What was a negative impact of "bonanza" farms?

a. output declined
b. farms got smaller
c. farms became disorganized
d. oversupply led to lower prices

i got D according to my book

heres what my book says: The farms' massive output caused problems, however. When the supply of a certain product rose faster than the demand, the market became glutted and prices fell.

OK. You're right, according to your book.

However my sources pointed out that because of the huge labor and machinery costs, the bonanza farms went broke when there was a drought or the price of wheat fell.

The negative impact of "bonanza" farms was that oversupply led to lower prices (option d). According to your book, the massive output of these farms caused problems as it led to an excess supply of certain products, causing the market to become saturated and prices to fall.

You are correct, the negative impact of "bonanza" farms was that oversupply led to lower prices (option d).

To arrive at this answer, you can analyze the information provided in your book. "Bonanza" farms were known for their massive output, which caused problems when the supply of a certain product increased more rapidly than the demand. This created an oversupply, which in turn led to a market glut and falling prices.

By understanding the concept of supply and demand, you can deduce that when there is an excess supply of a product and the demand does not keep up, the prices will naturally decrease. This negative impact on the market is precisely what option d, oversupply leading to lower prices, accurately describes.
