Which statement best describes the effect of a header that ignores alternate possibilities on an argument's strength?

• A. It strengthens the argument
• B. It has no effect
• C. It slightly clarifies
• D. It weakens the argument

Answer: (D)

Considering alternative possibilities is essential to a strong argument. When you build a case, evaluating other plausible explanations, counterexamples, or competing evidence shows you’ve tested the claim rather than just selected supporting details. If a header ignores these alternate possibilities, the argument appears biased and less convincing because it hasn’t been subjected to the kinds of checks that would challenge or refine it. The claim becomes more vulnerable to counterarguments and easier to undermine with new information. That’s why the best description is that ignoring alternate possibilities weakens the argument. The other options don’t fit because ignoring alternatives doesn’t strengthen or clarify, and it certainly doesn’t leave the argument with no effect; it reduces its persuasiveness by failing to address potential objections.
