Shawn is good at perceiving relationships and forming concepts.When confronted with a new problem,he can usually solve it.According to Cattell and Horn,Shawn has high __________ intelligence.

A) fluid
B) crystallized
C) practical
D) integrative

Fluid intelligence is the ability to solve new problems and think abstractly, which aligns with Shawn's ability to solve new problems. This is in contrast to crystallized intelligence, which is more focused on accumulated knowledge and skills. Practical intelligence is related to the ability to adapt to everyday situations, and integrative intelligence involves the ability to combine information from different sources to solve problems, but neither of these are as closely related to Shawn's described abilities as fluid intelligence.
