Final answer:
Fluid intelligence is the ability to solve complex problems, while crystallized intelligence is the ability to acquire and retrieve knowledge. They are both important in different ways.
Step-by-step explanation:
Fluid intelligence is the ability to see complex relationships and solve problems, while crystallized intelligence is characterized by acquired knowledge and the ability to retrieve it. Crystallized intelligence is demonstrated when you learn, remember, and recall information from your coursework. On the other hand, fluid intelligence helps you tackle complex, abstract challenges in your daily life. For example, navigating an unfamiliar route due to road construction requires fluid intelligence.
