Feral children are in their own homes.
a. institutionalized
c. socialized
b. held captive
d. isolated ?

Feral is a word usually use to describe something that is wild.  An out door cat who has not contact with humans.
So I think the answer is isolated in their own homes, but if you think about it they could be held captive as well and isolated.

People need to distract themselves with actitives. they can also find a natural high. an example would be eating alot of meat. that meat can release dopamine to the brain which gives one a natural high feeling.
