1. I don't agree with this statement. Sometimes panic can determine life or death. But so can too much panic.
2. I don't agree with this statement. 300 people, and counting, have died while trying to reach the top. It's cold and dangerous.
3. I agree with this statement. Deserts are very hot. It's hard to find shelter, food, and water as well.
