D. Scientists make food that wouldn't fall apart and that has very little packaging.
Explanation:
Option D is the correct answer. It is the best choice I will enter in the "What I Learned" column.
From the text, I learn that scientist actually make food that wouldn't fall apart and float away. We see that such can be achieved in the food made and the packaging of the food. Less wrapping of food which leads to less packaging actually reduces the chance of causing harm to the body.
So, making food that wouldn't fall apart and that also have very little packaging by scientists is what I learned.
