Kelsey and Andreas are participating in the same two psychology experiments. The first task is to listen to a list of numbers and repeat them back in the same order. The second task is to determine from memory how many prime numbers are on the list. Kelsey has an IQ of 123 and Andreas has an IQ of 111. There ought to be a ____________ difference between Kelsey and Andreas's performance on the repetition task and a ____________ difference between Kelsey and Andreas's performance on the counting primes task.
A) small; small
B) great; great
C) great; small
D) small; great

There is no evidence to suggest that IQ is strongly associated with the ability to remember and repeat numbers in order or with the ability to count primes from a list. Therefore, we would expect the differences in performance between Kelsey and Andreas to be relatively small for both tasks. However, it is possible that Kelsey's higher IQ may give her a slight advantage on the prime-counting task, which requires more complex cognitive processing. Thus, we would expect a small difference on the repetition task and a somewhat larger difference on the prime-counting task.
