Question: In addition there are two service bells, cast by Robert Mot, in 1585 and 1598 respectively, a Sanctus bell cast in 1738 by Richard Phelps and Thomas Lester and two unused bells—one cast about 1320, by the successor to R de Wymbish, and a second cast in 1742, by Thomas Lester. The two service bells and the 1320 bell, along with a fourth small silver "dish bell", kept in the refectory, have been noted as being of historical importance by the Church Buildings Council of the Church of England.
Is there an answer to this question: When was the Sanctus bell ruined?

Answer: unanswerable


Question: With a total area of 147,040 square miles (380,800 km2), Montana is slightly larger than Japan. It is the fourth largest state in the United States after Alaska, Texas, and California; the largest landlocked U.S. state; and the 56th largest national state/province subdivision in the world. To the north, Montana shares a 545-mile (877 km) border with three Canadian provinces: British Columbia, Alberta, and Saskatchewan, the only state to do so. It borders North Dakota and South Dakota to the east, Wyoming to the south and Idaho to the west and southwest.
Is there an answer to this question: What state does it border to the west?

Answer: Idaho


Question: Kievan Rus' begins with the rule (882–912) of Prince Oleg, who extended his control from Novgorod south along the Dnieper river valley in order to protect trade from Khazar incursions from the east and moved his capital to the more strategic Kiev. Sviatoslav I (died 972) achieved the first major expansion of Kievan Rus' territorial control, fighting a war of conquest against the Khazar Empire. Vladimir the Great (980–1015) introduced Christianity with his own baptism and, by decree, that of all the inhabitants of Kiev and beyond. Kievan Rus' reached its greatest extent under Yaroslav I (1019–1054); his sons assembled and issued its first written legal code, the Rus' Justice, shortly after his death.
Is there an answer to this question: Who achieve the first major expansion of Kievan?

Answer: Kiev. Sviatoslav I


Question: The concept of emissivity is important in understanding the infrared emissions of objects. This is a property of a surface that describes how its thermal emissions deviate from the ideal of a black body. To further explain, two objects at the same physical temperature will not show the same infrared image if they have differing emissivity. For example, for any pre-set emissivity value, objects with higher emissivity will appear hotter, and those with a lower emissivity will appear cooler. For that reason, incorrect selection of emissivity will give inaccurate results when using infrared cameras and pyrometers.
Is there an answer to this question: What property describes how a surfaces thermal emissions give inaccurate results when using infrared cameras and pyrometers?

Answer:
unanswerable
