Input: Read this: Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 °C. Above 210 °C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has relatively low melting (419.5 °C) and boiling points (907 °C). Its melting point is the lowest of all the transition metals aside from mercury and cadmium.
Question: What happens to zinc when it is manipulated to the temperatures between 100 and 150 Celsius?

Output: becomes malleable


Input: Read this: As economic and demographic methods were applied to the study of history, the trend was increasingly to see the late Middle Ages as a period of recession and crisis. Belgian historian Henri Pirenne continued the subdivision of Early, High, and Late Middle Ages in the years around World War I. Yet it was his Dutch colleague, Johan Huizinga, who was primarily responsible for popularising the pessimistic view of the Late Middle Ages, with his book The Autumn of the Middle Ages (1919). To Huizinga, whose research focused on France and the Low Countries rather than Italy, despair and decline were the main themes, not rebirth.
Question: What methods, applied to the study of chemistry, led to the perception of the Middle Ages as a time of recession and crisis?

Output: unanswerable


Input: Read this: The 2000 U.S. Census in the write-in response category had a code listing which standardizes the placement of various write-in responses for automatic placement within the framework of the U.S. Census's enumerated races. Whereas most responses can be distinguished as falling into one of the five enumerated races, there remains some write-in responses which fall into the "Mixture" heading which cannot be racially categorized. These include "Bi Racial, Combination, Everything, Many, Mixed, Multi National, Multiple, Several and Various".
Question: What did the code listing destandardize?

Output:
unanswerable
