readingWhich study would best support Park's malleability claim?
A
IQ tests have been used for a century
B
Children adopted into enriched environments showed 20-point IQ increases over 5 years; peers remaining in impoverished conditions showed no change
C
Some people score higher than others
D
Geneticists study intelligence
Correct Answer: B
Choice B is the best answer. Same starting point, different environments, different outcomes proves environmental influence.
💡 Strategy: Malleability claims need before/after data with environmental change.
