In my home, we have our own way to deal with tornadoes. If there is ever a tornado warning or watch, we head down to our basement and huddle up against a corner. We also have emergency kits that include food, water, flashlights, and other essentials that might be needed. By doing this, my family and I are being safe and prepared for any disaster that strikes.
Technically any of these. Are there any other details or specifics. I'd assume participating in sports because a diet only helps stress levels in the long term, watching television can relax a person but the other factors such as lack of social activity can contribute to a person's overall mental state and therefore increase stress levels, and studying can actually be relieving for some people depending on the mental state and needs of them but can obviously be a stresser. The only downfall to participating in sports is getting to excited or emotional during a game for example. But overall, C is the best choice.
