It is better to evaluate economic decisions at the marginal, where the decision has to be made as long as its marginal benefit exceeds its marginal cost, if not equal to its marginal cost. A. True
B. False

True

Explanation:

Output is always maximised where Marginal Benefit is above Marginal Cost. Ideally speaking, Marginal Benefits should be equal to Marginal Costs but Marginal Benefits being greater than cost is still a good thing because it means that there is still room for expansion until such a point as the MB = MC.

However, if it starts costing more per unit to gain a benefit per unit MB < MC, the decision makers can know to limit the activity because this will cause losses. This is why it is better to make decisions at a Marginal level so that one may know when output is maximised as well as when to rein in production.
