答案
D
解析
Verb form; Logical predication; Rhetorical construction
This sentence presents conditions that are followed by an unexpected outcome: a delayed announcement of the discovery of a pulsar. A compound sentence using a coordinating conjunction but is an effective way to present the conditions of the first pulsar sighting and then information about the subsequent announcement of the discovery. The sentence must clarify that it is not about the first pulsar, but the first pulsar... to be sighted. The verbs in the sentence must all be in past tense; using a past-perfect verb to present information about the announcement of the discovery indicates that this announcement illogically took place before the pulsar was first sighted.
A The subject of the opening dependent clause is pulsar, and the verb is was. The clause needs to indicate not just that the pulsar existed but that it was observed by Bell; the past-perfect verb tense is inappropriate in the concluding clause.
B The opening participial phrase functions as an adjective, but it has no logical noun or noun phrase to attach to; Bell herself was not announced in 1968.
C Grammatically, the opening participial phrase describes the first noun that follows, but it makes no sense to say that the discovery of the pulsar was observed; discovery of the first sighted pulsar is also imprecise; one does not discover a first sighting.
D Correct. The sentence presents the sequence of events clearly and in the past tense.
E This sentence presents events in a way that is confusing; as a conjunction, while indicates simultaneous events, but this sentence is about events that occurred in a sequence.
The correct answer is D.
