Final answer:
For a three-hour car trip during a blizzard, protein or granola bars are a good choice. One hour before a track meet, a banana and nuts provide sustained energy. For building muscle mass and healing injuries, Greek yogurt or lean chicken breast are good choices.
Step-by-step explanation:
In the first situation, when packing survival food for a three-hour car trip during a severe blizzard, it is important to choose foods that are non-perishable and can provide a quick source of energy.
One good choice would be protein bars or granola bars. These snacks are compact, easy to carry, and provide a good balance of carbohydrates, protein, and fats.
In the second situation, when eating one hour before a track meet, it is important to choose foods that can provide sustained energy.
A good choice would be a banana and a handful of nuts. The banana is a rich source of carbohydrates for immediate energy, while the nuts provide healthy fats and protein for sustained energy.
In the third situation, when trying to build muscle mass and/or heal injuries, it is important to choose foods that are high in protein.
A good choice would be Greek yogurt or lean chicken breast. These foods provide a good amount of protein which is essential for muscle growth and repair.
