Question $14(1$ point$)$

In the standard model of labor supply and demand, what happens to MPL as more workers are hired?

It decreases, because it is hard to find additional, good workers.

It decreases, because the capital that labor uses is limited $($in the short run$).$ It increases, because more workers increase productivity $($i$.$e$.$ they can take breaks$).$

It increases, as supply usually does.
