Read the paragraph. [1] By the end of the 1800s, there was a change in the nature of the immigrants coming to the United States. [2] Immigration from Northern Europe—England, Ireland, Germany, and Scandinavia—declined, while immigration from Italy, Russia, and Austria-Hungary grew. [3] In fact, between 1900 and 1910, more than three-fourths of all immigrants came from these three countries. [4] Unfortunately, these countries were far removed from England, the home of our founders, and the immigrants who came from them had a hard time adjusting to life in their new country. Which sentence in the paragraph does not include facts to support the main ideas of the paragraph?

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.
