1. choose the best answer.

why is it best to consider your digestion?
you might not like the new foods and will leave hungry.
you do not want to eat too little.
certain foods might be unsafe.
you want food that makes you feel good.

Explanation:

For the first question, salad bars and buffets are unsafe because food exposed to air for long - bacteria reproduce. Refrigeration slows bacteria (so first option wrong). No info on cancer - causing toxins or organic quality.
For the second question, considering digestion is about food that makes you feel good. Not about liking food (hunger), eating too little, or food safety (unless digestion - related safety, but this is more about comfort).

Answer:

1. The food may be exposed to the air for a long time, letting bacteria reproduce.
2. You want food that makes you feel good.
