GRE Analytical Writing (Argument) evaluates your ability to assess evidence and causal reasoning. The original claim asserts causation (music → sales increase) but offers only a temporal correlation (after music, sales rose). The strongest revision introduces a comparison group and isolates the purported causal factor’s timing: weekend sales (with music) rose, weekday sales (without music) did not. This quasi-control improves internal validity by reducing alternative explanations shared across all days (e.g., seasonal trends, marketing). Option B is irrelevant sentiment—compliments don’t establish causality. Option C undermines the claim by suggesting a broader regional trend could explain the increase. Option D is too coarse; many factors could raise annual revenue. Good AWA practice is to seek evidence that (1) aligns changes with the intervention, (2) contrasts outcomes where the intervention is absent, and (3) rules out plausible confounds. While not a randomized experiment, the weekend-weekday contrast is a reasonable strengthening step consistent with GRE objectives: critique assumptions, identify needed evidence, and improve argument structure.
