A Group of People Is Discussing Whether the State Should

Multiple Choice

A group of people is discussing whether the State should invest more money into education. Stuart argues that since intelligence is a highly heritable trait, it is pointless to spend taxpayers' money on educational facilities. With respect to Stuart's comment, which of the following statements is the most ACCURATE?

A) Stuart is wrong. Intelligence is never heritable but it is mostly influenced by environmental factors, such as housing, nutrition, schooling, and social stability.
B) Stuart is right. Intelligence is mostly determined by genetic variation, with little contribution from the environment.
C) Stuart is wrong. Intelligence can be highly heritable in affluent social groups, where the environment is very good for everyone. But the contribution of genetic variation is lower in social groups with lower socio-economic status due to higher variation of environmental factors.
D) Stuart is right. Intelligence is fully determined by genetic variation, especially in social groups with low socio-economic status.
