Conservationist: The population of a certain wildflower is so small that the species is headed for extinction. However, this wildflower can cross-pollinate with a closely related domesticated daisy, producing viable seeds. Such cross-pollination could result in a significant population of wildflower-daisy hybrids. The daisy should therefore be introduced into the wildflower’s range, since although the hybrid would differ markedly from the wildflower, hybridization is the only means of preventing total loss of the wildflower in its range.
. Which one of the following is an assumption on which the conservationist’s reasoning depends?
(A) The wildflower currently reproduces only by forming seeds.
(B) The domesticated daisy was bred from wild plants that once grew in the wildflower’s range.
(C) Increasing the population of the wildflower will also expand its range.
(D) Wildflower-daisy hybrids will be able to reproduce.
(E) The domesticated daisy will cross-pollinate with any daisy like plant.
