Answer #1

Q1 Answer is B. Returns.
When we add more variable input then marginal output or returns of inputs decreases which is called diminishing marginal returns.
Q2 Answer is B. Marginal
Change in cost when one more unit is produced is called marginal cost.
Q3 Answer is D. Some: All
In long run all inputs are variable and in short run some inputs are variable and some are fixed.
Q4 Answer is D.
Entry of new firms will increase the supply and decrease the price for all firms and profits of all firms will decrease to normal in long run.
