sheath.
  • It acts as a bridge between the physical and mental layers.

  4. ((d))

    D < E < B < A < C

Show Answer
Answer: ((c))

D < B < A < E < C

Given:

Fractions:

A = 5/8

B = 7/12

C = 13/16

D = 16/29

E = 3/4

Formula used:

To arrange fractions in ascending order, convert them to a common denominator or compare their decimal values.

Calculation:

Converting to decimal values for comparison:

A = 5 ÷ 8 = 0.625

B = 7 ÷ 12 = 0.5833

C = 13 ÷ 16 = 0.8125

D = 16 ÷ 29 ≈ 0.5517

E = 3 ÷ 4 = 0.75

Arranging in ascending order:

D (0.5517) < B (0.5833) < A (0.625) < E (0.75) < C (0.8125)

∴ The correct order is D < B < A < E < C

  • Example: Solifluction occurs in high-altitude regions like the Himalayas and Andes.
  • Drought and Famine:
  • Drought: A prolonged period of abnormally low rainfall, leading to a shortage of water, is termed a drought.
  • Famine: Drought often leads to famine, which is a widespread scarcity of food caused by disrupted agricultural activities, lack of water, and economic challenges.
  • Example: The Ethiopian famine of 1983–1985 was partly caused by severe drought conditions.
  • Earthquakes and Shock Waves:
  • Earthquake: A sudden and violent shaking of the ground, typically caused by the movement of tectonic plates, is called an earthquake.
  • Shock Waves: These are seismic waves generated during an earthquake. They propagate through the Earth and cause destruction on the surface.

Three years ago, the average age of a family of 5 members was 17 years. A baby was born, but the average age of the family is still the same today. The present age of the baby is:

  1. ((a))

    3 years

  2. ((b))

    4 years

  3. ((c))

    2 years

  4. ((d))

    5 years

Show Answer
Answer: ((c))

2 years

Given:

Three years ago, average age of family (5 members) = 17 years

Present average age of family (6 members) = 17 years

Baby born after 3 years

Formula used:

Sum of ages = Average × Number of members

Calculation:

Three years ago, total age of 5 members = 17 × 5 = 85 years

Present total age of the original 5 members = 85 + (3 × 5) = 100 years

Present total age of 6 members = 17 × 6 = 102 years

⇒ Age of the baby = 102 - 100 = 2 years

∴ The correct answer is option (3).

  1. ((a))

    Transmissional Perspective

  2. ((b))

    Publicity Perspective

  3. ((c))

    Ritual Perspective

  4. ((d))

    Critical Perspective

Show Answer
Answer: ((c))

Ritual Perspective

The correct answer is 'Ritual Perspective'

Key Points

  • Ritual Perspective:
  • The ritual perspective views mass communication as a cultural process that represents shared beliefs and values within a society.
  • It emphasizes how communication helps produce, maintain, repair, and transform the reality of the social world.
  • This perspective focuses less on the transmission of information and more on the symbolic and cultural meanings conveyed through communication.
  • It highlights the role of media in maintaining cultural traditions, fostering community identity, and reinforcing societal norms.
  • Mass communication is seen as a ritualistic act that binds people together by shaping collective experiences and shared understanding.
  • For instance, watching a televised national event or reading a newspaper can contribute to the shared reality and cultural identity of a community.

Additional Information

  • Transmissional Perspective:
  • This perspective views mass communication primarily as a process of transmitting information from a sender to a receiver.
  • It emphasizes the technical aspects of communication, such as the encoding, transmission, and decoding of messages.
  • Unlike the ritual perspective, the transmissional perspective focuses on the efficiency and accuracy of information delivery rather than its cultural or symbolic significance.
  • It is often associated with linear communication models like Shannon and Weaver's communication model.
  • This perspective is more suited to contexts where the goal is to convey specific data or knowledge, rather than fostering shared cultural values.
  • Publicity Perspective:
  • The publicity perspective focuses on mass communication as a tool for attention and visibility rather than understanding or shared beliefs.
  • It highlights how communication is used to attract public attention, promote ideas, or market products and services.
  • This perspective is common in advertising, marketing, and public relations, where the primary goal is to create awareness or influence perceptions.
  • Unlike the ritual perspective, it does not emphasize the symbolic or cultural role of communication in shaping societal norms or shared realities.
  • Critical Perspective:
  • The critical perspective examines mass communication through the lens of power, ideology, and social structures.
  • It focuses on how media systems can perpetuate inequalities, manipulate audiences, and serve the interests of dominant groups or ideologies.
  • This perspective often critiques the role of media in reinforcing hegemonic norms and suppressing alternative voices.
  • While it provides valuable insights into the societal impacts of communication, it differs from the ritual perspective, which centers on shared cultural practices and meanings rather than power dynamics.

