D. Increased mechanization has increased food production, thereby increasing the need for labor

Explanation:

The agriculture in the United States has changed significantly during the 1900's. From being primitive in the manner in which the farming was done, the agricultural field became much more modernized. The new technologies had invented lot of mechanization specifically for this field, and that has helped a lot. The food production skyrocketed because the mechanization was making everything much more easy. The work on much larger areas was done much quicker, more efficient, and cheaper. That has resulted in much higher production of food, which in turn resulted in higher demand for labor force. The labor force in the agriculture though gradually has changed, as the Americans themselves started to avoid the farming, but the immigrants from Latin America welcomed the opportunity and gradually became the dominant labor force in this field.

A. Increased mechanization has reduced the need for labor.

Explanation:

Before 1900 more Americans  were engaged in farming and about 90 percent of the population are engage in farming. The farming was mainly for subsistence purpose to carter for the family. As the population increases more lands were used for farming .

During the 20th centuries industrialization and urbanization contributed to the progressive decrease in the number of individual engage in agriculture . This period the agriculture profession progressively became commercialized . Advances were made in the irrigation method. Gas geared tractor were engaged , commercial fertilizers rapidly increased in most farms . The transportation method improved also and this encourage commercialization farming in perishable goods.

The rural farmers and herders left their farms to seek job as the profession became more commercialize .

Generally, the increased mechanization reduces job as machine takes the place of humans labor.
