UGC NET Paper 1: Held on 6th Mar 2023 Shift 1 (Previous Year Paper)

Key Points

When media create images or mental pictures in the minds of their audience, they act as agents of consonance.

• Consonance refers to the degree of agreement or consistency between a message and the existing beliefs, attitudes, or values of the audience.
• When media messages are consistent with the audience's preexisting beliefs, attitudes, or values, they create a sense of harmony and reinforce these beliefs.
• This can result in the audience becoming more convinced of the message and less likely to challenge or question it.

Western concepts of communication are often based on individualism, which emphasizes the importance of personal autonomy, self-expression, and individual achievement.

 Key Points

• In Western culture, communication is viewed as a tool for expressing oneself, making individual choices, and asserting personal interests. Western communication also places a high value on directness, clarity, and assertiveness in communication.
• As a result, communication in Western societies tends to be more explicit and goal-oriented, and individualistic values are emphasized over collective or communal values.
• This approach to communication can be contrasted with other cultures, such as those that emphasize collectivism, where communication is viewed more as a means of maintaining social harmony and preserving group relationships.

Key Points

Charles Pierce, a renowned American philosopher and logician, developed a theory of semiotics, the study of signs and symbols, which is widely used in various fields like linguistics, anthropology, psychology, and communication studies.

Important Points

Pierce classified signs into three categories, based on the nature of their relationship with their referent, which are:

1. Iconic Signs:

• Iconic signs are those signs that resemble their referent, either physically or by convention.
• For example, a portrait of a person or a diagram of a machine is an iconic sign.
• These signs rely on resemblance, and the viewer recognizes the referent by relating the sign to a visual or mental image of the referent.
• In other words, the sign is a likeness of its referent.

2. Indexical Signs:

• Indexical signs are those signs that indicate a relationship or association with their referent, rather than resembling them.
• These signs have a direct and causal relationship with their referent.
• For example, smoke is an indexical sign of fire, and a pointing finger is an indexical sign of the object being pointed at.
• The viewer recognizes the referent by relating the sign to the context of the situation.

3. Symbolic Signs:

• Symbolic signs are those signs that have an arbitrary or conventional relationship with their referent.
• These signs have no inherent resemblance or relationship with their referent.
• For example, words, numbers, and traffic signals are symbolic signs.
• The viewer recognizes the referent by understanding the social and cultural conventions that assign meaning to the sign.

In conclusion, Pierce's classification of signs into iconic, indexical, and symbolic categories is significant because it allows us to understand how signs work in communication and how meanings are conveyed through signs.

Important Points 

Hence, the correct match is A - III, B - IV, C - I, D - II.

Important Points 

Statement I: According to some experts, communication reflects the primary group affiliation of a person.

• This statement suggests that a person's communication style and patterns reflect the primary groups to which they belong, such as family, friends, and cultural or social communities.
• People learn communication styles and norms within their primary groups, and these patterns become a part of their identity.
• For example, a person who grew up in a culture that values indirect communication may have a hard time being direct in their communication style.
• On the other hand, a person who has spent most of their life in a more individualistic society may prefer direct communication.
• Communication, therefore, is seen as an extension of group identity and values.

Hence, Statement I is correct. 

Statement II: Communication should be understood within the broad social structure and process.

• This statement suggests that communication is not just an individual act but is shaped by broader social structures and processes.
• Communication occurs within specific contexts such as cultural, economic, and political environments.
• For example, in a hierarchical organization, communication may be more formal and follow a clear chain of command.
• Similarly, in different cultures, communication styles may differ significantly due to differing social structures and norms.
• Understanding these broader social structures and processes is important for understanding communication patterns and how they affect individuals and societies.

Hence, Statement II is correct. 

Therefore, Both Statement I and Statement II are True.

Shortcut Trick

Let the Principal amount be 100%.

