A.   B and C
B.   A
C.   A and B
D.   B
Question #6
If the total product line slopes downwards:
A.   Marginal product is equal.
B.   Marginal product is positive.
C.   Marginal product is negative.
D.   Average product is increasing.
Question #7
During periods of increasing marginal productivity:
A.   Average product is increasing.
B.   Average product is constant, which leads to an increase in average product.
C.   Average product is decreasing.
D.   Marginal product is decreasing.
Question #8
Average total cost is equal to:
A.   Total cost divided by marginal cost.
B.   Total cost divided by total output.
C.   Fixed cost divided by number of workers.
D.   Fixed cost divided by total output.
E.   Total variable cost divided by total fixed cost.
Question #9
Total Cost is comprised of:
A.   Variable costs.
B.   Marginal costs plus variable costs.
C.   Fixed costs and variable costs.
D.   Fixed costs, but variable costs are excluded.
Question #10
Average variable cost:
A.   Is total output divided by variable costs.
B.   Is total fixed costs divided by total output.
C.   Is output plus variable costs.

Question #11
All else being equal, when marginal productivity falls:
A.   Average costs decline rapidly.
B.   Average costs must rise.
C.   Marginal costs must rise.
D.   Marginal costs must fall.
E.   Average costs must fall.
Question #12
The change or increase in cost associated with a one unit increase in output is called:
A.   Variable cost.
B.   Total cost.
C.   Declining relative costs.
D.   Average cost.
E.   Marginal cost.
Question #13
Declining marginal productivity is associated with increasing marginal costs:
A.   Because per-unit labor costs fall due to decreases in productivity.
B.   Due to increases in the size of a factory.
C.   Because economies of scale are being utilized.
D.   Because per-unit labor costs rise due to decreases in productivity.
Question #14
The distance between the Total cost (TC) curve and the variable cost (VC) curve is:
A.   Variable costs.
B.   Average fixed costs.
C.   Average total costs.
D.   Fixed costs.
Question #15
Average fixed costs (AFC) decline as production is increased:
A.   Due to the fact that fixed costs are being spread over an increasing number of units produced.
B.   Because total costs are declining.
C.   Due to the fact that production is becoming increasingly efficient.
D.   Due to the fact that variable costs are being spread over an increasing number of units produced.
Question #16
