If we add successive laborers to work a given amount of land on a wheat farm, eventually:. a. the increases in wheat harvested will get larger and larger.
b. average total cost will fall to zero.
c. the increases in wheat harvested will rise at a constant rate.
d. the increases in wheat harvested will get smaller and smaller.

d. the increases in wheat harvested will get smaller and smaller.

Explanation:

A marginal rate of technical substitution (MRTS) can be defined as an economic principle which is typically used to represent the rate at which a factor such as capital must decrease so that the same level or quantity of production is maintained when another factor such as labor is changed (increased).

An isoquant is the slope of a marginal rate of technical substitution (MRTS) which connects the two input factors provided that the level of output or production is the same.

Also, the diminishing marginal rate of technical substitution refers to the decline (fall) in marginal rate of technical substitution (MRTS) along an isoquant that produces the same quantity (level) of output.

When an isoquant has a diminishing marginal rate of technical substitution, the corresponding isoquants are convex to the origin. Thus, the marginal rate of technical substitution (MRTS) would continue to diminish as more of a factor such as capital is used.

If we add successive laborers to work a given amount of land on a wheat farm, eventually the increases in wheat harvested will get smaller and smaller.

d. the increases in wheat harvested will get smaller and smaller.
