Here is a question about this article: Zinc(I) compounds are rare, and require bulky ligands to stabilize the low oxidation state. Most zinc(I) compounds contain formally the [Zn2]2+ core, which is analogous to the [Hg2]2+ dimeric cation present in mercury(I) compounds. The diamagnetic nature of the ion confirms its dimeric structure. The first zinc(I) compound containing the Zn—Zn bond, (η5-C5Me5)2Zn2, is also the first dimetallocene. The [Zn2]2+ ion rapidly disproportionates into zinc metal and zinc(II), and has only been obtained as a yellow glass formed by cooling a solution of metallic zinc in molten ZnCl2.
What is the answer to this question: What core do most zinc(l) compounds contain?
****
So... [Zn2]2+


The problem: Answer a question about this article:
The strength of the Viking influence on Old English appears from the fact that the indispensable elements of the language - pronouns, modals, comparatives, pronominal adverbs (like "hence" and "together"), conjunctions and prepositions - show the most marked Danish influence; the best evidence of Scandinavian influence appears in the extensive word borrowings for, as Jespersen indicates, no texts exist in either Scandinavia or in Northern England from this time to give certain evidence of an influence on syntax. The change to Old English from Old Norse was substantive, pervasive, and of a democratic character. Old Norse and Old English resembled each other closely like cousins and with some words in common, they roughly understood each other; in time the inflections melted away and the analytic pattern emerged. It is most “important to recognize that in many words the English and Scandinavian language differed chiefly in their inflectional elements. The body of the word was so nearly the same in the two languages that only the endings would put obstacles in the way of mutual understanding. In the mixed population which existed in the Danelaw these endings must have led to much confusion, tending gradually to become obscured and finally lost.” This blending of peoples and languages happily resulted in “simplifying English grammar.”
What language was spoken in Northern England after the Viking invasions?
****
The answer: Old Norse


Problem: Please answer a question about the following article about Alaska:
One of the most prominent movies filmed in Alaska is MGM's Eskimo/Mala The Magnificent, starring Alaska Native Ray Mala. In 1932 an expedition set out from MGM's studios in Hollywood to Alaska to film what was then billed as "The Biggest Picture Ever Made." Upon arriving in Alaska, they set up "Camp Hollywood" in Northwest Alaska, where they lived during the duration of the filming. Louis B. Mayer spared no expense in spite of the remote location, going so far as to hire the chef from the Hotel Roosevelt in Hollywood to prepare meals.
Which Alaskan native starred in a film also set in Alaska?
A: Ray Mala


Question: Read this and answer the question

In 1992, Madonna had a role in A League of Their Own as Mae Mordabito, a baseball player on an all-women's team. She recorded the film's theme song, "This Used to Be My Playground", which became a Hot 100 number one hit. The same year, she founded her own entertainment company, Maverick, consisting of a record company (Maverick Records), a film production company (Maverick Films), and associated music publishing, television broadcasting, book publishing and merchandising divisions. The deal was a joint venture with Time Warner and paid Madonna an advance of $60 million. It gave her 20% royalties from the music proceedings, one of the highest rates in the industry, equaled at that time only by Michael Jackson's royalty rate established a year earlier with Sony. The first release from the venture was Madonna's book, titled Sex. It consisted of sexually provocative and explicit images, photographed by Steven Meisel. The book received strong negative reaction from the media and the general public, but sold 1.5 million copies at $50 each in a matter of days. At the same time she released her fifth studio album, Erotica, which debuted at number two on the Billboard 200. Its title track peaked at number three on the Billboard Hot 100. Erotica also produced five singles: "Deeper and Deeper", "Bad Girl", "Fever", "Rain" and "Bye Bye Baby". Madonna had provocative imagery featured in the erotic thriller, Body of Evidence, a film which contained scenes of sadomasochism and bondage. It was poorly received by critics. She also starred in the film Dangerous Game, which was released straight to video in North America. The New York Times described the film as "angry and painful, and the pain feels real."

What was the name of the erotic thriller that shows scenes of sadomasochism and bondage?
Answer: Body of Evidence


Problem: Tajiks began to be conscripted into the Soviet Army in 1939 and during World War II around 260,000 Tajik citizens fought against Germany, Finland and Japan. Between 60,000(4%) and 120,000(8%) of Tajikistan's 1,530,000 citizens were killed during World War II. Following the war and Stalin's reign attempts were made to further expand the agriculture and industry of Tajikistan. During 1957–58 Nikita Khrushchev's Virgin Lands Campaign focused attention on Tajikistan, where living conditions, education and industry lagged behind the other Soviet Republics. In the 1980s, Tajikistan had the lowest household saving rate in the USSR, the lowest percentage of households in the two top per capita income groups, and the lowest rate of university graduates per 1000 people. By the late 1980s Tajik nationalists were calling for increased rights. Real disturbances did not occur within the republic until 1990. The following year, the Soviet Union collapsed, and Tajikistan declared its independence.
What percent of Tajiks were killed during the war?
The answer is the following: Between 60,000(4%) and 120,000(8%)


Input: Article: The onset of symptoms in myocardial infarction (MI) is usually gradual, over several minutes, and rarely instantaneous. Chest pain is the most common symptom of acute MI and is often described as a sensation of tightness, pressure, or squeezing. Chest pain due to ischemia (a lack of blood and hence oxygen supply) of the heart muscle is termed angina pectoris. Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, back, and upper abdomen, where it may mimic heartburn. Levine's sign, in which a person localizes the chest pain by clenching their fists over their sternum, has classically been thought to be predictive of cardiac chest pain, although a prospective observational study showed it had a poor positive predictive value.

Now answer this question: What does the pain usually stem from with MI?

Output:
left arm
