Short Answer 
Vociferous opinions are expressed with strong conviction, making them difficult to suppress. The best term to describe them is “suppressed,” as it indicates the challenge of stifling such forceful expressions, while other terms like “ignored,” “underestimated,” or “avoided” do not properly reflect their nature.
Step 1: Understand Vociferous Opinions
Vociferous opinions are marked by strong beliefs that are expressed loudly and assertively. These opinions are delivered with conviction, making it clear that the individual holds their views passionately. Recognizing this intensity is crucial in understanding their impact on discussions or debates.
Step 2: Analyze the Correct Option
The correct answer to describe vociferous opinions is suppressed. This term highlights the difficulty in stifling such strong and forceful opinions. Since these expressions are bold, they often resist attempts to downplay or silence them, making “suppressed” the most fitting choice.
Step 3: Review Incorrect Options
It is important to understand why other terms do not fit:
- Ignored: This term focuses on the reception of the opinions rather than their expression.
- Underestimated: While strong beliefs deserve attention, this word fails to capture the nature of vociferousness.
- Avoided: Opinions are labeled vociferous due to their expressive nature, not their evasion.
