Answer: b. increasingly improved childhood health and nutrition

Explanation: The Flynn Effect describes the tendency of intelligence quotient scores to vary over time, most especially the apparent increase in intelligence in the general population supported by a steady increase in intelligence quotient scores. This increase in IQ scores would be attributed according to the Flynn theory to increasingly improved childhood health due to proper nutrition and education as a result of people reading more, and new technology forcing people to think more abstractly. All of this leading to an increase in the IQ score.