First Simple Interest (SI₁) = 5% × 5 years = 25% of Principal

Second Simple Interest (SI₂) = 4% × 4 years = 16% of Principal

Difference in interest = 25% − 16% = 9% of Principal

Given that this difference is Rs. 900:

⇒ 9% of Principal = Rs. 900

⇒ 100% of Principal = (900 ÷ 9) × 100 = Rs. 10,000

∴ The correct answer is Rs. 10,000.

Alternate Method

Given:

• Rate of interest for first case (R₁) = 5% per annum

• Time period for first case (T₁) = 5 years

• Rate of interest for second case (R₂) = 4% per annum

• Time period for second case (T₂) = 4 years

• Difference between the two simple interests = Rs. 900

Formula Used:

Simple Interest (SI) = (P × R × T) ÷ 100

Where P = Principal amount, R = Rate of interest per annum, and T = Time period in years.

Calculations:

Let the Principal amount be P.

For the first case:

⇒ SI₁ = (P × 5 × 5) ÷ 100

⇒ SI₁ = 25P ÷ 100

For the second case:

⇒ SI₂ = (P × 4 × 4) ÷ 100

⇒ SI₂ = 16P ÷ 100

According to the question, the difference between the two interests is Rs. 900:

⇒ SI₁ − SI₂ = 900

⇒ (25P ÷ 100) − (16P ÷ 100) = 900

⇒ (25P − 16P) ÷ 100 = 900

⇒ 9P ÷ 100 = 900

⇒ 9P = 900 × 100

⇒ 9P = 90000

⇒ P = 90000 ÷ 9

⇒ P = 10000

Thus, the principal amount is Rs. 10,000.

Explanation of other options:

• Option (1) Rs. 9,000: If P = Rs. 9,000, then SI₁ = (9000 × 25) ÷ 100 = Rs. 2,250 and SI₂ = (9000 × 16) ÷ 100 = Rs. 1,440. The difference is Rs. 810, which is incorrect.

• Option (2) Rs. 10,500: If P = Rs. 10,500, then SI₁ = (10500 × 25) ÷ 100 = Rs. 2,625 and SI₂ = (10500 × 16) ÷ 100 = Rs. 1,680. The difference is Rs. 945, which is incorrect.

• Option (4) Rs. 12,000: If P = Rs. 12,000, then SI₁ = (12000 × 25) ÷ 100 = Rs. 3,000 and SI₂ = (12000 × 16) ÷ 100 = Rs. 1,920. The difference is Rs. 1,080, which is incorrect.

∴ The correct answer is Rs. 10,000.

Additional Information

Simple Interest (SI)

SI = (P × R × T) ÷ 100, where P is Principal, R is Rate of Interest per annum, and T is Time in years.

Total Amount (A)

A = Principal (P) + Simple Interest (SI) = P × (1 + (R × T) ÷ 100).

Difference between SI and CI for 2 Years

Difference (D) = P × (R ÷ 100)².

Logic: The positional value of alphabets of the first term is shifted two places ahead in the English alphabet.

According to the logic, the code for 'PROFESSOR';

Similarly, 

So, the code for 'SCIENTIST' is 'UEKGPVKUV'.

According to the information, Family tree is as follow;

So, the man 'Q' is father of the person in the picture 'P'.

According to the given directions,

• A girl starts walking in the south direction from a point U. She walks 50 meters and then turns to her right and walks 30 meters.

• She again turns right and walks for 40 meters.

​

• Finally, she moves east wards and goes 40 meters stopping at point W.

So, the distance between U and W is,

⇒ (UA)² + (WA)² = (WU)²

⇒ (10)² + (10)² = (WU)²

⇒ 100 + 100 = 200

⇒ WU = 10√2 m

Hence, the correct answer is "10√2 m".

The logic followed here is,

So, the next term is "1851".

The argument presented in the statement is an example of the fallacy of division.

Key PointsThe argument presented in the statement is an example of the fallacy of division.

This fallacy occurs when a characteristic of a group or entity as a whole is incorrectly assumed to apply to each individual component or member of that group.

