Option A: The author does not assert such a claim. Grammar functions as a tool to structure communication and prevent confusion. However, ensuring sentences remain "simple" is not the "primary purpose" of grammar. Since this statement cannot be inferred from the passage, it is the correct answer.
Option B: Drawing from the limited information provided in the passage, we can infer this 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: Although not explicitly stated, we can grasp the implication behind the term "Grammar Police". The author utilizes this metaphor to represent staunch adherents of grammatical rules, who may swiftly judge and criticize.
Option D: This deduction can be drawn from the passage's excerpt: "... 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..." Here, the author employs an example to demonstrate how a simple combination of a noun and a verb constructs a comprehensive expression.
Therefore, we can deduce all statements except for the one presented in Option A.
So, the correct option is (A): the primary purpose of grammar is to ensure that sentences remain simple.
The task requires identifying a statement that, if false, supports the arguments in the passage about grammar and writing. Let's analyze the options in light of the passage:
Therefore, the statement "Perish the thought that complete sentences necessarily need nouns and verbs!" is the one that, if false, could be seen as supporting the argument in the passage.
