Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation
Choice D is the best answer. The convention being tested is the coordination of main clauses within a sentence. This choice correctly uses a comma and the coordinating conjunction "but" to join the first main clause ("At...world") and the second main clause ("the...longer").
Choice A is incorrect because when coordinating two main clauses such as these, it’s conventional to use a comma before the coordinating conjunction. Choice B is incorrect because a comma isn’t needed after the conjunction "but." 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.
