答案E
解析 Logical predication; Idiom
The predicate numbered must have its logically correct subject, which is wolves. Although the wolf can be used to refer collectively to wolves as a category, the noun should be plural in this case since the sentence refers to numbers of them and since agreement is needed between the noun and the plural pronoun them. Given the plural subject, the verb in the independent clause should be have declined. The object of decline to should be a word or phrase naming a number or estimated number (e.g., a phrase such as an estimated 200,000), no the phrase an estimate.
A The subject of the main clause (it) seems to supply the subject of numbering, so the latter does not have its correct logical subject, which should be a word or phrase referring to wolves.
B The wolf cannot correctly be taken as the subject of numbering, as it is singular and in disagreement with them occurring later in the sentence.
C The wolf cannot correctly be taken as the subject of numbering, as it is singular and disagrees with the later them; also, a decline is strictly speaking to a number, not to an estimate.
D Although wolves is a correct subject for numbering, a decline should be to a number, not to an estimate.
E Correct. Wolves is a proper subject for numbering and agrees with the later them. The decline is correctly said to be to a number, an estimated 200,000.
The correct answer is E.
