QUESTION TEXT: Carpal tunnel syndrome, a nerve disorder that…
QUESTION TYPE: Paradox
PARADOX: You get more carpal tunnel if you can’t control your own work, even if you do the same amount of typing as workers who do have control.
ANALYSIS: The study made a very strict comparison. It compared workers who did similar amounts of typing. The only difference was how much control they had over their work.
Several wrong answers incorrectly compare workers who do different amounts of typing.
We need to find a reason that low control leads to more carpal tunnel. For example, maybe low control workers can’t decide when to take breaks from typing.
The right answer instead shows that low control weakens nerves. Carpal tunnel is a nerve disease.
- The study looked at workers who did similar amounts of typing.
- CORRECT. Carpal tunnel is a nerve disorder. This shows that not having control increases your risk of this and other nerve diseases.
- This doesn’t explain why workers with little control get even more carpal tunnel.
- The study compared only workers who typed a similar amount.
- This adds to the confusion. If workers with the most control do more repetitive actions, then why do they get less carpal tunnel.
