Question 4: A. Yes, it's true that we drive a couple hundred species to extinction every day, but there are tens of millions --hundreds of millions--between us and catastrophe.

B. But of course this constitutes a fundamental misunderstanding of biological realities. What we've done in actual fact is make ourselves the chief agent of natural selection in these enemy species.

C. Generation after generation, we are in effect producing a population of insects more and more resistant to our insecticides. If we wanted to produce such insects, this would be exactly the way to go about it!

D. Very simply, all too often we've acted as though we could make species of small, fast breeding creatures extinct down to the very last member, the way we might do with elephants or pandas.

E. Our insecticide hasn�t killed off every last member of the targeted species in a given field, but the 80% that are most susceptible to the deadly effect of the insecticide, leaving alive as breeding stock for the next generation the 20% that was less susceptible.

1. A
2. B

4. D
5. E

Explanatory Answer

Method of solving this CAT Question from Sentence Elimination:

Looking at the sentences, we see that EC is a clear link: E explains what insecticides do and C, the effect of this. These sentences highlight the flaw in the logic of using insecticides to eliminate insects. This, in turn, relates to B. EC explains what making ourselves "the chief agent of natural selection in these enemy species"(stated in B) means. So, B goes before EC. We now have to choose between A and D and see which one relates to "a fundamental misunderstanding of biological realities" that B mentions. Both A and D are about our misunderstanding of biological realities. But while A is general statement, the reference to "small, fast breeding creatures" in D could relate to insects. DBEC is a cogent paragraph. Option A is the one to be eliminated.
