What is the approach here:

Scientists have modifi ed feed corn genetically, increasing its resistance to insect pests. Farmers who tried out
the genetically modifi ed corn last season applied less insecticide to their corn fi elds and still got yields
comparable to those they would have gotten with ordinary corn. Ordinary corn seed, however, costs less,
and what these farmers saved on insecticide rarely exceeded their extra costs for seed. Therefore, for most
feed-corn farmers, switching to genetically modifi ed seed would be unlikely to increase profi ts.
Which of the following would it be most useful to know in order to evaluate the argument?
(A) Whether there are insect pests that sometimes reduce feed-corn yields, but against which commonly used
insecticides and the genetic modifi cation are equally ineffective
(B) Whether the price that farmers receive for feed corn has remained steady over the past few years
(C) Whether the insecticides typically used on feed corn tend to be more expensive than insecticides typically
used on other crops
(D) Whether most of the farmers who tried the genetically modifi ed corn last season applied more insecticide
than was actually necessary
(E) Whether, for most farmers who plant feed corn, it is their most profi table crop

The answer to this question is D

To solve such kind of questions use a simple strategy
For each option check whether an answer(Yes or No) affects the argument
A>Even if there are insects that render both methods ineffective doesn't change anything
B>Whether the price received has remained constant or fluctuated doesn't affect the comparison
C>Other Crops are out of scope
D>Yes, If the farmers used more insecticide in case of genetically modified crops than was required suggests that the observation in the argument was wrong and that more money could be saved making Genetically Modified Crops Cost-Effective.

It has to be D

Approach here: Anything whose answer to yes/no changes the inclination will be the answer. If farmers applied more instecticides then farmers could have made more profit.
Premise: If you like my post
Conclusion : Press the Thanks Button ;)

the savings have to be from lesser usage of insecticides,as the new seeds are costlier.

D nails this by hitting the exact reason.
