by helping to prevent food allergies by encouraging people to eat healthy foods by helping to keep people from becoming ill by curing diseases caused by lack of vitamins
I gave my students this multiple choice question: Louis Pasteur created a process that reduced the amount of bacteria in milk. How does this process most likely benefit people?

Only one answer is correct among these 4 choices:
- by helping to prevent food allergies
- by encouraging people to eat healthy foods
- by helping to keep people from becoming ill
- by curing diseases caused by lack of vitamins

Could you tell me which one is correct?
