Answer:
This would mean that James is A) high in crystallized intelligence and low in fluid intelligence.
Explanation:
Crystallized intelligence is a type of intelligence that comes from knowledge obtained via past experiences and learning. When James says he "know(s) the ropes" regarding his job, he means he has enough experience acquired from the 30 years doing it. That sort of experience clearly must make certain aspects of his job easier. He must know how to deal with certain situations that have repeatedly occurred in the past, for instance. On the other hand, fluid intelligence refers to someone's ability to solve problems in situations that are new, unexpected, or unusual. That is what James lacks. He says he is "slower on the uptake", meaning he has a hard time figuring out new situations.
