654). (OG 10th Ques no - 81) - OA - B

OE: To establish the clearest comparison between circumstances in 1973 and those in 1984, a separate clause is needed to describe each year. Choices A and C, in failing to use separate clauses, are too elliptical and therefore unclear. Choice A also incorrectly uses and and a semicolon to separate an independent clause and a phrase. Choice D incorrectly separates two independent clauses with a comma; moreover, the placement of in 1984 is awkward and confusing. In choice E, that refers illogically to income, thereby producing the misstatement that income rather than mortgage payments rose to forty-four percent in 1984. Choice B is best; two properly constructed clauses that clearly express the comparison are separated by a semicolon.

A - incorrect - use of semicolon is wrong

of two different things. Moreover, both... as well as ... is redundant: the correct idiom is both x and y.

C - incorrect - the plural verbs acknowledge and attempt do not agree with their singular subject, reduction; also, it is imprecise to characterize a reduction as performing actions such as acknowledging or attempting.

D, E - incorrect - wrongly use a phrase introduced by now with to modify The gyrfalcon. In both choices, the phrase confusingly seems to parallel with
extinction; a new clause with a present tense verb is needed to state what the gyrfalcon's numbers are now.
