economists reason that the optimal decision is to continue any activity as long as the
marginal benefit is at least as large as the marginal cost.
marginal benefit is zero.
marginal cost is zero.
marginal benefit is less than the marginal cost.

Explanation:

In economics, the term "marginal" refers to "additional" or "extra". For example, marginal cost is the additional cost of producing one more unit. Regarding the optimal decision rule, economists use the principle that as long as the marginal benefit (the additional benefit from an activity) is at least as large as the marginal cost (the additional cost of the activity), it is rational to continue the activity. If marginal benefit is zero, there is no additional gain from continuing. If marginal cost is zero, it might seem good but the benefit - cost comparison is key. If marginal benefit is less than marginal cost, continuing would lead to a net loss.

Answer:

Question 1: marginal
Question 2: marginal benefit is at least as large as the marginal cost.
