Input: Article: Three Han mathematical treatises still exist. These are the Book on Numbers and Computation, the Arithmetical Classic of the Gnomon and the Circular Paths of Heaven and the Nine Chapters on the Mathematical Art. Han-era mathematical achievements include solving problems with right-angle triangles, square roots, cube roots, and matrix methods, finding more accurate approximations for pi, providing mathematical proof of the Pythagorean theorem, use of the decimal fraction, Gaussian elimination to solve linear equations, and continued fractions to find the roots of equations.

Now answer this question: What achievement of the Han era can be used to help solve linear equations?

Output: Gaussian elimination


Article: The San Diego Surf of the American Basketball Association is located in the city. The annual Farmers Insurance Open golf tournament (formerly the Buick Invitational) on the PGA Tour occurs at Torrey Pines Golf Course. This course was also the site of the 2008 U.S. Open Golf Championship. The San Diego Yacht Club hosted the America's Cup yacht races three times during the period 1988 to 1995. The amateur beach sport Over-the-line was invented in San Diego, and the annual world Over-the-line championships are held at Mission Bay every year.

Question: How many times were the America's Cup yacht races hosted by the San Diego Yacht Club from 1988 to 1955?
Ans: three times


Here is a question about this article: In a study published in the Journal of Behavioural and Experimental Economics, and reported on in early May 2014, researchers from the University of Portsmouth in the UK discussed findings from examining the illegal downloading behavior of 6,000 Finnish people, aged seven to 84. The list of reasons for downloading given by the study respondents included money saving; the ability to access material not on general release, or before it was released; and assisting artists to avoid involvement with record companies and movie studios.
What is the answer to this question: How many people were part of the study?
****
So... 6,000


The problem: Answer a question about this article:
"The first Ottoman Medrese was created in İznik in 1331 and most Ottoman medreses followed the traditions of Sunni Islam." "When an Ottoman sultan established a new medrese, he would invite scholars from the Islamic world—for example, Murad II brought scholars from Persia, such as ʻAlāʼ al-Dīn and Fakhr al-Dīn who helped enhance the reputation of the Ottoman medrese". This reveals that the Islamic world was interconnected in the early modern period as they travelled around to other Islamic states exchanging knowledge. This sense that the Ottoman Empire was becoming modernised through globalization is also recognised by Hamadeh who says: "Change in the eighteenth century as the beginning of a long and unilinear march toward westernisation reflects the two centuries of reformation in sovereign identity." İnalcık also mentions that while scholars from for example Persia travelled to the Ottomans in order to share their knowledge, Ottomans travelled as well to receive education from scholars of these Islamic lands, such as Egypt, Persia and Turkestan. Hence, this reveals that similar to today's modern world, individuals from the early modern society travelled abroad to receive education and share knowledge and that the world was more interconnected than it seems. Also, it reveals how the system of "schooling" was also similar to today's modern world where students travel abroad to different countries for studies. Examples of Ottoman madaris are the ones built by Mehmed the Conqueror. He built eight madaris that were built "on either side of the mosque where there were eight higher madaris for specialised studies and eight lower medreses, which prepared students for these." The fact that they were built around, or near mosques reveals the religious impulses behind madrasa building and it reveals the interconnectedness between institutions of learning and religion. The students who completed their education in the lower medreses became known as danismends. This reveals that similar to the education system today, the Ottomans' educational system involved different kinds of schools attached to different kinds of levels. For example, there were lower madaris and specialised ones, and for one to get into the specialised area meant that he had to complete the classes in the lower one in order to adequately prepare himself for higher learning.
How would a student matriculate to the next level of schooling in the Ottoman Empire?
****
The answer: complete the classes in the lower one


Problem: Please answer a question about the following article about Affirmative action in the United States:
A study in 2007 by Mark Long, an economics professor at the University of Washington, demonstrated that the alternatives of affirmative action proved ineffective in restoring minority enrollment in public flagship universities in California, Texas, and Washington. More specifically, apparent rebounds of minority enrollment can be explained by increasing minority enrollment in high schools of those states, and the beneficiaries of class-based (not race) affirmative action would be white students. At the same time, affirmative action itself is both morally and materially costly: 52 percent of white populace (compared to 14 percent of black) thought it should be abolished, implying white distaste of using racial identity, and full-file review is expected to cost the universities an additional $1.5 million to $2 million per year, excluding possible cost of litigation.
In which year did Long publish his study?
A: 2007


Question: Read this and answer the question

In May 1985, Gorbachev delivered a speech in Leningrad advocating reforms and an anti-alcohol campaign to tackle widespread alcoholism. Prices on vodka, wine, and beer were raised in order to make these drinks more expensive and a disincentive to consumers, and the introduction of rationing. Unlike most forms of rationing intended to conserve scarce goods, this was done to restrict sales with the overt goal of curtailing drunkenness. Gorbachev's plan also included billboards promoting sobriety, increased penalties for public drunkenness, and to censor drinking scenes from old movies. Although this program was not a direct copycat of Tsar Nicholas II's outright prohibition during World War I, Gorbachev faced the same adverse economic reaction as did the last Tsar. The disincentivization of alcohol consumption was a serious blow to the state budget according to Alexander Yakovlev, who noted annual collections of alcohol taxes decreased by 100 billion rubles. Alcohol production migrated to the black market, or through moonshining as some made "bathtub vodka" with homegrown potatoes. Poorer, less educated Russians resorted to drinking unhealthy substitutes such as nail polish, rubbing alcohol or men's cologne, which only served to be an additional burden on Russia's healthcare sector due to the subsequent poisoning cases. The purpose of these reforms, however, was to prop up the existing centrally planned economy, unlike later reforms, which tended toward market socialism.

Whose anti-alcohol program did Gorbachev's remind people of?
Answer:
Tsar Nicholas II