Important Points

  • The ritual perspective is closely associated with scholars like James W. Carey, who argued that communication is more about sustaining cultural practices than merely transmitting information.
  • This approach challenges traditional views of communication as a mechanical process and instead highlights its role in creating and maintaining shared realities.
  • It underscores the importance of understanding media as a cultural force that influences societal norms, identities, and values.
  • By focusing on the symbolic and communal aspects of communication, the ritual perspective provides a deeper understanding of how media shapes the social fabric.

  1. ((a))

    Asiddha

  2. ((b))

    Satpratipakşa

  3. ((c))

    Savyabhicāra

  4. ((d))

    Viruddha

Show Answer
Answer: ((c))

Savyabhicāra

The correct answer is 'Savyabhicāra'

Key Points

  • Explanation of Savyabhicāra:
  • Savyabhicāra, also referred to as the fallacy of irregularity or deviation, occurs when the middle term (hetu) in a syllogism does not necessarily lead to the conclusion or is not invariably connected to the major term.
  • In this case, the argument is as follows:
  • All bipeds are rational (major premise).
  • Swans are bipeds (minor premise).
  • Therefore, swans are rational (conclusion).
  • Here, the middle term "biped" does not always lead to the conclusion that all bipeds are rational. For example, some bipeds (like certain animals or humans in irrational states) may not be rational. Hence, the reasoning is flawed due to Savyabhicāra.
  • This fallacy arises because the middle term (biped) is not universally applicable to guarantee the conclusion (being rational).

Additional Information

  • Asiddha (Unproven):
  • Asiddha refers to the fallacy where the middle term (hetu) is unproven or not established in the minor term.
  • In this case, "Swans are bipeds" is a valid statement and is well-established. Hence, the fallacy of Asiddha does not apply here.
  • Satpratipakṣa (Counterbalanced Middle Term):
  • This fallacy arises when the middle term is contradicted by an equally valid counterexample.
  • For example, if an argument states, "Sound is eternal because it is audible," a counterexample could be provided that sound is non-eternal because it is produced. In the given argument, no such counterexample exists for "Swans are bipeds," so this fallacy is not applicable.
  • Viruddha (Contradictory Middle Term):
  • Viruddha occurs when the middle term (hetu) leads to a conclusion that contradicts the proposition.
  • In this case, the middle term "biped" does not lead to a contradictory conclusion about rationality. Thus, Viruddha is not applicable here.

Important Points

  • The fallacy of Savyabhicāra highlights the importance of a strict and necessary connection between the middle term and the conclusion in logical reasoning.
  • In classical Indian logic, the evaluation of valid reasoning (anumāna) relies on ensuring that the middle term (hetu) is free from such fallacies to avoid erroneous conclusions.
  • Understanding different types of fallacies (hetvābhāsas) is crucial for refining logical arguments and ensuring sound reasoning in philosophical discourse.

The Blue-Baby Syndrome is caused by the contamination of ______ in drinking water.

  1. ((a))

    Mercury

  2. ((b))

    Lead

  3. ((c))

    Nitrate

  4. ((d))

    Arsenic

Show Answer
Answer: ((c))

Nitrate

The correct answer is 'Nitrate'

Key Points

  • Blue-Baby Syndrome:
  • Blue-Baby Syndrome, also known as methemoglobinemia, is a condition that primarily affects infants and causes their skin to turn blue due to a lack of oxygen in the blood.
  • The condition is often caused by high levels of nitrate contamination in drinking water, which is converted into nitrite in the body.
  • Nitrites interfere with the blood's ability to carry oxygen by transforming hemoglobin into methemoglobin, which cannot effectively bind oxygen.
  • This condition is most dangerous for infants under six months old because their digestive systems are more susceptible to converting nitrates into nitrites.
  • Sources of Nitrate Contamination:
  • Nitrate contamination in water is usually caused by agricultural runoff, including fertilizers, animal waste, and septic system leakage.
  • Excessive use of nitrogen-based fertilizers in farming can lead to leaching of nitrates into groundwater.
  • Industrial discharge and improper waste disposal can also contribute to nitrate pollution in water sources.

