Extract the answer to the question from the following context. Question: What is the lowest grade level for the Gates Foundation reform? Context: The K-12 and higher education reform programs of the Gates Foundation have been criticized by some education professionals, parents, and researchers because they have driven the conversation on education reform to such an extent that they may marginalize researchers who do not support Gates' predetermined policy preferences. Several Gates-backed policies such as small schools, charter schools, and increasing class sizes have been expensive and disruptive, but some studies indicate they have not improved educational outcomes and may have caused harm. Peer reviewed scientific studies at Stanford find that Charter Schools do not systematically improve student performance

[Q]: Extract the answer to the question from the following context. Question: What field of study did naturalists believe they were a part of? Context: In Britain, William Paley's Natural Theology saw adaptation as evidence of beneficial "design" by the Creator acting through natural laws. All naturalists in the two English universities (Oxford and Cambridge) were Church of England clergymen, and science became a search for these laws. Geologists adapted catastrophism to show repeated worldwide annihilation and creation of new fixed species adapted to a changed environment, initially identifying the most recent catastrophe as the biblical flood. Some anatomists such as Robert Grant were influenced by Lamarck and Geoffroy, but most naturalists regarded their ideas of transmutation as a threat to divinely appointed social order.

input: Please answer the following: Extract the answer to the question from the following context. Question: How did the ocean ridges become denser? Context: To the north of Africa the Tethys Sea continued to narrow. Broad shallow seas advanced across central North America (the Western Interior Seaway) and Europe, then receded late in the period, leaving thick marine deposits sandwiched between coal beds. At the peak of the Cretaceous transgression, one-third of Earth's present land area was submerged. The Cretaceous is justly famous for its chalk; indeed, more chalk formed in the Cretaceous than in any other period in the Phanerozoic. Mid-ocean ridge activityor rather, the circulation of seawater through the enlarged ridgesenriched the oceans in calcium; this made the oceans more saturated, as well as increased the bioavailability of the element for calcareous nanoplankton. These widespread carbonates and other sedimentary deposits make the Cretaceous rock record especially fine. Famous formations from North America include the rich marine fossils of Kansas's Smoky Hill Chalk Member and the terrestrial fauna of the late Cretaceous Hell Creek Formation. Other important Cretaceous exposures occur in Europe and China. In the area that is now India, massive lava beds called the Deccan Traps were laid down in the very late Cretaceous and early Paleocene.

Extract the answer to the question from the following context. Question: what is the last nation mentioned? Context: After a lengthy period of formal racial segregation in the former Confederacy following the Reconstruction Era, and bans on interracial marriage in various parts of the country, more people are openly forming interracial unions. In addition, social conditions have changed and many multiracial people do not believe it is socially advantageous to try to "pass" as white. Diverse immigration has brought more mixed-race people into the United States, such as the large population of Hispanics identifying as mestizos. Since the 1980s, the United States has had a growing multiracial identity movement (cf. Loving Day). Because more Americans have insisted on being allowed to acknowledge their mixed racial origins, the 2000 census for the first time allowed residents to check more than one ethno-racial identity and thereby identify as multiracial. In 2008 Barack Obama was elected as the first multiracial President of the United States; he acknowledges both sides of his family and identifies as African American.
