Question: 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.
Is there an answer to this question: What temperature does zinc become unbreakable?

Answer: unanswerable

Question: The Cherokee Nation instigated a 10-year language preservation plan that involved growing new fluent speakers of the Cherokee language from childhood on up through school immersion programs as well as a collaborative community effort to continue to use the language at home. This plan was part of an ambitious goal that in 50 years, 80% or more of the Cherokee people will be fluent in the language. The Cherokee Preservation Foundation has invested $3 million into opening schools, training teachers, and developing curricula for language education, as well as initiating community gatherings where the language can be actively used. There is a Cherokee language immersion school in Tahlequah, Oklahoma that educates students from pre-school through eighth grade. Graduates are fluent speakers of the language. Several universities offer Cherokee as a second language, including the University of Oklahoma and Northeastern State University.
Is there an answer to this question: Where is there a Cherokee immersion school?

Answer: Tahlequah, Oklahoma

Question: The history of the Seven Years' War in North America, particularly the expulsion of the Acadians, the siege of Quebec, the death of Wolfe, and the Battle of Fort William Henry generated a vast number of ballads, broadsides, images, and novels (see Longfellow's Evangeline, Benjamin West's The Death of General Wolfe, James Fenimore Cooper's The Last of the Mohicans), maps and other printed materials, which testify to how this event held the imagination of the British and North American public long after Wolfe's death in 1759.