Additional Information

  • Mercury:
  • Mercury contamination in drinking water can lead to neurological and developmental issues, especially in children, but it does not cause Blue-Baby Syndrome.
  • It is primarily associated with mercury poisoning, which affects the nervous system and can lead to symptoms such as tremors, memory loss, and cognitive impairments.
  • Lead:
  • Lead contamination in water is a significant public health concern and can result in developmental delays, learning disabilities, and other long-term health issues.
  • However, lead exposure is not related to the development of Blue-Baby Syndrome.
  • Arsenic:
  • Arsenic in drinking water is toxic and is linked to various health issues, including skin lesions, cancer, cardiovascular diseases, and neurological disorders.
  • While dangerous, arsenic contamination does not cause Blue-Baby Syndrome.

Important Points

  • The World Health Organization (WHO) and other health authorities recommend that nitrate levels in drinking water should not exceed 50 mg/L to minimize the risk of Blue-Baby Syndrome.
  • Boiling water does not reduce nitrate levels; in fact, it can concentrate the nitrates further as water evaporates.
  • Prevention strategies include proper management of agricultural practices, appropriate waste disposal, and regular monitoring of water sources for nitrate contamination.
  • Infants should not be fed formula made with nitrate-contaminated water to avoid the risk of this syndrome.

Key Points

  • Assertion (A): People who are shown Television news edited to draw attention to a particular problem, assign greater importance to that problem.
  • This statement is correct.
  • When television news repeatedly highlights or edits content to emphasize a specific issue, viewers tend to perceive that issue as more significant.
  • This occurs because media framing and selective emphasis influence public perception.
  • Experimental studies in mass communication have shown that audiences exposed to emphasized news topics rank those issues as more important compared to less-highlighted topics.
  • Reason (R): People learn how much importance to attach to an issue or topic from the emphasis the mass media places upon it.
  • This statement is correct.
  • This idea is based on the Agenda-Setting Theory of mass communication.
  • According to this theory, the media may not tell people what to think, but it tells them what to think about.
  • The frequency, placement, and prominence given to issues in mass media shape public priorities and perceptions of importance.
  • Evaluation of the Relationship Between (A) and (R):
  • The assertion describes a practical outcome observed in audiences exposed to emphasized television news.
  • The reason provides the theoretical explanation behind this outcome through agenda-setting.
  • The emphasis placed by mass media directly influences how audiences rank issues in terms of importance.
  • Therefore, the reason correctly explains why people assign greater importance to problems highlighted in television news.
  • Hence, the correct answer is Option 1: Both (A) and (R) are correct and (R) is the correct explanation of (A).

Additional Information

  • Agenda-Setting Theory: Proposed by McCombs and Shaw (1972), this theory explains how media coverage influences public perception of issue importance.
  • Media Framing: Apart from agenda-setting, framing theory explains how the presentation and angle of news stories can further influence interpretation and opinion.
  • Impact on Democracy: Agenda-setting plays a crucial role in political communication, public opinion formation, and electoral behavior.

Given below are two statements one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): Increase in average sea surface temperature will contribute towards enhancement of atmospheric CO2 concentration.

Reason (R): Increase in sea surface temperature increases the solubility of CO2 in ocean water.

In the light of the above statements, choose the most appropriate answer from the options given below:

  1. ((a))

    Both (A) and (R) are correct and (R) is the correct explanation of (A)

  2. ((b))

  3. ((c))

    (A) is correct but (R) is not correct

  4. ((d))

    (A) is not correct but (R) is correct

Show Answer
Answer: ((c))

(A) is correct but (R) is not correct

The correct option is '(A) is correct but (R) is not correct'.

Key Points

  • Assertion A: Increase in average sea surface temperature will contribute towards enhancement of atmospheric CO2 concentration.
  • This statement is correct.
  • Scientific Basis: Oceans act as significant carbon sinks, absorbing vast amounts of CO2 from the atmosphere. However, when sea surface temperatures rise, the capacity of oceans to retain CO2 diminishes due to reduced solubility of CO2 in warmer water.
  • Impact on the Atmosphere: As the ocean's ability to absorb CO2 decreases, more CO2 remains in the atmosphere, leading to an increase in atmospheric CO2 concentration.
  • Reason R: Increase in sea surface temperature increases the solubility of CO2 in ocean water.
  • This statement is incorrect.
  • Contradictory Evidence: The solubility of CO2 in water decreases with an increase in temperature. When water is warmer, it holds less gas, including CO2. This is a well-established principle in physical chemistry.
  • Misinterpretation: The reason provided contradicts the scientific understanding of CO2 solubility in ocean water. Higher temperatures actually reduce the ocean's ability to absorb CO2.
  • Evaluation of the Relationship Between A and R:
  • While the assertion (A) is true, the reason (R) provided is incorrect.
  • Increase in sea surface temperature leads to reduced solubility of CO2 in ocean water, contrary to the claim in (R). Thus, (R) does not support or explain (A).

