b. access to expensive chemical fertilizers and pesticides
c. controlled population growth
d. the prohibition of hybridized crops
please select the best answer from the choices provided.
a
b
c
d

Explanation:

• Option A: Expansive infrastructure (like irrigation systems, transportation networks) and mechanized equipment (tractors, harvesters) boost agricultural productivity.
• Option B: Chemical fertilizers and pesticides, though expensive, can increase crop yields by providing nutrients and protecting from pests.
• Option C: Controlled population growth means less pressure on agricultural resources (less demand for food relative to available land and resources in some cases).
• Option D: Hybridized crops (which have desirable traits like higher yield, disease resistance) are widely used and promoted in US agriculture. Prohibiting them would be a hindrance, not a contributor to success.

Answer:

D. the prohibition of hybridized crops
