question 6
an increase in the unemployment rate may be represented as a movement from a point on the production possibilities frontier to a different point in the interior.

Explanation:

Step1: Recall opportunity - cost formula

Opportunity cost = $\frac{Quantity\ of\ forgone\ good}{Quantity\ of\ gained\ good}$
For George, when cultivating a garden, the forgone good is mowing lawns.

Step2: Identify relevant quantities

George can mow 10 lawns or cultivate 5 gardens in a day.
The opportunity cost of cultivating 1 garden for George is the number of lawns he gives up.
Opportunity cost of cultivating 1 garden = $\frac{Number\ of\ lawns\ mowed}{Number\ of\ gardens\ cultivated}$ = $\frac{10}{5}=2$ lawns mowed.

Answer:

Two lawns mowed
