Table 1.3 shows the hypothetical trade-off between different combinations of brushes and combs that might be produced in a year with the limited capacity for Country X, ceteris paribus.Table 1.3Production Possibilities for Brushes and CombsCombinationNumber of combsOpportunity Cost(Foregone brushes)Number of brushesOpportunity Cost (Foregone combs)J4 0NAK3 10 L2 17 M1 21 N0NA23 On the basis of Table 1.3, in the production range of 1 to 2 combs the opportunity cost of producing 1 more comb in terms of brushes is

In which of the following situations would the minimum efficient scale of operation provide little or no guidance regarding how many firms should serve the market to minimize production costs?

A) When the LRAC curve slopes downward over the relevant range of output. B) When the LRAC curve hits its minimum point at a relatively low level of output and then increases and the demand for output is quite large. C) When the LRAC curve hits its minimum point at a relatively low level of output but then remains constant as the scale of operation is increased and the demand for output is quite large. D) When the LRAC curve initially increases and then decreases beyond some point.

a. supply depends on many other variables. b. price is a major determinant of quantity. c. it is a fixed amount. d. quantity cannot be determined in advance. e. All of the above are correct.
