Why is 'I may miss ten questions' an unsafe way to think about the Category B pass mark?

1. Because items carry different point values that total 97, and the pass is 87 points rather than a fixed miss count
2. Because the terminal only awards a pass or fail and never shows points
3. Because a candidate must answer every item correctly to reach 87 points
4. Because every question is worth exactly one point, so ten misses always fail the paper
