Problem: Race and ethnicity in the United States Census:

Race was asked differently in the Census 2000 in several other ways than previously. Most significantly, respondents were given the option of selecting one or more race categories to indicate racial identities. Data show that nearly seven million Americans identified as members of two or more races. Because of these changes, the Census 2000 data on race are not directly comparable with data from the 1990 census or earlier censuses. Use of caution is therefore recommended when interpreting changes in the racial composition of the US population over time.

What year was the last census before the Census 2000?
---
A: 1990


Problem: On September 9, 2007, West suggested that his race had something to do with his being overlooked for opening the 2007 MTV Video Music Awards (VMAs) in favor of Britney Spears; he claimed, "Maybe my skin’s not right." West was performing at the event; that night, he lost all five awards that he was nominated for, including Best Male Artist and Video of the Year. After the show, he was visibly upset that he had lost at the VMAs two years in a row, stating that he would not come back to MTV ever again. He also appeared on several radio stations saying that when he made the song "Stronger" that it was his dream to open the VMAs with it. He has also stated that Spears has not had a hit in a long period of time and that MTV exploited her for ratings.
What factor did Kanye West accuse of being the reason for his being excluded for the opening of the 2007 VMAs?

The Late Triassic spans from 237 million to 200 million years ago. Following the bloom of the Middle Triassic, the Late Triassic featured frequent heat spells, as well as moderate precipitation (10-20 inches per year). The recent warming led to a boom of reptilian evolution on land as the first true dinosaurs evolve, as well as pterosaurs. All this climatic change, however, resulted in a large die-out known as the Triassic-Jurassic extinction event, in which all archosaurs (excluding ancient crocodiles), most synapsids, and almost all large amphibians went extinct, as well as 34% of marine life in the fourth mass extinction event of the world. The cause is debatable.
What was the span of the Late Triassic?
A: 237 million to 200 million years


Context and question: On the Origin of Species was first published on Thursday 24 November 1859, priced at fifteen shillings with a first printing of 1250 copies. The book had been offered to booksellers at Murray's autumn sale on Tuesday 22 November, and all available copies had been taken up immediately. In total, 1,250 copies were printed but after deducting presentation and review copies, and five for Stationers' Hall copyright, around 1,170 copies were available for sale. Significantly, 500 were taken by Mudie's Library, ensuring that the book promptly reached a large number of subscribers to the library. The second edition of 3,000 copies was quickly brought out on 7 January 1860, and incorporated numerous corrections as well as a response to religious objections by the addition of a new epigraph on page ii, a quotation from Charles Kingsley, and the phrase "by the Creator" added to the closing sentence. During Darwin's lifetime the book went through six editions, with cumulative changes and revisions to deal with counter-arguments raised. The third edition came out in 1861, with a number of sentences rewritten or added and an introductory appendix, An Historical Sketch of the Recent Progress of Opinion on the Origin of Species, while the fourth in 1866 had further revisions. The fifth edition, published on 10 February 1869, incorporated more changes and for the first time included the phrase "survival of the fittest", which had been coined by the philosopher Herbert Spencer in his Principles of Biology (1864).
What was the cost for the first published copies of On the Origin of Species?
Answer: fifteen shillings


Question: Genre fiction also showed it could question reality in its 20th century forms, in spite of its fixed formulas, through the enquiries of the skeptical detective and the alternative realities of science fiction. The separation of "mainstream" and "genre" forms (including journalism) continued to blur during the period up to our own times. William Burroughs, in his early works, and Hunter S. Thompson expanded documentary reporting into strong subjective statements after the second World War, and post-modern critics have disparaged the idea of objective realism in general.
Is there an answer to this question: What are William Thompson and Hunter S. Burroughs known for?

Answer: unanswerable

Northwestern was elected to the Association of American Universities in 1917 and remains a research university with "very high" research activity. Northwestern's schools of management, engineering, and communication are among the most academically productive in the nation. Northwestern received $550 million in research funding in 2014. Northwestern supports nearly 1,500 research laboratories across two campuses, predominately in the medical and biological sciences. Through the Innovation and New Ventures Office (INVO), Northwestern researchers disclosed 247 inventions, filed 270 patents applications, received 81 foreign and US patents, started 12 companies, and generated $79.8 million in licensing revenue in 2013. The bulk of revenue has come from a patent on pregabalin, a synthesized organic molecule discovered by chemistry professor Richard Silverman, which ultimately was marketed as Lyrica, a drug sold by Pfizer, to combat epilepsy, neuropathic pain, and fibromyalgia. INVO has been involved in creating a number of centers, including the Center for Developmental Therapeutics (CDT) and the Center for Device Development (CD2). It has also helped form over 50 Northwestern startup companies based on Northwestern technologies.
Who discovered the drug that was ultimately marketed as Lyrica?
A:
chemistry professor Richard Silverman
