In the material, which term appears as a heading that introduces subsequent 'Answer' blocks?

• A. Montesquieu
• B. Answer
• C. 20 January 2021
• D. Last six American president

Answer: (B)

Recognizing formatting conventions: the heading that introduces the solution blocks is the word "Answer." It clearly signals that what follows is the response or solution to the item. The other options—a surname, a date, or a phrase about presidents—don’t serve as a standard heading for answer blocks, so they wouldn’t introduce the subsequent solution content.
