Godinez: In the past, land was sometimes measured by the amount of time required to plow it. Thus, two plots of equal physical dimensions were considered unequal if one was more difficult to plow than the other. However, knowing how long an area takes to plow reveals little about how many apartment complexes it can hold. Ttherefore, it became necessary to adopt new measures of land, such as acreage, when land uses diversified. Which one of the following most accurately expresses the main conclusion drawn in Godinez's argument? ['Some plots of land that would have been considered unequal by plowing-time measurements are of equal physical dimensions.', 'The advent of diversified land uses made new measures of land necessary.', 'Modem measures of land were adopted when people realized that plowing time was an inadequate measure for some land uses.', 'It is now easier to measure a piece of land in terms of acres than in terms of plowing time.']
