Answer
Farmers in the late 1800s wanted inflation because they hoped the rise in prices would increase their income.
Step-by-step explanation
Inflation is the rise in the general level of prices in the economy of a country. Farmers believed that if there is inflation they will be able to sell their products at good prices and make reasonable prices.
At this point they also needed to borrow large amounts of money (loans)as their capital investment in their lands.The inflation lowered the value of money and this made it easier for them to pay off the money they borrowed(loans).
