by increasing the types of food available in stores by decreasing the amount of food sold in stores by increasing the time it takes to shop in stores by decreasing the number of stores
I gave my students this multiple choice question: A grocery company found a way to keep fresh foods from spoiling when transporting them long distances. How might this new technology help people in Hawaii?

Only one answer is correct among these 4 choices:
- by increasing the types of food available in stores
- by decreasing the amount of food sold in stores
- by increasing the time it takes to shop in stores
- by decreasing the number of stores

Could you tell me which one is correct?
