【正确答案】 D

【答案解析】Rhetorical construction; Logical predication; Verb form
This sentence explains the rationale behind a governmental announcement made at some point in the past. The most efficient way to express the meaning of the announcement is to use restrictions as the subject of the clause introduced by that and to use a negative subject (no appreciable increase) and a positive verb in the subordinate clause that follows.
A It makes no sense to say that a hypothetical increase in river level is appreciative. The past tense of the verb resulted in this context does not as clearly express the temporal relationships between the announcement and the other events as would the past perfect had resulted.
B The use of there and the negative verb male the dependent clause unnecessarily wordy and indirect; the relative pronoun that appears to refer nonsensically to level. It makes no sense to say that a hypothetical increase in river level is appreciative.
C By making use of water instead of restrictions the subject of the that clause, this version of the sentence necessitates the use of a wordy and indirect passive infinitive phrase to be restricted. The sentence becomes even more wordy and convoluted with the introduction of an awkward, unidiomatic negative subject {not any appreciable increase) of the dependent clause.
D Correct. The sentence is direct and efficie it, and the past-perfect verb had resulted appropriately expresses the sequence of events.
E The phrase using water... being restricted is wordy and imprecise, and the unidiomatic negative subject (not any appreciable increate) of the dependent clause introduces further indirection and wordiness. The past tense of the verb resulted in this context does not a clearly express the temporal relationships between the announcement and the other events as would the past perfect had resulted.
The correct answer is D.
