When you’re asked to strengthen or weaken an argument, the focus is on how well the evidence supports the conclusion. The best approach is to examine and influence that link: in a strengthen item, you add information that makes the connection more plausible or robust; in a weaken item, you undermine the connection by exposing flaws in the evidence, assumptions, or reasoning.

That’s why strengthening or weakening the link between conclusion and evidence is the right strategy. Adding more length or detail to the overall argument doesn’t guarantee a stronger connection and can even introduce irrelevant material. Changing the conclusion to a different claim or arguing a new premise creates a separate argument rather than addressing how well the existing evidence supports what’s claimed.
