Answer:
Luke meets the requirements for being assigned a diagnosis of intellectual disability.
Explanation:
An intellectual disability refers to certain social as well as intellectual limitations an individual has. The main limitations include having social skills, communication with others and general comprehension. It also means an inability or general difficulty to adapt.
In this case, Luke's intelligence score at 17 was below 98% of all the test takers, acknowledging a certain intellectual inability. Now, at 23 he still requires adult supervision since he has trouble adapting and living an independent life.
Intellectual disability is the diagnosis which best fits Luke's development.
