At a recent um football game, a terrorist group flew a crop duster over the stadium and dusted the western side of the stands with anthrax spores. fortunately, the wind was blowing toward the west. once cases were discovered, the investigation began. a total of 100 people who sat on the eastern side developed disease and 1000 people who sat on the western side developed disease. of the 100,000 people in attendance, 50,000 were sitting on the western side of the stadium and were considered to have been exposed.

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.
