B.   A and B
C.   B
D.   B and C
Question #6
If the total product line slopes downwards:

B.   Marginal product is equal.
C.   Average product is increasing.
D.   Marginal product is negative.
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.   Marginal product is decreasing.
D.   Average product is decreasing.
Question #8
Average total cost is equal to:
A.   Total variable cost divided by total fixed cost.
B.   Fixed cost divided by number of workers.
C.   Total cost divided by marginal cost.
D.   Total cost divided by total output.
E.   Fixed cost divided by total output.
Question #9
Total Cost is comprised of:
A.   Variable costs.
B.   Fixed costs, but variable costs are excluded.
C.   Marginal costs plus variable costs.
D.   Fixed costs and variable costs.
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.   Marginal costs must rise.
B.   Average costs decline rapidly.
C.   Average costs must rise.
D.   Average costs must fall.
E.   Marginal 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.   Declining relative costs.
C.   Marginal cost.
D.   Total cost.
E.   Average cost.
Question #13
Declining marginal productivity is associated with increasing marginal costs:
A.   Due to increases in the size of a factory.
B.   Because per-unit labor costs rise due to decreases in productivity.
C.   Because per-unit labor costs fall due to decreases in productivity.
D.   Because economies of scale are being utilized.
Question #14
The distance between the Total cost (TC) curve and the variable cost (VC) curve is:
A.   Average total costs.
B.   Average fixed costs.
C.   Fixed costs.
D.   Variable 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.   Due to the fact that production is becoming increasingly efficient.
C.   Due to the fact that variable costs are being spread over an increasing number of units produced.
D.   Because total costs are declining.
Question #16
