Question #38 (incorrect) The Whooping Crane has successfully rebounded from a close brush with extinction; its numbers are now ten times greater than when hunting and habitat destruction pared the population down to a count of fifteen birds in 1941.
(A) extinction; its numbers are now ten times greater than
correct
(B) extinction; its numbers are now ten times more than
your answer
(C) extinction, their numbers now tenfold what they were
(D) extinction, now with tenfold the numbers they had
(E) extinction, now with numbers ten times greater than
ExplanationThis sentence uses a semicolon properly to separate two independent clauses (groups of words that could function on their own as complete sentences). The pronoun its properly refers to the Whopping Crane, and the plural subject numbers agrees with the plural verb are. There aren’t any apparent errors in this sentence.
The only difference B presents is more versus greater. Idiomatically, a comparison between countable quantities (like numbers of whooping cranes) should be expressed using greater, not more.
Choices C and D incorrectly use the plural pronouns their and they to refer to the singular noun the Whooping Crane.
The prepositional phrases with tenfold... and with numbers... in choices D and E are misplaced; each seems to modify extinction.
Choice A is correct. |
