113. Visitors to the park have often looked up into the leafy canopy and saw monkeys sleeping on the branches, whose arms and legs hang like socks on a clothesline.

(A) saw monkeys sleeping on the branches, whose arms and legs hang

(B) saw monkeys sleeping on the branches, whose arms and legs were hanging

(C) saw monkeys sleeping on the branches, with arms and legs hanging

(D) seen monkeys sleeping on the branches, with arms and legs hanging（D）

(E) seen monkeys sleeping on the branches, whose arms and legs have hung

Choices A, B, and C use have... saw where have... seen is required. Choices A, B, and E awkwardly separate the relative clause beginning whose arms and legs... from monkeys, the noun it modifies. Choices A and E also confusingly use the present tense hang and the present perfect have hung, respectively; neither verb conveys clearly that, at the time the monkeys were spotted sleeping, their arms and legs were hanging in the manner described. Choice D, the best answer, not only forms a correct and clear sentence by supplying the present perfect verb have... seen, but also solves the problem of the whose... clause by using the appropriately placed adverbial phrase with arms and legs hanging... to modify sleeping.
