What was the goal of the farm labor movement?

put California growers out of business

prohibit farm workers from joining unions

press for change through radical protest

achieve better working conditions for farm workers

I believe the answer is: achieve better working conditions for farm workers

In the past, most of farm works are given to immigrants from another country since they are willing to accept very little payment.

That's being said, farmers still made to live in farming territory and experience harsh working condition such as long working hours, unsanitary water, no weather protection, etc

The goal of the farm labor movement was to achieve better working conditions for farm workers. One of the famous farm labor movements in the United States is the United Farm Workers of America or also known as United Farm Workers.

The answer would be the fourth choice.
