Help please

Answer

a. Definitely True

b. Possibly true

c. Definitely false

d. Possible true

Explanation:

The amount of time from 7:00pm to 8:00pm is 1 hour. The text says he finished after 8pm. So since "a" says that it took him more than 1 hour it is definitely true. "b" is possibly true but we don't have enough in for make it definite because we don't know the exact stopping time. But, since we know it took more than 1 hour ad 2 > 1 that could be true. "c" is definitely wrong because he finished at least 1 hour after he started so you can't go less than that. "d" could be true because even if it took him less than 2 hours he could of still taken more than 1 hour within the less than 2 constraint.
