during the green revolution, agricultural practices from more developed countries diffused to less developed countries in asia and africa. which of the following best explains the green revolutions highly variable level of success in increasing agricultural yields?
a the increased yield of the green revolution in sub - saharan africa decreased the incidence of famine, but the program was unsuccessful in india because of poor soil quality.
b small - scale farmers in asia often lacked the resources necessary to acquire the hybrid seeds and the chemical inputs to grow them, leaving large gaps in the success of the green revolution outside of urban cores.
c the green revolution was not successful in china because the strain of rice produced was prone to widespread crop failures, and china dropped out of the program.
d rice production surpassed all other crop production in sub - saharan africa, but corn production in mexico was less successful because of the negative impact on the environment.
e persistent famine has occurred in india since new technologies associated with the green revolution were implemented because only the wealthy could afford the increased cost of the improved strains of rice.

e  persistent famine has occurred in india since new technologies associated with the green revolution were implemented because only the wealthy could afford the increased cost of the improved strains of rice.

Accepted Answer

# Brief Explanations:
- Option A: The Green Revolution was successful in India (improved yields), so this is incorrect.
- Option B: Small - scale farmers in Asia often couldn't afford hybrid seeds and chemical inputs (like fertilizers, pesticides). This lack of resources meant that the Green Revolution's technologies (which relied on these inputs) couldn't be fully adopted, leading to variable success. This matches the idea of variable success due to resource access.
- Option C: The Green Revolution was successful in China (e.g., hybrid rice varieties improved yields), so this is incorrect.
- Option D: The Green Revolution in Mexico (corn) was successful, and sub - Saharan Africa's rice production isn't the main issue for variable Green Revolution success. This is incorrect.
- Option E: India saw increased agricultural yields from the Green Revolution, and famine was reduced (not persistent), so this is incorrect.

# Answer:
B. Small - scale farmers in Asia often lacked the resources necessary to acquire the hybrid seeds and the chemical inputs to grow them, leaving large gaps in the success of the Green Revolution outside of urban cores.
