Evidence Match
Choose evidence that directly addresses a particular claim.

How to play
Look for the same population, outcome and comparison as the claim. A related anecdote does not automatically test a general claim.
Use the feedback
Attempt an answer before looking at a hint or explanation. If it differs from the expected answer, compare the reasoning one step at a time. For a number problem, substitute your result back into the question. For a passage, point to the words that support your interpretation.
About this activity
This activity contains five original short questions with explanations. Repeating the set provides another chance to inspect the reasoning; it does not create an independent new test. There is no timer or competitive ranking. Correct-answer counts describe this task only.
Some puzzles can have more than one valid solution; grid checks accept any solution that meets the displayed constraints. Hints follow a known example solution. Familiarity, hints and previous attempts affect performance.
