The question is about strengthening an argument by making the reasoning more solid. Adding new evidence that supports the conclusion directly increases the reasons why the conclusion should be accepted. It broadens or reinforces the empirical or logical basis for the claim. Clarifying ambiguous terms helps ensure everyone understands exactly what is being claimed and how the evidence connects to the conclusion, which removes potential gaps in interpretation that could weaken the argument. Replacing a weak premise with a stronger, more reliable one improves the logical foundation so the conclusion follows more convincingly from the premises.

An unrelated example doesn’t contribute to the strength of the argument because it doesn’t affect the connection between the premises and the conclusion. It can distract or mislead, since it illustrates a different point and leaves the core reasoning unchanged.
