Question

Quizplus · Accepted Answer

The statement specifically states "EXCEPT" so we need to choose an option that does NOT reflect the reason for the increase in IQ. Genetics is not something that can change in the span of 30 years and therefore cannot be a reason for the increase in IQ in the 14 nations. The other options - improved education, improved nutrition, and living in a technologically complex society - can all contribute to an increase in IQ.
