6. The MC curve goes through the minimum point of which of the following curves?
4
7. The MC curve eventually rises as output increases in the short run because of A) the law of diminishing returns B) diseconomies of scale C) constant returns to scale D) economies of scale

11. What explains why the SR AVC curve eventually increases as output rises? A) diseconomies of scale B) the law of diminishing returns C) economies of scale D) constant returns to scale
12. A firm doubles its output in the long-run and at the same time the per-unit (average) cost of production remains unchanged. We can conclude that the firm is