Additional Information

  • Oceans as Carbon Sinks: Oceans play a crucial role in regulating atmospheric CO2 levels by absorbing CO2. This process is influenced by various factors, including temperature, salinity, and pressure.
  • Temperature and Solubility: The solubility of gases, including CO2, in water decreases with increasing temperature. This is why warm oceans absorb less CO2 compared to colder regions.
  • Climate Change Implications: Rising sea temperatures due to global warming can significantly impact the Earth's carbon cycle, contributing to higher atmospheric CO2 levels and amplifying the greenhouse effect.

  4. ((d))

    Oxygen and butane

Show Answer
Answer: ((b))

Methane and hydrogen

The correct answer is 'Methane and hydrogen'

Key Points

  • Biogas:
  • Biogas is a renewable energy source produced through the anaerobic digestion of organic matter such as agricultural waste, manure, municipal waste, plant material, and sewage.
  • The primary components of biogas are methane (CH4) and hydrogen (H2). Methane typically makes up 50-70% of the biogas composition, while hydrogen is present in smaller amounts.
  • Methane is the main energy-yielding component of biogas and is highly flammable, making biogas suitable for use as fuel in heating, cooking, and electricity generation.
  • Hydrogen present in biogas contributes to its overall energy content and can be extracted for industrial applications.
  • Biogas production is an environmentally friendly process that reduces greenhouse gas emissions, mitigates waste, and provides a sustainable energy alternative.

Additional Information

  • Incorrect Options:
  • Methane and ethane:
  • Ethane (C2H6) is not a typical component of biogas. It is found in natural gas but does not form during the anaerobic digestion process that produces biogas.
  • While methane is a major part of biogas, ethane does not contribute to its formation or energy content.
  • Ethanol and methane:
  • Ethanol (C2H5OH) is an alcohol, not a gaseous component of biogas. It is produced through fermentation processes but is unrelated to biogas production.
  • Biogas primarily consists of methane and does not contain ethanol as part of its composition.
  • Oxygen and butane:
  • Biogas is produced in an anaerobic environment, meaning oxygen is absent during its creation. Oxygen does not form part of the biogas composition.
  • Butane (C4H10) is a hydrocarbon found in liquefied petroleum gas (LPG), not biogas. It does not occur naturally in biogas production.
  • Importance of Biogas:
  • Biogas serves as a sustainable energy source, reducing reliance on fossil fuels.
  • It helps in waste management by utilizing organic waste materials.
  • Biogas production reduces methane emissions from decomposing waste, contributing to climate change mitigation.
  • The by-product of biogas production, known as digestate, is a nutrient-rich material that can be used as fertilizer.

Important Points

  • Biogas plants are widely used in rural and urban areas to provide clean and sustainable energy.
  • The biogas production process is an example of a circular economy, utilizing waste to generate energy and valuable by-products.
  • Countries around the world are investing in biogas technology to promote renewable energy and reduce carbon footprints.
  • Biogas can also be upgraded to biomethane, which is a purified form of methane suitable for use in natural gas pipelines and vehicles.

In programming, the process of creating and running a program involves multiple stages that must follow a logical sequence to ensure the program functions as expected. These stages include editing, compilation, linking, and execution. Understanding these stages is crucial for programmers to develop and debug software effectively.

Key Points

Logical Sequence of Programming Process:

  • Editing (B):
  • This is the first stage, where the programmer writes the source code using a text editor or an Integrated Development Environment (IDE).
  • The source code is written in a programming language like C, Python, Java, etc.
  • Editing involves creating, modifying, and saving the code files.
  • Errors in syntax or logic during this stage can be rectified before proceeding to the next step.
  • Compilation (A):
  • After editing, the source code is passed through a compiler.
  • The compiler converts the human-readable source code into machine-readable object code.
  • This step checks for syntax errors and generates error messages if issues are found.
  • A successful compilation results in an object file, which is a lower-level representation of the program.
  • Linking (C):
  • The object file generated during compilation is incomplete as it may rely on external libraries or other modules.
  • The linker combines the object file with necessary libraries and modules to create an executable file.
  • This stage resolves references to external functions or variables and ensures the program is ready for execution.
  • If the linking process fails, errors such as undefined references are reported.
  • Execution (D):
  • Once the executable file is created, the program can be run or executed.
  • During execution, the program performs the tasks as coded, producing the desired output or interacting with the user.
  • Runtime errors, if any, may occur during this stage, which must be debugged and fixed.
  • This is the final stage where the program’s functionality is verified.

