Answer:
a. Fluid intelligence
Explanation:
Cattell-Horn's theory of fluid and crystallized intelligence suggests that intelligence is composed of a series of different skills that interact and work together to produce general individual intelligence.
<u>
Fluid intelligence</u> implies being able to think and reason abstractly and solve problems. This ability is considered independent of learning, experience and education. It is basically configured by primary skills such as induction, deduction, relationships and figurative classifications, breadth of associative memory and intellectual speed, among others. It reaches its maximum splendor in the early twenties and tends to decrease in parallel to the aging and deterioration of neurons. This ability can be measured from tests that measure the biological potential of the individual to learn or acquire knowledge.