In this case, the argument assumes that the good growth in profits of the soft drinks sector as a whole means that each individual soft drinks company is making good profits. However, this assumption may not be true because the profitability of each company may vary depending on factors such as market share, brand recognition, and pricing strategies.

Therefore, the argument presented in the statement is a fallacy of division because it wrongly infers that a characteristic of the whole group (sector) applies to each individual part (company), without considering other factors that may affect individual performance.

Additional InformationSlippery slope is a fallacy that suggests that taking a small initial step will inevitably lead to a chain of events resulting in an extreme outcome, without providing sufficient evidence for such a claim.

Hasty generalization is a fallacy that occurs when a conclusion is made based on insufficient or unrepresentative evidence.

The statements A, C, and D are logically equivalent.

 Key PointsIn categorical syllogisms, the terms A and B refer to categories or classes of things, and the statements describe the relationships between those classes.

A. No aeroplanes are electric vehicles. (No A is B.)

C. No electric vehicles are aeroplanes. (No B is A.)

D. All aeroplanes are non-electric vehicles. (All A are non-B.)

To show that these statements are equivalent, we can use the rules of conversion, obversion, and contraposition in categorical syllogisms.

Conversion of A: No A is B can be converted to No B is A. Obversion of A: No A is B can be obverted to All A are non-B. Contraposition of C: No B is A can be contraposed to All non-A are non-B.

Thus, statement A can be converted to statement C, and statement A can be obverted to statement D. Statement C can be contraposed to statement D.

Therefore, statements A, C, and D are logically equivalent.

Key PointsThe correct answer is "4) A and B Only".

Statement A: "All aeroplanes are polluting vehicles" is the negation of Statement B: "No aeroplanes are polluting vehicles."

The other pairs do not negate each other entirely. For example, "Some aeroplanes are polluting vehicles" doesn't contradict "All aeroplanes are polluting vehicles," because both can be true at the same time.

Similarly, "Some aeroplanes are not polluting vehicles" doesn't contradict "No aeroplanes are polluting vehicles" because both can be true at the same time.

Additional Information

• The statements A and B are so related that one is the denial or the negation of the other, and similarly, the statements C and D are so related.
• Statement A "All aeroplanes are polluting vehicles" is a universal affirmative statement, meaning it applies to all members of a category.
• In contrast, statement B "No aeroplanes are polluting vehicles" is the negation of statement A, as it denies the existence of any overlap between the categories of aeroplanes and polluting vehicles.
• Similarly, statement C "Some aeroplanes are polluting vehicles" is an existential statement, meaning it asserts the existence of at least one member of the category of aeroplanes that belongs to the category of polluting vehicles.

Key Points

If the statement 'No aeroplanes are electric vehicles' is given as true, then the statement 'Some aeroplanes are not electric vehicles' can be immediately inferred to be true.

This is because the original statement implies that there is no overlap between the categories of aeroplanes and electric vehicles, which means that there must be some aeroplanes that do not belong to the category of electric vehicles.

Therefore, the statement 'Some aeroplanes are not electric vehicles' is necessarily true.

Key Points

According to the Classical Indian School of Logic (Nyaya), the fallacy of Sadharana occurs when the middle term in a syllogism is too wide or general, such that it encompasses too many things to be a useful basis for drawing a conclusion.

• In the given argument, "the hill has fire because it is knowable," the middle term "knowable" is too wide or general to establish a valid conclusion.
• While it may be true that fire is knowable, it does not follow that the hill necessarily has fire.
• This argument fails to establish a clear and specific relationship between the hill and the presence of fire.

Therefore, the given argument involves the fallacy of Sadharana.

Formative evaluation is an ongoing process of gathering feedback and information during the learning process in order to improve the learning experience.

Key Points

• Formative evaluation is focused on providing feedback that can be used to modify or adjust the learning experience while it is still ongoing.
• One of the ways that teachers can conduct formative evaluation is by providing immediate feedback to students during class through answering questions and clarifying doubts.
• This helps students to stay on track and understand the material being taught.
• However, formative evaluation can also involve a variety of other methods such as quizzes, observations, feedback, self-assessments, peer-assessments, and more.
• The goal is to provide ongoing feedback to the learner so that they can monitor their progress and make adjustments to their learning strategies or behavior as needed.

