A subseasonal weather forecast attempts to predict weather conditions three to four weeks in ______ blank its predictions are therefore

Question

A subseasonal weather forecast attempts to predict weather conditions three to four weeks in blank its predictions are therefore more short-term than those of the seasonal forecast, which attempts to predict the weather more than a month in advance.

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

Accepted Answer

Choice C is the best answer. The clause &ldquo;A subseasonal...advance&rdquo; and the clause &ldquo;its predictions...forecast&rdquo; are both independent clauses, so using a semicolon to separate them is grammatically correct. Choice A is incorrect. This choice creates a run-on sentence error. The clause &ldquo;A subseasonal...advance&rdquo; and the clause &ldquo;its predictions...forecast&rdquo; are both independent clauses, so a comma is not enough to separate them. Choice B is incorrect. This choice creates a run-on sentence error. The clause &ldquo;A subseasonal...advance&rdquo; and the clause &ldquo;its predictions...forecast&rdquo; are both independent clauses, so they need to be separated with specific punctuation (a period, a semi-colon, a colon, a dash, or a comma + a coordinating conjunction). Choice D is incorrect. This choice creates a run-on sentence error. The clause &ldquo;A subseasonal...advance&rdquo; and the clause &ldquo;its predictions...forecast&rdquo; are both independent clauses, so the word &ldquo;and&rdquo; by itself is not enough to separate them. There would need to be a comma before &ldquo;and&rdquo; for this choice to work.
