Evaluating Claims, Evidence & Arguments
Reading-time estimate excludes practice. Take the time you need.

Evaluate claims, reasons, evidence, and gaps in an argument.
Read the explanations, try the quick checks, then take the lesson quiz to see what to review next.
An argument offers a claim, supporting evidence, and reasoning that connects them. Evaluation asks whether that connection is strong enough—not whether the conclusion agrees with your preference. A true statement can be irrelevant; a persuasive style can hide weak evidence.
Map claim, reasons and counterclaims
Start by stating exactly what the writer wants accepted. A proposal (“extend library hours”) is not identical to an empirical prediction (“the extension will increase access for shift workers”). Then label the offered evidence and the reasoning that connects it to the claim. An unstated assumption often sits in that connection.
Original example: “The evening survey received 80 requests for later hours, so the library should close two hours later every day.” The survey supports interest among its respondents. Moving to a daily policy additionally assumes that demand is representative, sustained and worth the cost. A counterclaim offers a competing position; a rebuttal responds with reasons or evidence rather than merely repeating the proposal.
Distinguish disagreement from evidence of error. A person may accept that later hours help some residents but oppose the cost. That is a value or priority difference, not necessarily a dispute about the survey count.
