Answer to Question 1

The law of diminishing returns states that as a firm uses more of a variable factor, with a given quantity of fixed factors, the marginal product of the variable factor eventually decreases. This proposition is called a law because there is no case where adding more labor, capital, materials, fuel or any other variable factor will cause output to increase indefinitely. Eventually, adding any variable factor to some fixed factor will lead to smaller and smaller additions to output. If the law of diminishing returns did not always hold true, farmers could grow the entire world's supply of food on one acre of land, by just adding more water and more fertilizer (variable factors) to the acre (the fixed factor).
