Which learning study would best support Wong's spaced practice claim?

A

Students often cram

B

Students who studied 30 minutes daily for 6 days retained 50% more material after 30 days than those who studied 3 hours the night before, despite equal total study time

C

Memory is complex

D

Some students study more

Correct Answer: B

Choice B is the best answer. Same total time + different distribution + 50% better retention proves spacing effect.

💡 Strategy: Learning method claims need controlled comparisons with equal total effort.
