Either food scarcity or excessive hunting can threaten a population of animals. If the groupfaces food scarcity,individuals in the groupwill reach reproductive maturity later than otherwise. If the group faces excessive hunting,individuals that reach reproductive maturity earlier will come to predominate. Therefore, it should be possible to determine whether prehistoric mastodons became extinct because of food scarcity or human hunting, since thereare fossilized mastodon remains from both before and after mastodon populations declined, and__.
(A) there are more fossilized mastodon remains from the period before mastodon populations began to
decline than from after that period
(8) the average age at which mastodons from a given period reached reproductive maturity can be
established from their fossilized remains
(e) it can be accurately estimated from fossilized remains when mastodons became extinct
(D) it is not known when humans first began hunting mastodons
(E) climate changes may have gradually reduced thefood avai lable to mastodons
Please the question as well as the options
