Sleep researcher Dr. Thomas Chen argues that napping improves afternoon productivity more than caffeine does. He suggests naps restore alertness without the side effects of stimulants.
Which experimental result would best support Chen's comparative claim?
Many cultures have traditions of afternoon rest
Workers who took 20-minute naps made 30% fewer errors in afternoon tasks than those who consumed caffeine, and unlike caffeine users, nappers showed no decline in evening sleep quality
Caffeine is the world's most consumed stimulant
Some employers now provide nap rooms
Correct Answer: B
Choice B is the best answer. Direct comparison: naps beat caffeine on errors AND avoid side effects (sleep disruption).
- Context clues: Chen claims naps are better and have fewer side effects.
- Evidence evaluation: 30% fewer errors proves superior productivity; preserved sleep quality proves no side effects.
- Verify: Both the comparison and the side-effect claim are tested.
💡 Strategy: "Better with fewer side effects" claims need data on both effectiveness and side effects.
