Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: What are earthwork mounds made of? Passage:Indigenous peoples inhabited Missouri for thousands of years before European exploration and settlement. Archaeological excavations along the rivers have shown continuous habitation for more than 7,000 years. Beginning before 1000 CE, there arose the complex Mississippian culture, whose people created regional political centers at present-day St. Louis and across the Mississippi River at Cahokia, near present-day Collinsville, Illinois. Their large cities included thousands of individual residences, but they are known for their surviving massive earthwork mounds, built for religious, political and social reasons, in platform, ridgetop and conical shapes. Cahokia was the center of a regional trading network that reached from the Great Lakes to the Gulf of Mexico. The civilization declined by 1400 CE, and most descendants left the area long before the arrival of Europeans. St. Louis was at one time known as Mound City by the European Americans, because of the numerous surviving prehistoric mounds, since lost to urban development. The Mississippian culture left mounds throughout the middle Mississippi and Ohio river valleys, extending into the southeast as well as the upper river.

Question: How old was Norimasa kaeriyama when he directed The Glow of Life? Passage:Among intellectuals, critiques of Japanese cinema grew in the 1910s and eventually developed into a movement that transformed Japanese film. Film criticism began with early film magazines such as Katsudō shashinkai (begun in 1909) and a full-length book written by Yasunosuke Gonda in 1914, but many early film critics often focused on chastising the work of studios like Nikkatsu and Tenkatsu for being too theatrical (using, for instance, elements from kabuki and shinpa such as onnagata) and for not utilizing what were considered more cinematic techniques to tell stories, instead relying on benshi. In what was later named the Pure Film Movement, writers in magazines such as Kinema Record called for a broader use of such cinematic techniques. Some of these critics, such as Norimasa Kaeriyama, went on to put their ideas into practice by directing such films as The Glow of Life (1918), which was one of the first films to use actresses (in this case, Harumi Hanayagi). There were parallel efforts elsewhere in the film industry. In his 1917 film The Captain's Daughter, Masao Inoue started using techniques new to the silent film era, such as the close-up and cut back. The Pure Film Movement was central in the development of the gendaigeki and scriptwriting.

Question: How old was William Shirley when ordered reinforcements for the then-besieged British garrison at Fort Anne in Annapolis Royal? Passage:Gorham's Rangers was one of the most famous and effective ranger units raised in the colonial North America. Formed by John Gorham, the unit served as the prototype for many subsequent ranger forces, including the better known Rogers' Rangers. The unit started out as a Massachusetts provincial auxiliary company, which means it was not part of the province's normal militia system. Recruited in the summer of 1744 at the start of King George's War, Governor William Shirley ordered the unit raised as reinforcements for the then-besieged British garrison at Fort Anne in Annapolis Royal. Over the next eight years the unit proved remarkably effective at suppressing Acadian and Mi'kmaq resistance to British rule in Nova Scotia and helped to both expand and secure the British sphere of influence in the region. Initially a sixty-man all-Indian company led by British colonial officers, the original Native American members of the unit were gradually replaced by Anglo-Americans and recent Scots and Irish immigrants and were a minority in the unit by the mid-1750s. The company were reconnaissance experts as well as renowned for their expertise at both water-borne operations and frontier guerrilla warfare. They were known for surprise amphibious raids on Acadian and Mi'kmaq coastal or riverine settlements, using large whaleboats, which carried between ten and fifteen rangers each. This small unit was the main British military force defending Nova Scotia from 1744 to 1749. The company became part of the British army and was expanded during the Seven Years' War and went on to play an important role in fighting in Nova Scotia as well as participating in many of the important campaigns of the war, particularly distinguishing itself at the Siege of Quebec in 1759.
