Question 13.

Option A: This can be inferred from "...Must you write complete sentences each time, every time? Perish the thought. If your work consists only of fragments and floating clauses, the Grammar Police aren’t going to come and take you away..." The author presents an illustration to show how a simple combination of a noun and verb forms a complete expression.

Option B: Based on the limited information available from the passage, we can make this inference from "...no group of words can be a sentence, since a sentence is, by definition, a group of words containing a subject (noun) and a predicate (verb)..."

Option C: The author does not make any such claim. Grammar serves as a mechanism to organize communication and avoid confusion. However, the "primary purpose" of grammar is not to ensure that sentences remain "simple". Since we cannot infer this statement from the passage, it is the correct answer.

Option D: Although not explicitly mentioned, we can understand the sentiment behind using the term "Grammar Police". The author is using this as a metaphor for the strong adherents of the grammatic rules (who are perhaps swift to judge and criticize).

Therefore, we can infer all of the statements except for the one in Option C.
