The correct answer is Option 4.

Key Points

• Indirect Speech: His angry mother jeered and asked whether he supposed that he knew better than his own father.
• Key Conversions:
• "whether he supposed that he knew" becomes "Do you suppose you know"
• Indirect question "whether he supposed" is converted to direct question "Do you suppose."
• Pronoun "he" is changed to "you" to match direct speech.
• Verb "knew" is changed to "know" to match the present tense in direct questions.
• "his own father" remains "your own father"
• Possessive pronoun "his" is converted to "your" to match the direct speech pronoun change.
• Reporting verb:
• Indirect: "jeered and asked"
• Converted to: "jeered," maintaining the mocking tone.
• Punctuation and Format:
• Direct speech is enclosed in quotation marks.
• Starts with a capital letter "Do" and ends with a question mark "?".
• Reporting clause follows the quoted speech, starting with a lowercase letter after the comma.

Therefore, the correct answer is Option 4.

Correct Sentence: "“Do you suppose you know better than your own father?” jeered his angry mother."

The correct answer is "SPRQ".

Key Points

• A logical follow-up to S1 is to continue the timeline of human advancements.
• S: Sentence S does this by introducing the next big evolutionary steps in the timeline, such as the acquisition of writing and agriculture.
• P: After establishing that man has had writing and agriculture for the times mentioned in S, sentence P speaks about the advent of science. This maintains the chronological sequence of historical developments.
• R: Once the timeline has introduced the rise of science and its duration in human history, sentence R then details the impact of science in that brief period - "it has proved itself an incredibly powerful revolutionary face."
• Q: Following up on the observation made in R about the immense impact of science, sentence Q projects into the future and ponders on ongoing and potential transformations that science will bring in human life.

Therefore, the correct answer is "option 2".

Complete Paragraph:  Man has existed for about a million years. He has possessed writing for about 6,000 years, agriculture somewhat longer, but perhaps not much longer. Science, as a dominant factor in determining the beliefs of educated men, has existed for about 300 years; as a source of economic technique, for about 150 years. In this brief period, it has proved itself an incredibly powerful revolutionary face. When we consider how recently it has risen to power, we find ourselves forced to believe that we are at the very beginning of its work in transforming human life. What are future effects, will be a matter of conjecture, but possibly a study of its effects hitherto may make the conjecture a little less hazardous.

​Therefore, the correct answer is "Option 3".

The correct answer is Option 1.

Key Points

• The paragraph begins by introducing the central vision of growing up and how it involves using our senses and brains to become more aware.
• Sentence Q follows S1 as it explains how man differs from all other animals in this aspect:
• "In this, man differs from all other animals."
• Sentence P follows as it elaborates on the capabilities of man:
• "Not only does he have a memory but he is able to think and reason."
• Sentence S comes next as it describes how man uses experience to plan actions:
• "That is to say, he is able to plan what he is going to do in the light of his experience before he does it."
• Sentence R follows as it talks about the importance of thinking before acting:
• "Before we spray our roadside plants or turn sewage into our rivers, we should pause to think what the results of our actions are likely to be."
• The correct sequence is QPSR.

Coherent paragraph after rearrangement:

"Growing up means not only getting larger but also using our senses and our brains to become more aware of the things around us. In this, man differs from all other animals. Not only does he have a memory but he is able to think and reason. That is to say, he is able to plan what he is going to do in the light of his experience before he does it. Before we spray our roadside plants or turn sewage into our rivers, we should pause to think what the results of our actions are likely to be. In other words, we must develop and use our ability to reason, because the destruction or the preservation of the places in which we live depends upon us."

The correct answer is "No error".

Key Points

• The phrase "The manager was pleased" functions as the subject and predicate of the sentence. It correctly conveys the subject ("The manager") and the action done by the subject ("was pleased").
• In "with the quality of work" phrase**, "with"** is a preposition that describes what the manager was pleased about, and it's used correctly here. "The quality of work" acts as the object of the preposition and is used correctly to point out exactly what the manager was pleased with.
• "submitted by Jennifer" correctly uses the past participle "submitted" to indicate the action taken by Jennifer. The proposition "by" introduces Jennifer as the person responsible for the work.

Therefore, the correct answer is "Option 2".

The correct answer is "PSRQ".

• The first sentence (S1) sets a historic context and describes the high child mortality rate in the eighteenth century.
• P: Sentence P is a logical follow-up because it refers to the beginning of the nineteenth century when an improvement occurred (vaccination started to be used), thus suggesting a change in the situation.
• S: The sentence S naturally follows P because it suggests that the improvement mentioned in P (due to vaccination) "has continued ever since and is still continuing."
• R: Sentence R provides statistics from the 20^th century that illustrate the continuing decrease in infant mortality rates already referred to in S. This represents further proof of the ongoing improvement.
• Q: Sentence Q presents the overall death rate in 1948, and claims that it was the lowest ever at that time. This specific statistical detail further strengthens the argument about the decline in mortality, serving as a strong prelude to the concluding sentence (S6).

