How did braceros the war effort? they produce new varieties of vegetables. they produce more automobiles. they introduce irrigation for agriculture. they meet labor shortages for industry.

D) They helped meet labor shortages for industry.

The braceros program was an agreement between Mexico and the U.S to recruit more than 300,000 Mexicans to work low-paying agricultural jobs in the United States.

Although they did help run the railroads for the transportation of agricultural products, they did not produce more automobiles, therefore B is not the answer. Moreover, people were not hired to produce new varieties of vegetables nor was irrigation introduced by them, ruling out option A and C. The answer is D. Mexicans were brought to the U.S to help meet labor shortages for the agricultural industry, as there were not enough people working in it at the time.
