Input: Read this: 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.
Question: What is the term for pain in the left arm?

Output: unanswerable


Input: Read this: Xiamen dialect, sometimes known as Amoy, is the main dialect spoken in the Chinese city of Xiamen and its surrounding regions of Tong'an and Xiang'an, both of which are now included in the Greater Xiamen area. This dialect developed in the late Ming dynasty when Xiamen was increasingly taking over Quanzhou's position as the main port of trade in southeastern China. Quanzhou traders began travelling southwards to Xiamen to carry on their businesses while Zhangzhou peasants began traveling northwards to Xiamen in search of job opportunities. It is at this time when a need for a common language arose. The Quanzhou and Zhangzhou varieties are similar in many ways (as can be seen from the common place of Henan Luoyang where they originated), but due to differences in accents, communication can be a problem. Quanzhou businessmen considered their speech to be the prestige accent and considered Zhangzhou's to be a village dialect. Over the centuries, dialect leveling occurred and the two speeches mixed to produce the Amoy dialect.
Question: During what dynasty did the Xiamen dialect develope?

Output: late Ming dynasty


Input: Read this: The Strumica Carnival (Macedonian: Струмички Карневал, translated Strumichki Karneval) has been held since at least 1670, when the Turkish author Evlija Chelebija wrote while staying there, "I came into a town located in the foothills of a high hillock and what I saw that night was masked people running house–to–house, with laughter, scream and song." The Carnival took an organized form in 1991; in 1994, Strumica became a member of FECC and in 1998 hosted the XVIII International Congress of Carnival Cities. The Strumica Carnival opens on a Saturday night at a masked ball where the Prince and Princess are chosen; the main Carnival night is on Tuesday, when masked participants (including groups from abroad) compete in various subjects. As of 2000, the Festival of Caricatures and Aphorisms has been held as part of Strumica's Carnival celebrations.
Question: What nationality was Evlija Chelebija?

Output: Turkish
