Answer: Farm Hands
Step-by-step explanation:
A Farm hand is someone who is employed to work on a farm to engage in work that will make the farm more profitable such as planting and harvesting crops, feeding animals, and other general farm duties.
Iowa produces the most corn in the United States and if there was a drought that causes the crop to fail, a lot of farms would lose profitability.
The first people who would lose their jobs would be the farm hands as farms would no longer be able to afford to pay them only retaining a few for the most integral of tasks.
