Answer :
I believe the answer is: abstract; concrete
Abstract thought refers is characterized by thinking about a situation or a principle that hasn't happen (such as what would happen if sun blow up, what would happen if cars can fly, etc)
Concrete thought on the other hand is characterized by thinking about something or reasoning that already exist in our physical world.
