Input: Read this: By 1790, the Jewish population of Alsace was approximately 22,500, about 3% of the provincial population. They were highly segregated and subject to long-standing anti-Jewish regulations. They maintained their own customs, Yiddish language, and historic traditions within the tightly-knit ghettos; they adhered to Talmudic law enforced by their rabbis. Jews were barred from most cities and instead lived in villages. They concentrated in trade, services, and especially in money lending. They financed about a third of the mortgages in Alsace. Official tolerance grew during the French Revolution, with full emancipation in 1791. However, local antisemitism also increased and Napoleon turned hostile in 1806, imposing a one-year moratorium on all debts owed to Jews.[citation needed] In the 1830-1870 era most Jews moved to the cities, where they integrated and acculturated, as antisemitism sharply declined. By 1831, the state began paying salaries to official rabbis, and in 1846 a special legal oath for Jews was discontinued. Antisemitic local riots occasionally occurred, especially during the Revolution of 1848. Merger of Alsace into Germany in 1871-1918 lessened antisemitic violence.
Question: Who did Alsace separate from in 1871?

Output: unanswerable

QUES: In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries' energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating global warming, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared".

What effect will solar energy have on the price of fossil fuels?
What is the answer?
ANS: keep fossil fuel prices lower than otherwise

QUES: The concept of blackness in the United States has been described as the degree to which one associates themselves with mainstream African-American culture, politics, and values. To a certain extent, this concept is not so much about race but more about political orientation, culture and behavior. Blackness can be contrasted with "acting white", where black Americans are said to behave with assumed characteristics of stereotypical white Americans with regard to fashion, dialect, taste in music, and possibly, from the perspective of a significant number of black youth, academic achievement.
How is blackness described in the US?

ANS: the degree to which one associates themselves with mainstream African-American culture, politics, and values.

Often categorised with the New Wave of British Heavy Metal, in 1981 Def Leppard released their second album High 'n' Dry, mixing glam-rock with heavy metal, and helping to define the sound of hard rock for the decade. The follow-up Pyromania (1983), reached number two on the American charts and the singles "Photograph", "Rock of Ages" and "Foolin'", helped by the emergence of MTV, all reached the Top 40. It was widely emulated, particularly by the emerging Californian glam metal scene. This was followed by US acts like Motley Crue, with their albums Too Fast for Love (1981) and Shout at the Devil (1983) and, as the style grew, the arrival of bands such as Ratt, White Lion, Twisted Sister and Quiet Riot. Quiet Riot's album Metal Health (1983) was the first glam metal album, and arguably the first heavy metal album of any kind, to reach number one in the Billboard music charts and helped open the doors for mainstream success by subsequent bands.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What sub-genre of hard rock does Def Leppard belong to?
Ah, so.. the New Wave of British Heavy Metal

Question: Uranium metal heated to 250 to 300 C (482 to 572 F) reacts with hydrogen to form uranium hydride. Even higher temperatures will reversibly remove the hydrogen. This property makes uranium hydrides convenient starting materials to create reactive uranium powder along with various uranium carbide, nitride, and halide compounds. Two crystal modifications of uranium hydride exist: an form that is obtained at low temperatures and a form that is created when the formation temperature is above 250 C.
Try to answer this question if possible: What doesn't uranium metal react with to create uranium hydride?
Answer: unanswerable

Input: Read this: The following week, John Edwards won the South Carolina primary and finished a strong second in Oklahoma to Clark. Lieberman dropped out of the campaign the following day. Kerry dominated throughout February and his support quickly snowballed as he won caucuses and primaries, taking in a string of wins in Michigan, Washington, Maine, Tennessee, Washington, D.C., Nevada, Wisconsin, Utah, Hawaii, and Idaho. Clark and Dean dropped out during this time, leaving Edwards as the only real threat to Kerry. Kucinich and Sharpton continued to run despite poor results at the polls.
Question: Which candidate won the Oklahoma primary?

Output:
Clark
