Question

historically African elephants have had large ivory tusks for many years poachers have been killing elephants that large tusks so they can sell the ivory which is valuable now many African elephants have small tusks or do not develop tusks at all which of the follow is true

A.The trait of tusk size in elephants has changed over time.

B.Elephants without tusk are more likely to be hunted then elephant with large tusk.

C.Poaching has had no effect on the size of elephants tusks.

D.Elephants without tusks cannot reproduce.

Answer 1

By deducing the choices, it may be seen from the scenario given that elephants with large tusks are more likely to be hunted than those with smaller ones, so B is wrong. Similarly, because of the poachers hunting, the elephants develop smaller tusks thus, C is also wrong. Elephants are mammals, so I don't think the tusk has something to do with the reproduction. We are then left with letter A as our answer.
