Question #N318
The scientist’s work, ______ the use of the new instrument, has been praised as a significant advance in the field of astrophysics.
Which choice completes the text so that it conforms to the conventions of Standard English?
A. that involved
B. which involved
C. involving
D. involved
Correct Answer is: B
The correct answer is B. The sentence requires a relative clause, which is a clause that modifies a noun. Choice A is incorrect because a relative clause that begins with *that* should not be used to modify a noun that is the object of a preposition (in this case, the preposition *in*). Choice C is incorrect because a present participle phrase is generally used to modify a noun that is the subject of the sentence, not the object of a preposition. Choice D is incorrect because it creates a fragment. Choice B is correct because it creates a relative clause that modifies the noun *work*.
