Answer:
Output in country A increases by less than in country B.
Step-by-step explanation:
Country A and country B are the same except country A currently has a lower level of capital. Assuming diminishing returns, if both countries increase their capital by 100 units and other factors that determine output are unchanged, then output in country A increases by less than in country B because of the lower capital and However, due to diminishing returns to scale,If output increases by less than that proportional change in all inputs, there are decreasing returns to scale