Therefore, the correct answer is "Option 1".

Complete Paragraph: In the eighteenth century people expected most of their children to die before they were grown up. Improvement began at the beginning of the nineteenth century, chiefly owing to vaccination. It has continued ever since and is still continuing. In 1920 the infant mortality in England and Wales was 80 per thousand, in 1948 it was 34 per thousand. The general death rate in 1948 (10.8) was the lowest ever recorded till that date. There is no obvious limit to the improvement of health that can be brought about by medicine.

The correct answer is "Misnomer".

Key Points

• The term "misnomer" literally means to misname, or a name or term that is inappropriate or does not reflect the actual nature of the entity it denotes.
• "Mis-" is a prefix derived from Latin, and it usually indicates an ill-judged, wrong, or negatively affecting condition.
• "-nomer" comes from the Latin "nominare" which means "to name."
• For Example - Calling Greenland 'green' is a misnomer, seeing as much of it is covered in ice.

Therefore, the correct answer is "Option 4".

The correct answer is "badc".

Key Points

• Sentence B follows the first as they both discuss how hunger is often unseen or ignored until dramatic incidents occur that thrust it into the public eye.
• Sentence A extends the idea from sentence b by elaborating on the severity and pervasiveness of the issue of chronic hunger.
• Sentence D picks up from sentence a, further expanding on the idea of chronic hunger as a prevalent issue affecting millions of people.
• Sentence C follows naturally from sentence d by giving specific examples of the people who are affected.
• Sentence 6 provides further specifics on the disenfranchised communities mentioned in sentence c.

The correct answer is "Option 2".

Complete Paragraph: Hunger lurks unseen in every village and city of our country. Yet it surfaces into public consciousness only transiently, in moments when there are troubling media reports of starvation deaths. What goes unrecognised is that death by starvation is only the most dramatic manifestation of a much more invisible malaise - of pervasive, stubborn, chronic hunger. And, that there are millions of forgotten people in India who live routinely at the very edge of survival, with hunger as a way of everyday life. Among these are entire communities, utterly disenfranchised and asset less. Like the Musahaars, a proud and savagely oppressed Dalit community in Bihar and Uttar Pradesh, who own not even the land on which their tenuous homesteads are built.

The correct answer is Lysosomes

Key Points

Lysosomes are called suicidal bags of the cell.

• This is because the lysosomes are organelles that digest materials taken up by the cell from the outside.
• If the lysosomes burst by any chance, the digestive enzyme leaks into the cell's insides.
• After that these enzymes digest the parts of the cell as well.

Additional Information

• Dictyosomes (Golgi Apparatus):
• Organelles involved in packaging, modifying, and transporting proteins and lipids within the cell.
• Phagosomes:
• Membrane-bound vesicles formed during phagocytosis, where cells engulf foreign particles or microorganisms for degradation.
• ​Ribosomes:
• Cellular organelles responsible for protein synthesis.

The correct answer is Chloroplasts

Key Points

• The chloroplast is an organelle that contains the photosynthetic pigment chlorophyll that captures sunlight and converts it into useful energy, thereby, releasing oxygen from water.
• Chloroplasts are found in all green plants and algae.
• They are the food producers of plants.
• These are found in the guard cells located in the leaves of the plants.
• They contain a high concentration of chlorophyll that traps sunlight.
• This cell organelle is not present in animal cells.

Explanation-

• RuBP enzyme is required for Photosynthesis.
• RuBP enzyme is the most abundant enzyme present in plants.
• It catalyzes the carboxylation reaction between carbon dioxide and Ribulose Bisphosphate.
• It is used in the Calvin cycle of Photosynthesis.
• Each molecule of carbon dioxide is attached to a five-carbon sugar called ribulose bisphosphate (RuBP).
• Rubisco is the most abundant protein found in chloroplasts.

Additional Information

• Lichens:
• Lichens are symbiotic organisms composed of a fungus and a photosynthetic partner (either algae or cyanobacteria).
• While the photosynthetic partner may contain chlorophyll, it is not specifically present in lichens themselves.
• Algae:
• Chlorophyll is present in algae, a diverse group of photosynthetic organisms ranging from single-celled microalgae to large seaweeds.
• Like plants, algae use chlorophyll to capture light energy for photosynthesis.
• Fungi:
• Fungi are non-photosynthetic organisms that obtain nutrients through absorption.
• They do not contain chlorophyll and therefore cannot photosynthesize like plants and algae.

The Correct answer is The image is smaller in size by a factor of 0.20.

