2,Whena caterpillar emerges from the egg on a tree branch, it immediately climbsupward until it finds a leaf bud to eat. Biologists thought that this behavior displayed an innate tendency tomove in the direction opposite to the pull of gravity. In a recent experiment, a strong light sourcewas placed at the bottom of a tree, and caterpillars, after hatching, climbeddownward.

If they laid too many eggs in a host egg, thedeveloping wasp larvae would compete with each other to the death for nutrientsand space. If too few eggs were laid,portions of the host egg would decay, killing the wasp larvae.

Which of the following conclusions can properly be drawnfrom the information above?

(A)The size of the smallest host egg that a wasp could theoretically parasitizecan be determined from the wasp's egg-laying behavior.

Bible解释（标白如下）

This is an intimidating problem at first glance. The terminology is complex and
the problem appears to be based on difficult philosophical principles. First,
analyze the structure of the argument:
Premise: If something would have been justifiably regretted if it had
occurred, then it is something that one should not have
desired in the first place.
Conclusion: Many forgone pleasures should not have been desired in the
first place.
Second, use the three steps for mechanistically solving Justify questions as
described in this section.
1. Any “new” or “rogue” element in the conclusion will appear in the
correct answer.
“Many forgone pleasures” is a new element that appears only in the
conclusion. Only answer choices (B), (C), and (D) contain “forgone
pleasures,” and only answer choice (D) contains “many.” Thus, if forced
to make a quick decision, answer choice (D) would be the best selection
at this point in our analysis. And, fortunately, the technique is so
powerful that this analysis does indeed yield the correct answer.
Regardless, let’s continue.
2. Elements that are common to the conclusion and at least one premise, or
to two premises, normally do not appear in the correct answer.
“Should not have (been) desired in the first place” appears in both the
premise and the conclusion. This element is not likely to appear in the
correct answer choice.
3. Elements that appear in the premises but not the conclusion normally
appear in the correct answer.
“Justifiably regretted” appears in the premise but not the conclusion.
Only answer choices (B) and (D) contain “justifiably regretted.”
Once you become used to examining the elements of the argument, the analysis
above can be made very quickly. The method also correctly reveals answer
choice (D) as correct with a minimum of effort.
