Context and question: Chopin's relations with Sand were soured in 1846 by problems involving her daughter Solange and Solange's fiance, the young fortune-hunting sculptor Auguste Clesinger. The composer frequently took Solange's side in quarrels with her mother; he also faced jealousy from Sand's son Maurice. Chopin was utterly indifferent to Sand's radical political pursuits, while Sand looked on his society friends with disdain. As the composer's illness progressed, Sand had become less of a lover and more of a nurse to Chopin, whom she called her "third child". In letters to third parties, she vented her impatience, referring to him as a "child," a "little angel", a "sufferer" and a "beloved little corpse." In 1847 Sand published her novel Lucrezia Floriani, whose main charactersa rich actress and a prince in weak healthcould be interpreted as Sand and Chopin; the story was uncomplimentary to Chopin, who could not have missed the allusions as he helped Sand correct the printer's galleys. In 1847 he did not visit Nohant, and he quietly ended their ten-year relationship following an angry correspondence which, in Sand's words, made "a strange conclusion to nine years of exclusive friendship." The two would never meet again.
When did Chopin end his relationship with Sand?
Answer: 1847
Context and question: Burrel's innovative design, which combined the low production cost of an Apple II with the computing power of Lisa's CPU, the Motorola 68K, received the attention of Steve Jobs, co-founder of Apple. Realizing that the Macintosh was more marketable than the Lisa, he began to focus his attention on the project. Raskin left the team in 1981 over a personality conflict with Jobs. Team member Andy Hertzfeld said that the final Macintosh design is closer to Jobs' ideas than Raskin's. After hearing of the pioneering GUI technology being developed at Xerox PARC, Jobs had negotiated a visit to see the Xerox Alto computer and its Smalltalk development tools in exchange for Apple stock options. The Lisa and Macintosh user interfaces were influenced by technology seen at Xerox PARC and were combined with the Macintosh group's own ideas. Jobs also commissioned industrial designer Hartmut Esslinger to work on the Macintosh line, resulting in the "Snow White" design language; although it came too late for the earliest Macs, it was implemented in most other mid- to late-1980s Apple computers. However, Jobs' leadership at the Macintosh project did not last; after an internal power struggle with new CEO John Sculley, Jobs resigned from Apple in 1985. He went on to found NeXT, another computer company targeting the education market, and did not return until 1997, when Apple acquired NeXT.
What didn't Steve Jobs offer Xerox to visit and see their latest technology?

Context and 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.
At what temperature range in degrees Fahrenheit won't uranium metal form uranium hydride?
Answer:
unanswerable
