KarishmaB GMATNinja1. According to the passage, which of the following is true of plant antiherbivore chemistry?
(A) Changes in a plant's antiherbivore chemistry may affect insect feeding behavior.
(C) A plant's antiherbivore responses assist in combating bacterial infections.
Understanding from passage - plant antiherbivore chemistry relates to plant releasing some substances such as resin when attacked by insects. ( plants initially produced resin in nonspecific chemical responses to insect attack and that, over time, plants evolved that produced resin with specific repellent effects)
Meaning of C - When insect attacks plants and causes bacterial infection, plant will release resin with specific repellent effects to prevent infections.
But resin was released to stop insect attack.
C is incorrect because infection process happens after plant attack and resins was able to repel the insect. So we don't know whether plant antiherbivore chemistry/repelling effect helps in preventing or fighting against infection.
Please help to understand the reason to reject C.
3. The author refers to “bacterial infections” (see line 11) most likely in order to
(E) give an example of how confusion has arisen with regard to the nature of resin
E can be rejected because we don't still don't the reason or nature of resin. What's the meaning of "nature of resin"? Is the author referring to "physiological function" or something else?
Thank you for your help!
