A grading program runs: if score >= 90 give A; elif score >= 80 give B; elif score >= 70 give C; else give F. For a score of 85, order what the program does.

1. Test score >= 90: false, so skip the A branch
2. Test score >= 80: true
3. Run the B branch
4. Skip every remaining branch, including the else

Conditions are checked top to bottom; the first true one (score >= 80) runs and every later branch, else included, is skipped. This is why order matters in an elif chain, putting a looser condition first would catch cases meant for a later branch.
