Answer:
being able to see complex relationships and solve problems
Explanation:
There are two classifications of intelligence: fluid and crystallized
Crystallized Intelligence refers to all knowledge acquired throughout school life and general knowledge stored by semantic memory. Unlike fluid intelligence, it reaches its apex in adulthood and remains in old age. It involves neocortical areas, temporal cortex and hippocampus.
On the other hand, Fluid Intelligence means the ability to solve problems, sustain attention, process information, infer and understand relationships between concepts, speed of thinking and mental flexibility. It presents its apex in adults and decline in old age, attributed to the atrophy of subcortical regions, white matter and prefrontal cortical areas and cingulate gyrus.
