Question 12.

The author begins by highlighting the necessity for a set of codes (enabled by grammar) to organize communication and avoid confusion. He then proceeds to present supplementary arguments in this regard (elements associated with rhetoric and its specialists) and emphasizes how even proper, intentional simplification can be attained only through a firm grasp of the rudiments of grammar. Therefore, it can be observed that grammar is the focal point here and the correct choice should definitely align with this. Option B aptly captures the main concern raised in the passage. Options A and C fail to include the idea revolving around grammar and instead focuses on the additives. Option D is close; however, the mention of nouns and verbs is with the intention to supplement the idea highlighted in B. These simply serve as an illustration to emphasize the significance of grammar. Thus, between the two options B and D, Option B is the suitable choice.