Overall, the statement "The teacher clarifies the doubts of the students in the class itself" is related to formative evaluation which is providing immediate feedback to students during class.

Key Points 

Hence the correct match is A - II, B - IV, C - I, D - III

Additional Information

• Reflection: The teacher asks students to reflect on their own learning, considering what strategies were effective and what areas they still need to work on.
• Exploration: The teacher provides opportunities for students to explore a topic or concept on their own, encouraging curiosity and creativity.

Key Points

• The approach of accepting knowledge because people have agreed upon, following a reasonable argument is known as A- priori.
• This means that knowledge is accepted based on logical deduction or prior reasoning, rather than empirical evidence or experience. In other words, a priori knowledge is considered to be true or valid without the need for further observation or testing.
• This approach is often contrasted with a posteriori, which involves knowledge gained through experience or empirical evidence.

Additional InformationIn research, there are two main approaches to accepting knowledge:

• Deductive reasoning: This is an a priori approach, where knowledge is accepted based on logical deduction or reasoning.
• It involves starting with a general theory or hypothesis and then testing it with specific observations or data to see if it is supported.
• Inductive reasoning: This is an a posteriori approach, where knowledge is accepted based on empirical evidence or observation.
• It involves collecting specific observations or data and then using them to develop a general theory or hypothesis.

Both deductive and inductive reasoning have their strengths and weaknesses, and they are often used in combination in research. Deductive reasoning is useful for testing existing theories and hypotheses, while inductive reasoning is useful for generating new theories and hypotheses.

A measurement scale is a system for assigning values or numbers to a particular attribute or characteristic being measured.

Key Points

• Nominal scale is a measurement scale used for data that can be placed into distinct categories or groups, where the values assigned are arbitrary and there is no inherent order or numerical relationship between the categories.
• It is the lowest level of measurement in which data is classified into mutually exclusive categories.
• Values assigned to nominal scale of measurement are arbitrary which means that they do not have any numerical value or meaning beyond simply identifying a category or group.
• In other words, nominal scales are used to categorize data into distinct groups or labels, but there is no inherent order or numerical relationship between the categories.
• The categories are usually represented by numbers or symbols, but these values are purely arbitrary and could be replaced by any other set of values without changing the meaning or structure of the data.
• For example, assigning the values of 1, 2, 3 to different colors like Red, Green, Blue in a survey questionnaire is arbitrary and the same data could be represented by assigning different values like 3, 7, 9 to the same colors.

Ethics in scientific research refers to the set of moral principles and values that guide the conduct of research involving human or animal subjects, as well as the dissemination of research findings. This includes ensuring informed consent, protecting privacy and confidentiality, minimizing harm and risks, and ensuring scientific integrity.

 Key Points

• Junk science refers to use of scientific research to promote one's own cause inappropriately.
• Research that is flawed, unreliable, or based on incomplete or biased data, and is often used to support false or unscientific claims.
• Junk science can have serious consequences, particularly when it is used to make decisions or shape public policy.
• It can also undermine public trust in scientific research and lead to a general disregard for scientific evidence.
• Junk science can also refer to the inappropriate use of scientific research to promote a particular agenda or belief, even if the research itself is sound.

Additional Information

• Improper science refers to research that is conducted using unethical or fraudulent methods.
• Routine science refers to research that is conducted using standard and established methods.
• Unscience refers to research that is conducted without adherence to scientific principles or using methods that lack scientific validity.

Key Points

 Cloud Computing:

• Cloud computing refers to the delivery of computing services over the internet, which can include servers, storage, databases, networking, software, analytics, and more.
• Rather than having to manage physical hardware and infrastructure on-site, cloud computing allows users to access computing resources on demand, from anywhere with an internet connection.
• Cloud computing can offer a range of benefits, such as cost savings, scalability, flexibility, and the ability to access data and applications from anywhere.
• Instead of owning and maintaining their own computing infrastructure, businesses and individuals can access these resources from cloud service providers, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud.

