文章:

Line Carotenoids, a family of natural pigments, form
an important part of the colorful signals used by
many animals. Animals acquire carotenoids either
directly (from the plants and algae that produce
(5) them) or indirectly (by eating insects) and store them
in a variety of tissues. Studies of several animal
species have shown that when choosing mates,
females prefer males with brighter carotenoid-based
coloration. Owens and Olson hypothesize that the
(10) presence of carotenoids, as signaled by coloration,
would be meaningful in the context of mate selection
if carotenoids were either rare or required for
health. The conventional view is that carotenoids
are meaningful because they are rare: healthier
(15) males can forage for more of the pigments than
can their inferior counterparts. Although this may be
true, there is growing evidence that carotenoids are
meaningful also because they are required: they are
used by the immune system and for detoxification
(20) processes that are important for maintaining health.
It may be that males can use scarce carotenoids
either for immune defense and detoxification or for
attracting females. Males that are more susceptible
to disease and parasites will have to use their
(25) carotenoids to boost their immune systems, whereas
males that are genetically resistant will use fewer
carotenoids for fighting disease and will advertise
this by using the pigments for flashy display instead.

题目:

The idea that carotenoid-based coloration is significant partly because carotenoids are required for health suggests that a lack of bright coloration in a male is most likely to indicate which of the following?

选项:

A、Inefficient detoxification processes
B、Immunity to parasite infestation
C、Low genetic resistance to disease
D、Lack of interest in mating
E、Lack of carotenoid-storing tissues

答案:

C

提问:

C为什么是对的呢?这道题我错选了D 原文中第26行不是说genetically resistant的males会用更少的catoteniods吗?

提问:

这一题留下了AC两个答案,本来想选C,但是心里放不下A,觉得A没有错,C里面有一个限定词是genetic,我觉得原文没有说这种对disease的resistance就是基因性的,所以C有问题,排除法选了A,想请问一下是怎么清晰快速的排除A答案的呢?谢谢老师!
