Which choice completes the text so that it conforms to the conventions of Standard English?

Accepted Answer

Choice C 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 measurement...moved") and the second main clause ("for example...second"). Choice A is incorrect because it results in a comma splice. Without a coordinating conjunction, a comma can&rsquo;t be used in this way to join the two main clauses ("The measurement...moved" and "for example...second"). Choice B is incorrect because it results in a comma splice. Without a conjunction following it, a comma can&rsquo;t be used in this way to join the two main clauses ("The measurement...moved" and "one unit...second"). Choice D is incorrect because it results in a run-on sentence. The two main clauses ("The measurement...moved" and "one unit...second") are fused without punctuation and/or a conjunction.