Hence, Computing resources that can be accessed on demand, like electricity from a utility is cloud computing.

Important Points

A. Network users can communicate by email and instant messenger:

• This statement is true.
• One of the main advantages of a computer network is the ability to communicate with other users on the network.
• Email and instant messaging are two common ways to communicate on a network.
• Email allows users to send messages to one another, while instant messaging allows for real-time chat.

B. Files can easily be shared between users:

• This statement is true.
• Another major advantage of a computer network is the ability to share files between users.
• This can be useful for collaboration on projects or for accessing files from multiple computers.

C. Viruses cannot be spread to other computers throughout a computer network:

• This statement is false.
• In fact, viruses can easily spread through a computer network if proper precautions are not taken.
• It is important to have up-to-date antivirus software installed on all computers on the network and to educate users on safe browsing and email practices to minimize the risk of virus infections.

D. It is possible for many users to access and share one printer on a network:

• This statement is true.
• A printer can be connected to a network, allowing many users to access it and print documents from their own computers.
• This can be a cost-effective solution for small businesses or households with multiple users.

Hence, A, B and D Only are correct.

Important Points

Statement I: International Solar Alliance (ISA) was launched on the side-lines of COP24.

• The International Solar Alliance (ISA) was actually launched on November 30, 2015, in Paris, France, on the side-lines of the United Nations Climate Change Conference, also known as COP21.
• The ISA is an alliance of more than 120 countries, most of which are located between the Tropics of Cancer and Capricorn, with the aim of promoting the use of solar energy and reducing dependence on fossil fuels.

Hence, this statement is incorrect.

Statement II: ISA was launched by Prime Minister Narendra Modi and President of France, Emmanuel Macron.

• The International Solar Alliance was jointly launched by the Prime Minister of India, Narendra Modi, and the President of France, François Hollande, on November 30, 2015.
• Emmanuel Macron became the President of France in May 2017, succeeding François Hollande.
• So, the statement is incorrect in terms of the person who launched ISA from France's side.

Hence, this statement is incorrect.

Therefore, both Statement I and Statement II are False.

Key Points 

The correct match is given below:

Important Points

A. Hazard Identification:

• This step involves identifying which hazards are present and evaluating their potential to cause harm.
• This is typically done by reviewing available data on the toxicity of the substance and any known exposure pathways.
• The goal is to determine which populations are at risk and which health effects may occur.

B. Dose response assessment:

• This step involves characterizing the relationship between the dose received and the likelihood of an adverse health effect.
• This can be done by analysing data from animal studies or human epidemiological studies.
• The goal is to determine the threshold below which no adverse effects are expected to occur and the severity of the effects at higher doses.

C. Exposure assessment:

• This step involves quantifying the exposure of the population to the hazard.
• This can be done by measuring the concentration of the substance in the environment or by estimating exposure through various pathways (e.g., inhalation, ingestion, dermal contact).
• The goal is to determine the extent of exposure and any factors that may influence it.

D. Risk characterization:

• This step involves combining the information from the previous steps to estimate the overall risk posed by the hazard.
• This can be done by comparing the estimated exposure to the dose-response relationship and determining the likelihood and severity of adverse effects.
• The goal is to provide a summary of the risks and uncertainties associated with the hazard, and to identify any data gaps or areas of uncertainty that may require further investigation.

Hence, the correct match is A - IV, B - III, C - I, D - II.

Important Points

Statement I: Central University is established under an act of Parliament.

• Central universities in India are established under the Central Universities Act, 2009, which is an act of Parliament.
• This act provides for the establishment of universities for teaching and research in various states and territories of India.
• Central universities are fully funded by the Government of India and are governed by the University Grants Commission.

​Hence, this statement is correct. 

