Question

how did ethical beliefs play a part in the implementation of golden rice?
people supported golden rice because it helped cut down on the cost of multivitamins.
people supported golden rice because the rice was visually appealing.
people supported golden rice because it made farmers a lot of money
people supported golden rice because it helped solve food and nutrition problems.

Explanation:

Ethical beliefs often center around helping others and addressing societal problems. Golden rice was developed to address vitamin A deficiency (a nutrition problem) and food security issues. Cutting down multivitamin cost (if true) is more of an economic aspect. Visual appeal is a superficial reason. Making farmers a lot of money is more of an economic - agricultural aspect rather than an ethical one. Solving food and nutrition problems aligns with the ethical belief of helping those in need (e.g., preventing blindness and malnutrition in vulnerable populations).

Answer:

People supported golden rice because it helped solve food and nutrition problems.
