people sneeze onto them

the food is allowed to cool to room temperature
of the long - term exposure to air

1. choose the best answer.

consider your digestive system and order foods that make you feel
full
happy
good
bad

Explanation:

For question 7:

• When food is allowed to cool to room temperature (the danger zone for bacteria growth is \(40^{\circ}F - 140^{\circ}F\) or \(4.4^{\circ}C - 60^{\circ}C\)), bacteria can multiply rapidly.
• People sneezing onto them is a possible but less common and less systematic risk compared to temperature - related issues.
• The ingredients themselves are usually safe when properly prepared, and long - term exposure to air is not the main reason (temperature control is more critical).

For question 8:

• Considering the digestive system, we should choose foods that make us feel good. Feeling full can sometimes be uncomfortable if over - eating.
• Feeling happy is more of an emotional response not directly related to the digestive system's well - being in a physiological sense.
• Feeling bad is obviously not the goal.

Answer:

1. the food is allowed to cool to room temperature
2. good