Statement II: The Prime Minister of India acts as the visitor of the Central University.

• The President of India, not the Prime Minister, acts as the visitor of the Central University.
• The President is the ceremonial head of the university and has the power to review its functioning and make necessary recommendations.
• The President appoints the Vice-Chancellor of the Central University, who is the chief executive officer of the university and responsible for its day-to-day administration.

Hence, this statement is incorrect.

Important Points

In the ancient period in southern parts of India, the centres of learning and teaching were mainly Agraharas, Ghatikas, and Brahmapuris.

Agraharas:

• Agraharas were village settlements or residential complexes given to learned Brahmins by kings or wealthy individuals.
• The Brahmins living in agraharas were supposed to teach and perform religious duties for the community.
• These agraharas were centers of learning and attracted students from all over India.

Ghatikas:

• Ghatikas were schools or institutions of higher learning that were established in association with temples or royal courts.
• These institutions offered a wide range of subjects such as astronomy, mathematics, logic, and grammar, in addition to religious texts.

Brahmapuris:

• Brahmapuris were the settlements of the Brahmins who were engaged in teaching and performing religious duties.
• These settlements were usually located near temples, and the Brahmins living in Brahmapuris were supposed to conduct the daily rituals of the temple.

Therefore, the correct answer is A, B and C only, as Agraharas, Ghatikas, and Brahmapuris served as centers of learning and teaching during the ancient period in southern parts of India.

Additional Information

Maktabas, on the other hand, were centers of Islamic learning that were established during the medieval period in India. They were similar to madrasas and were usually associated with mosques.

Calculation:

The total number of employees in the HR department = 12%

of 1800 = 216

The number of recently promoted employees in the HR

department is 11% of 600 = 66

So, the percentage of employees who got promoted from the

HR department is (66/216) × 100 = 30.56%

Therefore, the answer is 30.56%.

Calculation:

The total number of employees who got promoted from all

the departments together = 600

The total number of employees working in all the

departments together = 1800

Therefore, the percentage of employees who got promoted

All the departments together is (600/1800) × 100 =

33.33% = 33%(approx)

Calculation:

The total number of employees in the Production department

= 35% of 1800 = 630 

The total number of male employees in the Production

department is 50% of 1020 = 510

So, the number of female employees in the Production

department is 630 - 510 = 120.

The total number of employees in the Marketing department

= 18% of 1800 = 324.

The total number of male employees in the Marketing

department =15% of 1020 =153.

So, the number of female employees in the Marketing

department is 324 - 153 = 171.

Therefore, the total number of female employees working

in the Production and Marketing departments together is

120 + 171 = 291.

The number of recently promoted employees in the IT

department = 26% of 600 = 156.

If half of the employees who got promoted from the IT

department were males = 156/2 = 78

The percentage of males who got promoted from the IT

department then would be (78 / 156) × 100 = 50%

The total number of male employees in the IT department =

20% of 1020 = 204.

So, the percentage of males who got promoted from the IT

department is (78 / 204) × 100 = 38.24%. = 38% (approx)

Calculation:

The total number of employees in the Accounts department =

20% of 1800 = 360

The total number of male employees in the Accounts

department = 5% of 1020 = 51

So, the number of female employees in the Accounts

department is 360 - 51 = 309.

The correct response is that Akshay's teacher can help alleviate his anxiety in the classroom by providing structure, organizational tools, and choices.

 Key PointsThis can be done in several ways, including:

• Providing a structured routine: Establishing a predictable routine in the classroom can help reduce anxiety for students like Akshay who may be struggling with changes in their home life.
• This can include having a set schedule for activities and transitions throughout the day.
• Offering organizational tools: Providing Akshay with tools like a planner or checklist can help him feel more organized and in control of his environment.
• This can also help him stay on track with assignments and deadlines.
• Giving choices: Providing Akshay with choices in the classroom can help him feel more empowered and in control of his learning.
• This can include offering choices in how he completes an assignment or engages with a lesson.

