Read the passage
1. Option A. discussing the relationship between the size of mammals and the nature of vegetation in their habitats.
Option B is wrong answer as contrasting ecological conditions are only a basis for the discussion regarding mammalian size and vegetation available.
Option C is wrong as, even though the passage implies that some large animals do not require much food, it does not talk about a strict relation as such.
Option D is incorrect as the passage means to stress on size of animals only to throw light on the effect of existing vegetation of an area on mammalian size, and not to discuss size of mammals.
Option A is the most appropriate answer.
2. Option C.
Option A is incorrect as the prejudice itself refers to the reasoning of the biologist.
Option B is partially incorrect because even though it gives a false impression, the prejudice does not imply the animals in Africa but rather in other tropical areas.
Option D is incorrect as the author is clear on the topic that the prejudice is wrong and the passage is written on his idea that it is a false presumption.
Option C is correct as the passage itself states that the prejudice leads to wrong assumptions made by geologists.
Vitiate= spoil or destroy the quality of.
3. Option D.
Option A is incorrect as it is vague and does not specify the real purpose of the comparison.
Option B is incorrect as it does not signify the availability of food. The passage is concerned with mammalian size and vegetation, hence animals as a food source does not concern this passage.
Option C is incorrect as habits of antelopes nd migratory birds have nothing in common.
Option D is correct as the author is conveying the sheer size of the herds through the comparison to the large flocks of migratory birds.
4. Option C.
Option A is incorrect as the popular misconception is that greater the vegetation, greater is the bulk of the animal. This has been disproved in the beginning of the passage by describing an area of less vegetation but having large sized animals.
Now, he author furthers his hypothesis by going into the details of an area with much vegetation but smaller sized mammals. Hence option C is the correct answer.
1. The prejudice that larger quantity of vegetation leads to larger bulk in mammalian size has vitiated the reasoning of geologists.
2. Dr. Smith referred to Africa as a sterile country as it is hardly covered by vegetation, and with the exception of the southern coasts which have some fine forests, the rest of the land is covered in scanty vegetation.
3. The ‘carnage’ referred to by Dr. Smita is the large number of animals that are killed to feed the carnivores in Africa everyday.
4. Darwin’s remark indicates that there is no definitive way at present to compare the respective weights of animals.
5. Darwin suggests that the vegetation in Africa is such that it regenerates very quickly and the amount of vegetation is maintained. Also, larger quadrupeds roam quite far in search of food. This could be the possible reason for the large number of wildlife present compared to the amount of vegetation available.
6. Darwin concludes that among mammalia there exists no direct relation between the bulk of species and the quantity of vegetation in their habitat.
1.Dense (Para 1): Impenetrable.
Dense: closely compacted
Impenetrable: impossible to pass through.
2.Barren ((Para 2): Sterile.
Barren : too poor to produce any vegetation.
Sterile: inability to sustain life.
