Some medicines are expensive. All expensive things are not affordable for everyone. Which conclusion follows?

  • A. Some medicines are not affordable for everyone
  • B. All medicines are unaffordable
  • C. No medicine is affordable
  • D. All expensive things are medicines

Explanation

The first statement covers only part of the class of medicines, so any valid conclusion must also be limited to some. Extending it to all medicines goes beyond what the premises support. The last option reverses the relationship, which is never valid.