Overall, by providing structure, organizational tools, and choices, Akshay's teacher can help create a supportive and nurturing classroom environment that can help alleviate his anxiety and support his emotional well-being.

The correct answer is A, B, C, and D.

 Key PointsParticipants in research can be categorized based on their attitudes, behaviors, and characteristics that may affect the study outcomes.

• Good participants are those who are compliant, willing to participate and adhere to the study protocols.
• Negative participants may be uncooperative, unreliable, or disruptive during the study.
• Faithful participants are committed and show a high level of engagement with the study.
• Apprehensive participants may be anxious or concerned about the study procedures or outcomes and may require additional support or reassurance from the researchers.

Confusion PointsIn research, participant categories can help researchers to identify differences or similarities between groups and to analyze data more effectively.

However, it is important to use these categories thoughtfully and to avoid stereotyping or discriminating against study participants based on these characteristics.

Thus, traditional participants may have a strong cultural or social identity that influences their attitudes and behaviors during the study.

Hence traditional participants cannot be considered a participant category.

Important Points 

Statement A: This connection does not allow you to use the land phone at the same time as being connected to the Internet.

• This statement is false.
• Broadband connections typically use a separate line or frequency range than land phone lines, allowing for simultaneous use of both services.
• This connection does not allow you to use the land phone at the same time as being connected to the Internet.

Statement B: This connection allows a wireless connection.

• This statement is true.
• Broadband connections can be set up with a wireless router, allowing multiple devices to connect to the internet without the need for physical cables.
• This is useful for homes or offices where multiple devices need to be connected to the Internet simultaneously, such as smartphones, tablets, laptops, and smart home devices.

Statement C: You are always connected to the Internet.

• This statement is true.
• Unlike dial-up connections, broadband connections are always on, providing constant access to the internet without the need to dial in each time.
• This allows for faster and more convenient access to online services and content.
• However, some broadband connections may experience occasional downtime or interruptions due to technical issues or maintenance.

Hence, the correct answer is B and C Only

Important Points 

Statement I: Turbulent and rapidly flowing waters are generally depleted in oxygen.

• Turbulent and rapidly flowing waters can actually be highly oxygenated.
• This is because the turbulent flow allows for greater mixing with the air and helps to increase the amount of oxygen in the water.
• In addition, the movement of water over rocks and other structures can help to aerate the water and increase oxygen levels.

Hence, this statement is incorrect.

Statement II: Adding organic materials, such as sewage or paper pulp, to water stimulates activity and oxygen consumption by decomposers.

• When organic materials are added to water, they provide a food source for decomposers such as bacteria and fungi.
• These organisms consume the organic materials, and, in the process, they use up oxygen.
• As the oxygen is depleted, other organisms in the water that require oxygen can become stressed or die.
• This is why adding organic materials to water can lead to a decrease in oxygen levels and can have negative impacts on aquatic ecosystems.

Hence, this statement is correct.

Hence, Statement I is Incorrect but Statement II is Correct.

Key Points

 Tsunamis:

• Tsunamis are often called "harbour waves" because they are most commonly observed in shallow waters near shorelines and in harbours.
• The term "harbour wave" is actually a misnomer, as tsunamis are not necessarily created in harbours, nor are they actual waves caused by winds.
• Instead, they are typically caused by large undersea earthquakes, landslides, or volcanic eruptions that displace large amounts of water, creating a series of waves that propagate outward from the source.
• As these waves approach shallow water near shorelines, they become compressed and increase in height, which can cause devastating damage to coastal communities.
• The term "tsunami" comes from the Japanese words "tsu" (meaning harbour) and "nami" (meaning wave), which reflects the common observation of these destructive waves in Japanese harbours.

Hence, meaning of Tsunami is Harbour Wave.

Cognitive Apprenticeship is a learning model that emphasizes learning through active engagement in a community of practice, where learners gradually acquire the knowledge and skills of the community's practices.