Additional Information

  • The process of programming is iterative; programmers often return to the editing stage to make corrections or improvements based on errors or feedback encountered during compilation or execution.
  • Modern IDEs streamline this process by integrating editing, compilation, linking, and execution into a single interface, making the workflow more efficient.
  • Debugging tools are commonly used during the execution stage to identify and resolve runtime errors.
  • Understanding the dependencies between libraries and modules is critical during the linking stage to avoid errors like missing references.
  • Effective programming requires attention to detail at each stage to ensure the final executable is error-free and achieves its intended purpose.

The question pertains to the concept of bioaccumulation and biomagnification in an aquatic ecosystem, particularly focusing on how a pesticide contaminates a lake and accumulates in organisms at different trophic levels. These processes are critical in understanding the increasing concentration of harmful substances as they move up the food chain.

Key Points

  • Bioaccumulation:
  • Refers to the process by which toxic substances, such as pesticides, accumulate in an organism over time.
  • The pesticide enters the lake water through runoff, industrial discharge, or agricultural practices.
  • In organisms, such substances are absorbed faster than they are broken down or excreted.
  • Biomagnification:
  • Refers to the increasing concentration of toxins as they move up the food chain.
  • Organisms at higher trophic levels accumulate toxins from their food, leading to greater concentrations in predators compared to prey.
  • Order of Accumulation in Lake Ecosystem:
  • Water (A):
  • Pesticide concentration is the lowest in water because the substance is diluted over a large volume.
  • However, this serves as the entry point for pesticides into the food chain.
  • Phytoplankton (C):
  • These are microscopic algae that form the base of the aquatic food chain.
  • Phytoplankton absorb pesticides from water directly and accumulate toxins at a higher concentration than water.
  • Zooplankton (B):
  • Zooplankton feed on phytoplankton and accumulate pesticides present in their prey.
  • The concentration of pesticides in zooplankton is higher than in phytoplankton due to biomagnification.
  • Fish (D):
  • Fish consume zooplankton and other small organisms, further concentrating the pesticide in their bodies.
  • Their larger size and higher trophic level result in higher pesticide levels compared to zooplankton.
  • Birds (E):
  • Birds, such as fish-eating species, are at the top of the food chain in this ecosystem.
  • They accumulate the highest concentration of pesticides due to biomagnification, which poses serious health risks to them, such as reproductive issues and mortality.

Additional Information

  • Pesticides, such as DDT, are persistent organic pollutants (POPs). They do not easily break down in the environment and thus remain in the ecosystem for long periods.
  • The process of biomagnification can lead to severe ecological consequences, such as the thinning of bird eggshells and population decline in certain species.
  • To combat these issues, many countries have banned or restricted the use of harmful pesticides like DDT.
  • Understanding the concepts of bioaccumulation and biomagnification is crucial for developing sustainable agricultural practices and protecting aquatic ecosystems.

Given below are two statements one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): An argument can never be valid, if all the premises are false and conclusion is false as well.

Reason (R): If an argument is valid and its premises are true, we may be certain that its conclusion is true also.

In the light of the above statements, choose the most appropriate answer from the options given below:

  1. ((a))

    Both (A) and (R) are correct and (R) is the correct explanation of (A)

  2. ((b))

    Both (A) and (R) are correct but (R) is not the correct explanation of (A)

  3. ((c))

    (A) is correct but (R) is not correct

  4. ((d))

    (A) is not correct but (R) is correct

Show Answer
Answer: ((d))

(A) is not correct but (R) is correct

The correct option is '(A) is not correct but (R) is correct'.

