According to your textbook, what is the most likely explanation for why first-born children tend to have higher IQ's?

A) prenatal exposure to flu
B) they are the oldest sibling and tutor younger siblings
C) temperature during infancy
D) exposure to sunlight during infancy


Answer: B
Rationale: Children born during the first part of the calendar year have higher verbal and mathematical aptitude, according to a number of sources. It appears that this is because children who are the oldest in their class get the most out of school, perhaps because they are, on average, slightly more mature and prepared to learn.
