Certain rodents bury seeds in shallow underground caches even when food is plentiful, and they rarely recover all the seeds they store. Researchers hypothesize that seed-burying functions not only as food storage but also as a way to promote new plant growth around the rodents’ home areas, thereby boosting their future food supply.
The passage explains that rodents bury seeds as a future storage and also to promote new plant growths to secure their future food requirement.
Which of the following, if true, most strongly supports the hypothesis? Lets analyze statements
(A) Rodents are more likely to bury seeds in areas where plant density is low than in areas with abundant vegetation.
This can be established as rodents store seeds to promote new plants growth and therefore in low vegetation areas they will be burying seeds. Keep thi option
(B) Some of the seeds buried by rodents are occasionally dug up and eaten by other animals.
No hypothesis was made for other animals in passage. So can't be followed. Eliminate
(C) Seeds buried in deep caches are often too far down to germinate.
Passage say they bury at shallow depth it weakens the hypothesis. Eliminate.
(D) Rodents tend to bury more seeds during years when rainfall is scarce.
Can't be followed from passage. Eliminate.
(E) In areas where rodents are absent, most seed dispersal occurs via wind and insects.
Irrelevant and can't be followed from passage. Eliminate
Correct answer is A.
