IQ is positively correlated with working memory capacity, which is important for the first task of repeating a list of numbers in the correct order. Therefore, there should be a small difference between Kelsey and Andreas's performance on the repetition task. However, IQ is not as strongly correlated with the ability to identify prime numbers, so there may be a larger difference in performance between Kelsey and Andreas on this task. Thus, the answer is small for the repetition task (D) and large for the prime number counting task (C).
