Which of the following can be seen as an indication that intelligence has a strong genetic basis?

a. though reared in a book-free environment, jason loves reading and is an excellent student.
b. brianna's iq scores are nearly the same as those of her identical twin suzanna.
c. alec excels at academics, while his fraternal twin zack is better at sports.
d. camilla enjoys reading the same sorts of books as her mother.

The answer is  B) Brianna's IQ scores are nearly the same as those of her identical twin Suzanna.

Explanation:

The question deals with intelligence and its genetic basis, so the answer must refer to both of those key words.

- The first option just describes Jason's intelligence inderectly by putting him as an excellent student, but there is no connection with his genetics.

- The third option describes some differences between siblings (so there is a genetic connection) but there is nothing directly related to a way of measuring intelligence.

- The last option shows a genetic link because of the daughter-mother relationship, but once again, reading books is not an intelligence measure.

- In contrast, the second option, mentions IQ scores, which is a way of measuring intelligence and, at the same time, it shows a genetic link between Brianna and Suzanna (identical twins).
