Question: Which of the cities in the Upper Peninsula of Michigan where a very large snowbelt exists has the largest population? Passage:A very large snowbelt in the United States exists on the Upper Peninsula of Michigan, near the cities of Houghton, Marquette, and Munising. These areas average of snow each season. For comparison, on the western shore, Duluth, Minnesota receives per season. Lake Superior and Lake Huron rarely freeze because of their size and depth; hence, lake-effect snow can fall continually in the Upper Peninsula and Canadian snowbelts during the winter months. Main areas of the Upper Peninsula snow belt include the Keweenaw Peninsula and Baraga, Marquette and Alger counties, where Lake Superior contributes to lake-effect snow, making them a prominent part of the Midwestern snow belt. Records of of snow or more have been set in many communities in this area. The Keweenaw Peninsula averages more snowfall than almost anywhere in the United States—more than anywhere east of the Mississippi River and the most of all non-mountainous regions of the continental United States. Because of the howling storms across Lake Superior, which cause dramatic amounts of precipitation, it has been said that the lake-effect snow makes the Keweenaw Peninsula the snowiest place east of the Rockies. Only one official weather station exists in this region. Located in Hancock, Michigan, this station averages well over per year. Farther north in the peninsula, lake-effect snow can occur with any wind direction. The road commission in Keweenaw County, Michigan collects unofficial data in a community called Delaware, and it strictly follows the guidelines set forth by the National Weather Service. This station averages over per season. Even farther north, a ski resort called Mount Bohemia receives an unofficial annual average of . Herman, Michigan, averages of snow every year. Lake-effect snow can cause blinding whiteouts in just minutes, and some storms can last days.

Question: What country was the first Islamic Missionary to reach the Sulu Archipelago from? Passage:Arab traders have been visiting Philippines for nearly 2000 years for trade purposes, and traded extensively with local Malayan chiefs, datos and Rajahs that had various Rajahnates in the region. Arab and Persian traders passed by the Philippines, on their way to Guangzhou, China. These early Arab traders followed the pre-Islamic religions of Arabian Christianity, Paganism and Sabeanism. After the advent of Islam, in 1380, Karim ul’ Makhdum, the first Islamic missionary to reach the Sulu Archipelago, brought Islam to what is now the Philippines, first arriving in Jolo. Subsequent visits of Arab Muslim missionaries strengthened the Islamic faith in the Philippines, concentrating in the south and reaching as far north as Manila. Starting with the conquest of Malaysia by the Portuguese and Indonesia by the Dutch, the Philippines began to receive a number of Malaysian-Arab refugees including several Malaysian princes and displaced court advisors. Soon, vast sultanates were established overlapping the existing indigenous Filipino barangay (village) governing system and Indianized royalty. The two largest were the Sultanate of Maguindanao, which loosely governed most of southern Mindanao and the Sultanate of Sulu, which included Basilan, Jolo, and parts of Borneo. Several other smaller but famous sultanates were also established such as the sultanate of Lanao in Mindanao, which was later conquered by the Spanish in the 16th century. The ties between the sultanates in Mindanao remained economically and culturally close to Indonesia, Brunei, and Malaysia until the end of the 19th century when the sultanates were weakened by the Spanish and later the American militaries.
