Ashley, a psychology major, remarks that she has become interested in the study of intelligence. thus, ashley is interested in: a. how behavior changes as a result of experience. b. the capacity to solve problems, adapt to the environment, and learn from experience. c. the ability to generate valuable and original solutions to problems. d. obtaining, using, and converting knowledge.

I believe the answer is: B.  the capacity to solve problems, adapt to the environment, and learn from experience.
The level of intelligence would determine the processing speed inside our brain which would influence our capacity to solve the problems that exist in the environment.
High intelligence wouldn't guaranteed a success or higher understanding on specific subject since effor also play a huge role in this. But it would most likely influence how easy it is for the individual to learn new things.