Key Points

• The mirror described in the question is a convex mirror, which is evident from the mention of a rear-view mirror.
• For a convex mirror, the focal length (f) is negative and can be calculated as f = R/2, where R is the radius of curvature.
• Given that the radius of curvature (R) is 4.00 m, the focal length would be -2.00 m.
• The mirror formula is given by 1/f = 1/v + 1/u, where u is the object distance and v is the image distance.
• Given the object distance u = -6.00 m (object distances are taken as negative in the mirror formula for convex mirrors), solving for v gives us -1.5 m (indicating the image is formed at 1.5 m behind the mirror).
• The magnification (m) of a convex mirror is given by m = v/u.
• Substituting the values, we get m = (-1.5)/(-6.0) = 0.25, which means the image is smaller by a factor of 0.25, not 0.20.

 Additional Information

• The image will be formed at a distance of 1.5 m at the back of the mirror.
• This is correct and is calculated using the mirror formula.
• Convex mirrors always form virtual, diminished, and erect images behind the mirror.
• The image is virtual.
• This is a characteristic of images formed by convex mirrors.
• Virtual images cannot be obtained on a screen.
• The mirror is convex.
• Rear-view mirrors in automobiles are typically convex mirrors.
• They provide a wider field of view compared to plane mirrors.

The Correct answer is Absolute scale.

Key Points

• The Absolute scale is also known as the Kelvin scale.
• This scale is a thermodynamic temperature scale where absolute zero is defined as the point at which all thermal motion ceases.
• Absolute zero is 0 K, which is equivalent to -273.15°C.
• The Kelvin scale is used extensively in scientific measurements because it is an absolute scale based on absolute zero.
• In the Kelvin scale, temperature increments correspond directly to those on the Celsius scale, making it easy to convert between the two.

 Additional Information

• Celsius scale
• The Celsius scale is a temperature scale used in most of the world, where water freezes at 0°C and boils at 100°C at standard atmospheric pressure.
• It is also known as the centigrade scale.

• It was proposed by Daniel Gabriel Fahrenheit in 1724.
• Richter scale
• The Richter scale is used to measure the magnitude of earthquakes.
• It was developed in 1935 by Charles F. Richter.
• It is a logarithmic scale, meaning each whole number increase represents a tenfold increase in measured amplitude.

The correct answer is Vitamin D

Key Points

• Vitamin D is produced in the human body by exposure to sunlight.
• Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and multiple other biological effects.
• In humans, the most important compounds in this group are vitamin D3 (also known as cholecalciferol) and vitamin D2 (ergocalciferol).
• The major natural source of the vitamin is the synthesis of cholecalciferol in the skin from cholesterol through a chemical reaction that is dependent on sun exposure (specifically UVB radiation).
• The sun's ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis to occur.
• Dietary recommendations typically assume that all of a person's vitamin D is taken by mouth, as sun exposure in the population is variable and recommendations about the amount of sun exposure that is safe are uncertain in view of the skin cancer risk**.**​

Additional Information

• Vitamin K:
• Essential for blood clotting and bone health.
• Found in foods such as leafy green vegetables (e.g., spinach, kale), broccoli, Brussels sprouts, and some animal products.
• Vitamin A:

• Found in a wide range of foods including meat, fish, poultry, dairy products, eggs, grains, fruits, and vegetables.

The correct answer is Reduce, Reuse, Recycle

Key Points The 'Reduce', 'Reuse' and 'Recycle' elements are referred to as the '3 R's'.

• Reducing - Try to reduce the amount of waste produced, as this is the best way to help the environment.
• Reusing – New methods must be applied for reusing all the old stuff.
• Recycling- This enables the materials which are thrown away to be used again by making them into new products.

The correct answer is Neem leaves

Key Points

• Organic farming: It is defined as a farming system that uses minimal or no chemicals such as fertilizers, herbicides, and pesticides and instead relies heavily on organic manures, recycled farm wastes, and bio-agents, as well as healthy cropping systems.
• Biopesticides are pesticides derived from natural elements such as plants, animals, microbes, and minerals.
• They are unique in that they do not affect the plant or other species except the target organism.
• Neem leaves are used as biopesticides in organic farming because of the presence of multiple limonoids in neem plant extracts and oil, which not only provides a sustainable pest control mechanism but also prevents plant disease resistance from various synthetic insecticides
• Neem plant-based insecticides have been the most accepted bio-pesticides among the various herbs.

Additional Information 

Different techniques followed in organic farming are - 

• Catch Crop: A catch crop is a fast-growing crop that is planted in between main crop plantings. It allows better use of available growing space and prevents mineral runoff.
• Mixed Crop: Instead of one crop, two or more crops are grown on the same piece of land during the same growing season.
• ​Manure: Manure is purely organic and is used in agriculture. Animal faeces make up the majority of manure and other sources include compost that is together used to make manure.