Key Points

  • Assertion (A): An argument can never be valid, if all the premises are false and the conclusion is false as well.
  • This statement is incorrect.
  • Validity of an Argument: Validity in logic is independent of the truth of the premises or the conclusion. An argument is valid if the conclusion logically follows from the premises, regardless of whether the premises or the conclusion are true or false. For example, if the premises "All cats are dogs" and "All dogs are fish" are false, but the conclusion "All cats are fish" logically follows from the premises, the argument is still valid.
  • Hence, it is possible for an argument with false premises and a false conclusion to be valid.
  • Reason (R): If an argument is valid and its premises are true, we may be certain that its conclusion is true also.
  • This statement is correct.
  • Logical Implication: A valid argument ensures that if the premises are true, the conclusion must also be true. This is the very definition of validity in logic. It guarantees that the truth of the premises leads to the truth of the conclusion.
  • Thus, Reason (R) accurately captures the concept of validity in logical arguments.
  • Evaluation of the Relationship Between A and R:
  • The assertion (A) is not correct, as it misunderstands the concept of validity in logic.
  • The reason (R), however, is correct and provides an accurate description of validity in logic.
  • There is no direct relationship between (A) and (R) because (R) does not explain or support the incorrect assertion (A).

Additional Information

  • Validity vs. Truth: Validity is a structural property of an argument and does not depend on the actual truth of the premises or the conclusion. Truth, on the other hand, is a property of individual statements (premises or conclusion).
  • Soundness: An argument is sound if it is both valid and all its premises are true. Soundness ensures that the conclusion is true as well.
  • Example of Validity: Consider the argument:
  • Premise 1: All unicorns are blue (false).
  • Premise 2: All blue things are magical (false).
  • Conclusion: All unicorns are magical (false).

Even though all premises and the conclusion are false, the argument is valid because the conclusion logically follows from the premises.

Answer: ((a))

Chronemics

The correct answer is 'Chronemics'

Key Points

  • Chronemics:
  • Chronemics is the study of how humans perceive and use time as a form of communication.
  • It explores how time influences our interactions, behaviors, and communication styles in different cultural, social, and professional contexts.
  • Chronemics helps us understand cultural variations in time perception, such as punctuality, scheduling, and the significance of past, present, and future orientations.
  • It also examines concepts like monochronic (doing one task at a time) and polychronic (multitasking and prioritizing relationships over rigid schedules) cultures.
  • Effective use of chronemics can shape impressions, relationships, and the efficiency of communication in both personal and professional domains.

Additional Information

  • Polychronic:
  • Polychronic refers to a cultural orientation where individuals prefer multitasking and prioritize relationships over strict adherence to schedules.
  • It is a concept related to the use of time but does not encompass the broader communicative aspects of time studied in chronemics.
  • Examples of polychronic cultures include many Latin American and Mediterranean societies.
  • Monochronic:
  • Monochronic describes cultures that value doing one task at a time, strict scheduling, and punctuality.
  • This concept is a subset of time-related studies but does not represent the broader field of chronemics.
  • Monochronic cultures are often found in countries like the United States, Germany, and Switzerland.
  • Haptics:
  • Haptics is the study of touch as a form of communication, such as handshakes, hugs, and other physical gestures.
  • While it is an important aspect of nonverbal communication, it is unrelated to the study of time.
  • Haptics focuses on tactile interactions rather than time-based communication.

Important Points

  • Chronemics plays a vital role in understanding intercultural communication, as different cultures perceive and value time differently.
  • For instance, Western cultures often emphasize punctuality and strict schedules, while many Eastern cultures focus on flexibility and relational harmony.
  • Chronemics also affects workplace communication, where time management and deadlines influence productivity and team dynamics.
  • Understanding chronemics can aid in conflict resolution, effective communication, and fostering mutual respect in multicultural environments.

Which among the following is not true with regards to the UGC guidelines (2022) for pursuing two academic programmes simultaneously?

  1. ((a))

    Two full time academic programmes in physical mode are allowed if the class timings for one programme do not overlap with the class timings of the other programme.

  2. ((b))

    Two academic programmes, one in full time physical mode and another in Open and Distance Learning (ODL)/Online mode are allowed simultaneously.

  3. ((c))

    Degree or diploma programmes under ODL/Online mode shall be pursued with only such Higher Education Institutions (HEIs) as recognized by UGC/Statutory Council/Govt. of India for running such programmes.

  4. ((d))

    A student can pursue one full time academic programmes along with Ph.D. in physical mode.

Show Answer
Answer: ((d))

A student can pursue one full time academic programmes along with Ph.D. in physical mode.

The correct answer is - A student can pursue one full-time academic programme along with Ph.D. in physical mode.

