easy · LSAT Logical Reasoning

A pharmaceutical company claims that its new drug is effective because, in a trial, 80 percent of patients reported feeling better. The trial included no control group receiving a placebo.

The trial is flawed because it fails to:

  1. Establish how much improvement would have occurred even without the drug's active effect.
  2. Verify that the patients enrolled were truly representative of the broader patient population.
  3. Take into account that the drug, besides helping, might also cause harmful side effects.
  4. Spell out the biological mechanism through which the drug is supposed to improve health.
  5. Confirm that the drug works equally well in every age group and demographic category.
