Step 1: Understanding the Concept:
This sentence describes the meaning of the word "modern" over time. It states that the term has "always been used broadly." The second part of the sentence should extend or intensify this idea. The structure suggests a continuation of the same trend.
Step 2: Detailed Explanation:
If a term has always been used "broadly," and recent reports show a change, it is logical to assume the broadness has increased. We are looking for a word that means even more broad, vague, or ill-defined.
- (A) precise: This means exact or clearly defined, which is the opposite of "broadly."
- (B) pejorative: This means having a negative connotation, which is unrelated to broadness.
- (C) revisionist: This relates to the re-interpretation of history, not the definition of the word itself.
- (D) acceptable: This is irrelevant to the scope of the word's meaning.
- (E) amorphous: This means lacking a clear shape, structure, or definition. This is a perfect synonym for being extremely broad or ill-defined, intensifying the initial description.
Step 3: Final Answer:
If the term was always broad, and the trend has continued, its meaning has become more "amorphous" (shapeless, undefined).
