Q: Question: "What allows a calculation of ratio of yes to no votes?" Context: "On October 25, 1989, the Supreme Soviet voted to eliminate special seats for the Communist Party and other official organizations in national and local elections, responding to sharp popular criticism that such reserved slots were undemocratic. After vigorous debate, the 542-member Supreme Soviet passed the measure 254-85 (with 36 abstentions). The decision required a constitutional amendment, ratified by the full congress, which met December 1225. It also passed measures that would allow direct elections for presidents of each of the 15 constituent republics. Gorbachev strongly opposed such a move during debate but was defeated." Answer:
A: 254-85

Q: Question: "What is an advantage of the changes?" Context: "Since the Industrial Revolution some two hundred years ago, the food processing industry has invented many technologies that both help keep foods fresh longer and alter the fresh state of food as they appear in nature. Cooling is the primary technology used to maintain freshness, whereas many more technologies have been invented to allow foods to last longer without becoming spoiled. These latter technologies include pasteurisation, autoclavation, drying, salting, and separation of various components, all of which appearing to alter the original nutritional contents of food. Pasteurisation and autoclavation (heating techniques) have no doubt improved the safety of many common foods, preventing epidemics of bacterial infection. But some of the (new) food processing technologies have downfalls as well." Answer:
A: foods to last longer without becoming spoiled

Q: Question: "Indian reservations were created by what types of documents?" Context: "Approximately 66,000 people of Native American heritage live in Montana. Stemming from multiple treaties and federal legislation, including the Indian Appropriations Act (1851), the Dawes Act (1887), and the Indian Reorganization Act (1934), seven Indian reservations, encompassing eleven tribal nations, were created in Montana. A twelfth nation, the Little Shell Chippewa is a "landless" people headquartered in Great Falls, recognized by the state of Montana but not by the U.S. Government. The Blackfeet nation is headquartered on the Blackfeet Indian Reservation (1851) in Browning, Crow on the Crow Indian Reservation (1851) in Crow Agency, Confederated Salish and Kootenai and Pend d'Oreille on the Flathead Indian Reservation (1855) in Pablo, Northern Cheyenne on the Northern Cheyenne Indian Reservation (1884) at Lame Deer, Assiniboine and Gros Ventre on the Fort Belknap Indian Reservation (1888) in Fort Belknap Agency, Assiniboine and Sioux on the Fort Peck Indian Reservation (1888) at Poplar, and Chippewa-Cree on the Rocky Boy's Indian Reservation (1916) near Box Elder. Approximately 63% of all Native people live off the reservations, concentrated in the larger Montana cities with the largest concentration of urban Indians in Great Falls. The state also has a small Metis population, and 1990 census data indicated that people from as many as 275 different tribes lived in Montana." Answer:
