Question

many neuroscientists:
○ believe that there may be a genetic component that influences intelligence.
○ are looking for a common factor in general intelligence.
○ still search but have not found the genetic foundations of intellectual capacity.
○ do not believe in the concept of intelligence.

Explanation:

Neuroscientists study the brain and nervous system. Intelligence is a complex trait. While there is evidence suggesting a genetic component (twin studies, family studies show some heritability), the exact genetic foundations are still being explored. They haven't fully mapped out the genetic basis of intellectual capacity yet.

Answer:

still search but have not found the genetic foundations of intellectual capacity.
