Answer:
The correct answer is A. The Bracero Treaty was an agreement to allow Mexican workers into the United States for one year.
Step-by-step explanation:
The Bracero Program was a series of laws and diplomatic agreements, initiated by an exchange in August of 1942 of diplomatic notes between the United States and Mexico, for the import of hired workers temporarily from Mexico to the United States.
The need for the program first arose during World War II, when there was demand for unskilled workers, and began with the US government promising a few hundred skilled Mexican farm workers to harvest sugar beet near Stockton, California. The program spread rapidly throughout the United States and provided workers in the agricultural labor market. As a result, but not directly related, negotiations were subsequently conducted that first traded unskilled unskilled railroad workers on US railways, but later extended to other unskilled and skilled labor. By 1945, the agricultural program had a limit of more than 50,000 workers, and the railway program had a limit of 75,000.
The railroad program was terminated rapidly with the end of World War II in 1945, but the agricultural program remained until 1964, when the governments of the United States and Mexico closed it due to harsh criticism and reports of human rights violations.