Key Points

  • UGC Guidelines (2022)
  • The University Grants Commission (UGC) issued guidelines in 2022 to facilitate students in pursuing two academic programmes simultaneously.
  • The guidelines explicitly do not permit pursuing a full-time programme along with a Ph.D. in physical mode.
  • Reason for Restriction
  • Pursuing a Ph.D. requires significant research work and time commitment, making it difficult to effectively manage another full-time academic programme in physical mode.
  • UGC aims to ensure that students dedicate sufficient time and resources to their Ph.D. research without additional burdens.

Additional Information

  • Other Permitted Combinations
  • Students can pursue two full-time programmes in physical mode, provided the class timings do not overlap.
  • It is also allowed to pursue one full-time physical mode programme and another programme in Open and Distance Learning (ODL) or online mode simultaneously.
  • Recognized Institutions
  • Programmes under ODL or online mode must be offered by UGC-recognized Higher Education Institutions (HEIs) or those approved by the Government of India.
  • This ensures that the quality and standards of the academic programmes are maintained.

In the light of the above statements, choose the most appropriate answer from the options given below:

  1. ((a))

    Both (A) and (R) are correct and (R) is the correct explanation of (A)

  2. ((b))

    Both (A) and (R) are correct but (R) is not the correct explanation of (A)

  3. ((c))

    (A) is correct but (R) is not correct

  4. ((d))

    (A) is not correct but (R) is correct

Show Answer
Answer: ((b))

Both (A) and (R) are correct but (R) is not the correct explanation of (A)

The correct answer is - Both (A) and (R) are correct but (R) is not the correct explanation of (A)

Key Points

  • Assertion (A): Certain degree of intelligence is required for creative thinking
  • Creative thinking involves problem-solving, innovation, and original ideas, which demand a base level of intelligence.
  • Research shows that individuals require a certain threshold of cognitive ability to process information and generate creative solutions.
  • Reason (R): Students with high intelligence are not necessarily creative
  • Intelligence and creativity are related but distinct constructs. High intelligence does not guarantee creativity since creativity also depends on divergent thinking and imagination.
  • Creativity involves a combination of personality traits, such as openness to experience, and environmental factors, which are not solely determined by intelligence.
  • Although both statements are correct, the reason (R) does not provide a direct explanation for the assertion (A).

Additional Information

  • Threshold Theory of Creativity
  • This theory suggests that up to a certain level, intelligence and creativity are positively correlated.
  • Beyond this level, higher intelligence does not necessarily lead to increased creativity.
  • Factors influencing creativity
  • Environmental factors: A supportive and stimulating environment fosters creative thinking.
  • Personality traits: Openness, perseverance, and risk-taking are critical for creativity.
  • High intelligence vs. creativity
  • High intelligence is associated with logical reasoning and analytical skills, while creativity involves thinking outside the box.
  • Individuals with average intelligence but high creativity can often outperform highly intelligent individuals in creative tasks.

  • Cache: High-speed memory used to store frequently accessed data for faster CPU access.
  • Difference Between Primary and Secondary Memory:
  • Primary Memory: Faster, volatile (except ROM), and directly accessible by the CPU.
  • Secondary Memory: Slower, non-volatile, and used for long-term data storage.
  • Examples of secondary memory include HDDs, SSDs, and USB drives.

Read the following passage and answer the questions:

John B. Watson, an animal experimentalist who argued that all human action is merely a conditioned response to external environmental stimuli, first popularized stimulus-response psychology. Watson's theory became known as behaviorism in recognition of its narrow focus on isolated human behaviors. Behaviorists rejected psychology's widely held assumption that higher mental processes (that is, conscious thought or reflection) ordinarily control human action. In contrast to such "mentalist" views, behaviorists argued that the only purpose served by consciousness was to rationalize behaviors after they are triggered by external stimuli. Behaviorists attempted to purge all mentalist terms from their theories and to deal strictly with observable variables environmental stimuli on the one hand and behaviors on the other. By studying the associations that existed between specific stimuli and specific behaviors, behaviorists hoped to discover previously unknown causes for action. One of the central notions in behaviorism was the idea of conditioning. Behaviorists argued that most human behavior is the result of conditioning by the external environment. We are conditioned to act in certain ways by positive and negative stimuli - we act to gain rewards or avoid punishments.

46

In the passage, instead of the word 'purge', which of the following words can be used:

  1. ((a))

    atone

  2. ((b))

    acquit

  3. ((c))

    kill

  4. ((d))

    cleanse

Show Answer
Answer: ((d))

cleanse

The correct answer is Option 4: cleanse.

