Final answer:
If you pass the person in second place in a race, you would then be in second place, as you have only overtaken the runner-up, not the leader.
Step-by-step explanation:
The riddle you have presented is a classic brain teaser used to challenge one's logical thinking. Upon passing the person in second place in a race, you would take their place, thus you would be in second place now. It's a common misconception to think you would be in first place, but you have only overtaken the runner-up, not the person in first place.