The correct answer is Protein

Key Points

• Proteins are made up of molecules called amino acids and are found in all living organisms.
• Each amino acid contains four elements: hydrogen, oxygen, nitrogen, and carbon, as well as sulfur in some cases.
• Proteins are macromolecules or massive biomolecules made up of one or more long chains of amino acid residues.
• Proteins play a variety of roles in animals, including catalyzing metabolic reactions, DNA replication, reacting to stimuli, giving cells and organisms structure, and transporting molecules from one place to another.

Additional Information

• A polypeptide is a linear sequence of amino acid residues.
• At least one long polypeptide can be found in a protein. Antoine Fourcroy and others identified proteins as a distinct class of biological molecules in the eighteenth century, based on their ability to coagulate or flocculate when exposed to heat or acid.

• Pumpkin, cucumber, watermelon, bitter gourd, etc are all Zaid types of crops.

The correct answer is Lysosomes

Key Points 

• Lysosomes are called “Suicidal Bags” because whenever a cell is damaged the lysosome bursts releasing all the digestive enzymes and thus killing the cell as well as itself.
• The lysosome is a membrane-bound organelle that contains an array of enzymes, capable of breaking down all types of biomolecules like proteins, carbohydrates, and lipids.
• The lysosomes also act as the waste disposal system of the cell by digesting unwanted materials.

The Correct answer is Gills.

Key Points

• Gills are specialized organs used by fishes to extract oxygen from water.
• They are highly efficient in exchanging gases, allowing fishes to live and thrive in aquatic environments.
• Gills are made up of numerous gill filaments which increase the surface area for gas exchange.
• Water passes over the gill membranes, where oxygen is absorbed into the bloodstream and carbon dioxide is expelled.
• They allow fishes to extract up to 85% of the oxygen from the water they pass through their gills.

 Additional Information

• Liver
• The liver in fishes is involved in various metabolic processes, including detoxification and storage of glycogen and fat.
• It is not specifically an adaptation to an aquatic habitat but a general metabolic organ.
• Lungs
• Lungs are found in terrestrial animals and some amphibians, adapted for breathing air.
• Most fishes do not possess lungs; however, some species like lungfishes have lungs to breathe air.
• Teeth
• Teeth in fishes are used for capturing prey and mechanical digestion.
• While important for feeding, teeth are not a unique adaptation to aquatic environments.

The correct answer is 1 Poise.

Key Points

• Viscosity is a measure of a fluid's resistance to deformation at a given rate, such as flow.
• In simple terms, it describes the internal friction of a moving fluid.
• The unit of viscosity in the CGS (centimeter-gram-second) system is the Poise.
• A fluid's viscosity remains the same whether it is in motion or at rest, unless there are changes in temperature or pressure.
• Therefore, a fluid with a viscosity of 1 Poise in motion will also have a viscosity of 1 Poise when at rest.
• Viscosity is an important property in various applications such as in lubricants, hydraulic fluids, and food products.

 Additional Information

• Viscosity
• Viscosity can be affected by temperature and pressure. Generally, as temperature increases, viscosity decreases for liquids and increases for gases.
• In industrial applications, viscosity measurement is crucial for ensuring the quality and performance of products.
• Common instruments used to measure viscosity include viscometers and rheometers.

The correct answer is 1 mole of sodium atoms.

Key Points

• 1 mole of sodium atoms is the heaviest among the given options.

• It is vital for all known forms of life and is the most abundant substance on Earth's surface.

The correct answer is Pupa

Key Points

• In the pupa stage, a weave is netted around by the silkworm to hold itself. After that it swings its head, spinning a fiber made of a protein and becomes a silk fiber.
• Several caterpillars form a protective layer around the pupa and this covering is known as the cocoon.
• Lifecycle stage imago:
• The term "imago" is used to describe an insect's adult stage.
• The larvae are kept in clean bamboo trays along with freshly chopped mulberry leaves.
• After 25 to 30 days, the caterpillars stop eating and move to a tiny chamber of bamboo in the tray to spin cocoons.
• Small racks or twigs may be provided in the trays to which cocoons get attached.
• The process of silk production begins during the larval stage when the silkworm feeds on mulberry leaves and produces silk threads from specialized glands located in its head.
• These silk threads are used to construct a protective cocoon around the pupa.
• Inside the cocoon, the silkworm undergoes metamorphosis and transforms into a moth, known as the imago stage.
• However, for silk production, the cocoons are typically harvested before the moth emerges from the pupa, as the emerging moth would break the silk threads.

Additional Information

• Egg:
• A female silk moth lays hundreds of eggs at a time.
• The eggs are warmed to a suitable temperature for the larvae to hatch from the eggs.
• Pupa:
• The silkworm weaves a net around itself to hold itself during the pupa stage.
• Cocoon:
• The cocoon is the collective name for the protective layer that several caterpillars create around the pupa.

The correct answer is Ascariasis.
