Extract the answer to the question from the following context. Question: Higher levels of CO2 lead to two things, average temperatures being higher by about 10 degrees and? Context: The climate of the Cretaceous is less certain and more widely disputed. Higher levels of carbon dioxide in the atmosphere are thought to have caused the world temperature gradient from north to south to become almost flat: temperatures were about the same across the planet. Average temperatures were also higher than today by about 10C. In fact, by the middle Cretaceous, equatorial ocean waters (perhaps as warm as 20 C in the deep ocean) may have been too warm for sea life,[dubious discuss][citation needed] and land areas near the equator may have been deserts despite their proximity to water. The circulation of oxygen to the deep ocean may also have been disrupted.[dubious discuss] For this reason, large volumes of organic matter that was unable to decompose accumulated, eventually being deposited as "black shale".

Extract the answer to the question from the following context. Question: What kind of group of Muslims such as the Druze and Alawites were claimed as heretical? Context: Muslim sects regarded as heretical, such as the Druze, Ismailis, Alevis, and Alawites, ranked below Jews and Christians. In 1514, Sultan Selim I, nicknamed "the Grim" because of his cruelty, ordered the massacre of 40,000 Anatolian Alevis (Qizilbash), whom he considered heretics, reportedly proclaiming that "the killing of one Alevi had as much otherworldly reward as killing 70 Christians."[page needed] Selim was also responsible for an unprecedented and rapid expansion of the Ottoman Empire into the Middle East, especially through his conquest of the entire Mamluk Sultanate of Egypt, which included much of the region. With these conquests, Selim further solidified the Ottoman claim for being an Islamic caliphate, although Ottoman sultans had been claiming the title of caliph since the 14th century starting with Murad I (reigned 1362 to 1389). The caliphate would remain held by Ottoman sultans for the rest of the office's duration, which ended with its abolition on 3 March 1924 by the Grand National Assembly of Turkey and the exile of the last caliph, Abdulmecid II, to France.

Extract the answer to the question from the following context. Question: What geographic features can be found here? Context: In eastern Pennsylvania the Great Appalachian Valley, or Great Valley, was accessible by reason of a broad gateway between the end of South Mountain and the Highlands, and many Germans and Moravians settled here between the Susquehanna and Delaware Rivers forming the Pennsylvania Dutch community, some of whom even now speak a unique American dialect of German known as the "Pennsylvania German language" or "Pennsylvania Dutch." These latecomers to the New World were forced to the frontier to find cheap land. With their followers of both German, English and Scots-Irish origin, they worked their way southward and soon occupied all of the Shenandoah Valley, ceded by the Iroquois, and the upper reaches of the Great Valley tributaries of the Tennessee River, ceded by the Cherokee.