 Key PointsThe Cognitive Apprenticeship model is made up of several key components or stages, which are modelling, coaching, scaffolding, articulation, reflection, and exploration.

These stages are meant to support learners as they gradually acquire the knowledge and skills of the community of practice.

Here is a brief explanation of each stage in the sequence of using the Cognitive Apprenticeship model in the classroom:

Modelling: In this stage, the teacher or expert demonstrates a particular skill or concept for the learner.

• This could be through lectures, videos, or live demonstrations. The purpose of this stage is to provide a clear and concrete example of what the learner should be able to do or understand.

Coaching: After the modelling stage, the teacher provides individualized support and guidance to the learner.

• This could be through one-on-one coaching sessions, feedback on assignments or tasks, or personalized instruction.
• The purpose of this stage is to help the learner develop their skills and understanding.

Scaffolding: In this stage, the teacher provides structured support for the learner to help them gradually build their skills and understanding.

• This could be through breaking down tasks into smaller, more manageable steps, or providing prompts or cues to guide the learner's thinking.
• The purpose of this stage is to help the learner develop their skills and understanding in a structured and supported way.

Articulation: In this stage, the learner is encouraged to explain their thinking and reasoning.

• This could be through group discussions, presentations, or written reflections.
• The purpose of this stage is to help the learner develop their ability to articulate their thinking and reasoning, which is a key skill in the community of practice.

Reflection: In this stage, the learner is encouraged to reflect on their learning experiences.

• This could be through self-assessment, peer assessment, or feedback from the teacher.
• The purpose of this stage is to help the learner develop their ability to reflect on their learning and identify areas for improvement.

Exploration: In this stage, the learner is encouraged to apply their learning in new and unfamiliar contexts.

• This could be through project-based learning, case studies, or simulations.
• The purpose of this stage is to help the learner develop their ability to apply their learning in real-world situations and to develop their expertise in the community of practice.

Thus, the sequence of using the Cognitive Apprenticeship model in the classroom is designed to provide learners with structured and supported learning experiences that gradually build their skills and understanding within a community of practice.

Evaluation refers to the process of systematically collecting and analyzing data to assess the effectiveness, efficiency, and impact of a program, intervention, or policy.

Key PointsThe main types of evaluation include:

• Formative evaluation, which is conducted during program implementation to improve and modify the program.
• Summative evaluation, which is conducted after program completion to determine the overall impact and effectiveness of the program.

The process evaluation, which assesses the implementation and delivery of the program to ensure it is being carried out as intended.

Other types of evaluation include impact evaluation, cost-benefit analysis, and needs assessment.

 Important Points

• Summative evaluation is an assessment process used to determine the effectiveness and impact of a program or intervention after it has been completed.
• It typically involves collecting data and analyzing the outcomes to make conclusions about the success of the program in achieving its goals.
• Summative evaluation is often used to inform decisions about the continuation, modification, or termination of the program.

Therefore, summative evaluation is also known as impact evaluation, as it assesses the overall impact or effect of the program on the intended outcomes.

Important Points 

Statement I: In an email system, Bcc: allows recipients to be visible to all other recipients of the message.

• Bcc stands for Blind Carbon Copy, which is a feature in email systems that allows the sender to send a copy of an email to a recipient without including their email address in the "To" or "Cc" fields.
• This means that the other recipients of the email will not see that person's email address.
• Bcc is commonly used when the sender wants to keep the identity of some recipients confidential, or when they want to avoid cluttering the email with too many addresses.

Hence, this statement is false. 

Statement II: VoIP is the use of the Internet to make phone calls.

• VoIP stands for Voice over Internet Protocol, which is a technology that allows voice communication over the Internet.
• It uses the Internet Protocol (IP) to transmit voice data in the form of digital packets.
• VoIP is a popular alternative to traditional phone service because it is often cheaper and provides additional features like video conferencing, call recording, and call forwarding.
• Some popular VoIP services include Skype, WhatsApp, and Zoom.

Hence, this statement is true. 

Therefore, Statement I is false but Statement II is True.
