Strengthening Arguments guide

Strengthening questions ask which new fact would most support the argument. The best strengthener closes the specific gap between the premises and the conclusion — strengthen does not mean prove.

The method

  1. Pinpoint the gap the argument leaves between its premises and its conclusion.
  2. Choose the option that closes that particular gap.
  3. Remember strengthen ≠ prove — you want the biggest honest push, not certainty.
  4. Check the option supports this conclusion, not a nearby different one.

Common mistakes

Frequently asked questions

Does the strengthener have to prove the conclusion?

No. It only has to make the conclusion more likely by closing the argument's gap — the strongest available push, not a proof.
