  1. Question 1

    Q1. A drug trial shows 90% success in 100 patients. A conclusion: 'The drug is 90% effective.' What flaw exists?

    • A) Selection bias.
    • B) Overgeneralization.
    • C) Placebo effect.
    • D) Small sample size.

    Answer: Overgeneralization.

    Explanation: Generalizing from 100 patients is flawed. Overgeneralization is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
