The response that best supports the argument that biotechnology has had a positive impact on both society and the United States' economy is:
d Shull's creation of hybrid corn seed allowed farmers to produce more corn consistently throughout the years. Overall, the number of bushels harvested each year trends higher, as shown in the graph, between 1918 and 2011. Increased corn production meant more income for the farmers, which allowed them to take better care of their families and farms. Hybrid seed performed, even during the Dust Bowl, when non-hybrid farmers struggled to produce corn.
This choice explicitly discusses the positive outcomes of Shull's hybrid corn seed, emphasizing increased production, economic benefits for farmers, and the resilience of hybrid corn during difficult growing conditions.
