不知道是不是由于最强或最弱(新东方old book section 13)

各位NN麻烦来看看亚

11. Caterpillars of all species produce an identical

hormone called "juvenile hormone" that maintains

feeding behavior. Only when a caterpillar has grown to

the right size for pupation to take place does a special

enzyme halt the production of juvenile hormone. This

enzyme can be synthesized and will, on being ingested

by immature caterpillars, kill them by stopping them

from feeding.

Which of the following, if true, most strongly supports

the view that it would not be advisable to try to eradi-

cate agricultural pests that go through a caterpillar

stage by spraying croplands with the enzyme

mentioned above?

(A) Most species of caterpillar are subject to some

‍natural predation.

(B) Many agricultural pests do not go through a cater-

‍pillar stage.

(C) Many agriculturally beneficial insects go through

‍a caterpillar stage.

(D) Since caterpillars of different species emerge at

‍different times, several sprayings would be

‍necessary.

(E) Although the enzyme has been synthesized in the

‍laboratory, no large-scale production facilities

‍exist as yet.

key is C.但是为什么B不对，是不是这就是传说中的most strongly support的问题，意思是说几个答案都可以的情况下要选最强的一个。

但是有时候我发现这个最强的或最弱的很难区分嘛

选项中永远不可能出现多个支持或削弱的选项，也不可能有最强或最弱的问题存在。

B错的原因是因为无关。原文讨论的是经过幼虫阶段的害虫， 不经过的不再讨论之列。注意问题：try to eradicate agricultural pests that go through a caterpillar stage
