2-Minute Revision

An argument moves from reasons to a conclusion. A relevant option affects that movement. Lower defect counts do not establish better quality if the production denominator falls faster. More digital borrowing does not establish that print should disappear if users cannot access the substitute. New evidence may weaken a conclusion without disproving it. Ask which link changes, not whether the option sounds favourable.

5-Minute Revision

Original drill: A park committee says visitor satisfaction improved because complaints fell from 30 to 20. Before accepting the claim, ask how many visitors attended, whether complaint channels changed and whether the same measure was used.

A larger attendance with unchanged reporting would support one interpretation; a closed complaint desk would support another. None should be assumed without evidence. Formulate one strengthener and one weakener, then explain why each affects the inference rather than merely mentioning parks.
