Answers:

915). OA - D

OE - The subject of the main clause is visitors, which should be followed by two verbs using the same tense: have looked and have seen. Have does not need to be repeated in the second verb; it is entirely correct simply to let it be understood. The modifying clause whose arms and legs illogically refers to branches, which immediately precedes it, rather than to monkeys. Replacing the clause with the phrase with arms and legs hanging corrects this error.

A - incorrect - Saw is the wrong verb tense; the clause incorrectly modifies branches

B - incorrect - Saw is the wrong verb tense; the clause does not modify monkeys

C - incorrect - Saw is the wrong verb tense

E - incorrect - The clause modifies branches rather than monkeys; have hung is the wrong tense

916). OA - E

OE - This sentence contains a list of three elements, all of which should be parallel. The last element should be preceded by the conjunction and. In this sentence, the last element must be made parallel to the previous two: (1) to revamp computer security procedures, (2) institute new emergency response teams, and (3) create a special nongovernment organization to take charge of computer security planning. Omitting and causes the reader to anticipate still another element in the series when there is none. Using the participle creating not only violates parallelism but also causes misreading since the participial phrase could modify the first part of the sentence. To does not need to be repeated with institute and create because it is understood.

A - incorrect - Creating is not parallel to to revamp and (to understood) institute, and is needed in this series

B - incorrect - Creating violates the parallelism of the previous two elements; and is needed in this series; since the organization does not yet exist, that takes is illogical

C - incorrect - Creating is not parallel to to revamp and (to understood) institute, and is needed in this series; to has the sense of in order to, but for taking is neither precise nor idiomatic

D - incorrect - In the construction create ... to take, the sense of to is in order to; for taking is not idiomatically correct.
