Which choice completes the text so that it conforms to the conventions of Standard English?
A
weightlessness
B
weightlessness which
C
weightlessness,
D
weightlessness;
Explanation
Correct answer: D.
Choice D is the best answer. The convention being tested is the use of punctuation within a sentence. This choice uses a semicolon in a conventional way to join the first main clause ("The Limón…weightlessness") and the second main clause ("dancers…jump").
Why the other choices are wrong
Choice A
Choice A is incorrect because it results in a run-on sentence. The two main clauses are fused without punctuation and/or a conjunction.
Choice B
Choice B is incorrect. The relative pronoun "which" can’t be used in this way to join two main clauses.
Choice C
Choice C is incorrect because it results in a comma splice. Without a conjunction following it, a comma can’t be used in this way to join two main clauses.
