Two groups of students made plans to their school prepare for tornadoes. the first group suggested having tornado drills to students identify basements and other safe areas during tornadoes. the second group suggested making the school building tornado proof by using special materials for doors and windows. why is having tornado drills to students identify safe areas a better method to prepare for tornadoes than using special materials for doors and windows it is easier to identify safe areas than put new doors and windows. it is less expensive to find safe areas than to change all the doors and windows. safe areas provide better protection from tornadoes than special doors and windows. safe areas are more environmentally friendly than materials used for doors and windows.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
