Researchers tested four study techniques on the same students. They recorded short-term recall (24 hr later) and long-term recall (1 month later), in % of facts retained: Technique I, 80% short / 30% long; Technique II, 65% short / 55% long; Technique III, 72% short / 35% long; Technique IV, 60% short / 58% long. The researchers concluded that techniques with the highest short-term recall are not necessarily the best for long-term retention. The data most uniquely supporting this counterintuitive claim is ______
Which choice most logically completes the text using the data above?
- Acheck_circle
the rank reversal: Technique I has highest short-term recall (80%) but the lowest long-term recall (30%); Technique IV has lowest short-term but highest long-term.
- B
the average recall across techniques.
- C
Technique IV's lowest short-term recall (60%).
- D
Technique I's high short-term recall.
Explanation
The claim is that short-term ranking misleads about long-term ranking. Choice B captures the rank reversal—the same data point that uniquely supports the counterintuitive conclusion.