 

Key Points

  • In the passage, behaviorists attempted to "purge" mentalist terms from their theories.
  • The word "purge" means to remove or eliminate something completely.
  • "Cleanse" means to purify or rid something of unwanted elements.
  • Thus, "cleanse" is the closest synonym in the given context.

Therefore, the correct answer is Option 4.

 

Additional Information

  • Option 1: atone – Means to make amends for wrongdoing, not to remove.
  • Option 2: acquit – Means to declare someone not guilty, unrelated to removal.
  • Option 3: kill – Means to put to death, not appropriate in this context.
47

One widely - held assumption of Psychology is that:

  1. ((a))

    Conscious thought usually controls human action.

  2. ((b))

    The purpose of consciousness is only to rationalize behaviour.

  3. ((c))

    Human action is always a conditioned response.

  4. ((d))

    Conditioning by the external environmental factors leads to a specific behaviour.

Show Answer
Answer: ((a))

Conscious thought usually controls human action.

The correct answer is Option 1: Conscious thought usually controls human action.

 

Key Points

  • The passage states that behaviorists rejected psychology’s widely held assumption.
  • That assumption was that higher mental processes (conscious thought or reflection) control human action.
  • Thus, mainstream psychology believed that conscious thought ordinarily governs behaviour.
  • Behaviorism opposed this view by emphasizing external stimuli and conditioning.

Therefore, the correct answer is Option 1.

 

Additional Information

  • Option 2: This reflects the behaviorist view, not the widely held assumption of psychology.
  • Option 3: This is Watson’s behaviorist claim, not the traditional psychological assumption.
  • Option 4: This describes conditioning theory, central to behaviorism, not mainstream psychology’s earlier belief.
48

Behaviorists do not recognise which of the following in their study of human action ?

  1. ((a))

    Conscious thought

  2. ((b))

    Environmental stimuli

  3. ((c))

    Negative stimulus

  4. ((d))

    Isolated human behavior

Show Answer
Answer: ((a))

Conscious thought

The correct answer is Option 1: Conscious thought.

 

Key Points

  • Behaviorists rejected the idea that higher mental processes control human action.
  • They attempted to remove all mentalist terms from their theories.
  • They focused only on observable variables such as environmental stimuli and behavior.
  • Therefore, they did not recognize conscious thought as a valid factor in explaining human action.

Therefore, the correct answer is Option 1.

 

Additional Information

  • Option 2: Environmental stimuli are central to behaviorist theory.
  • Option 3: Negative stimulus is part of conditioning (avoid punishment).
  • Option 4: Behaviorism focuses on isolated human behaviors.
49

According to Behaviorism, all human action is :

  1. ((a))

    Conscious behaviour

  2. ((b))

    Isolated action

  3. ((c))

    Conditioned response

  4. ((d))

    Conscious thought

Show Answer
Answer: ((c))

Conditioned response

The correct answer is Option 3: Conditioned response.

 

Key Points

  • The passage states that Watson argued all human action is a conditioned response to external stimuli.
  • Behaviorism emphasizes the role of environmental stimuli in shaping behavior.
  • It rejects the idea that conscious thought controls human action.
  • Thus, according to behaviorism, human behavior results from conditioning.

Therefore, the correct answer is Option 3.

 

Additional Information

  • Option 1: Behaviorism does not consider behavior to be primarily conscious.
  • Option 2: Isolated action refers to focus on behavior, but not the definition of all human action.
  • Option 4: Conscious thought is rejected as the controlling factor in behaviorism.

When people want a reward, they behave in a certain way because of :

  1. ((a))

    motivation

  2. ((b))

    positive stimulus

  3. ((c))

    reflection

  4. ((d))

    negative stimulus

Show Answer
Answer: ((b))

positive stimulus

The correct answer is Option 2: positive stimulus.

 

Key Points

  • The passage explains that behaviorists believed human actions are responses to external environmental stimuli.
  • It clearly states that people act to gain rewards or avoid punishments.
  • A reward functions as a positive stimulus that conditions individuals to behave in a certain way.
  • Therefore, when people want a reward, their behavior is driven by a positive stimulus.

Therefore, the correct answer is Option 2.

 

Additional Information

  • Option 1: Motivation – The passage focuses on external conditioning rather than internal drives like motivation.
  • Option 3: Reflection – Behaviorists rejected the idea that conscious reflection controls behavior.
  • Option 4: Negative stimulus – Negative stimuli are associated with avoiding punishment, not gaining rewards.
