Within Earth’s biomes, there are four main types of desert: arid, semiarid, coastal, and cold. The roughly is classified as an arid desert. Which choice completes the text so that it conforms to the conventions of Standard English?

The correct answer is C. Choice C is the best answer. The convention being tested is the use of punctuation between a modifier and a noun and also between a subject and a verb. No punctuation is needed when, as in this case, a modifying phrase (“roughly 200,000 km²”) precedes the noun phrase it modifies (“Puntland Desert”) to form the subject of the sentence. Additionally, no punctuation is needed between the subject (“The roughly...Desert”) and the main verb (“is classified”).
