Problem: Please answer a question about the following article about Nutrition:
Cancer is now common in developing countries. According to a study by the International Agency for Research on Cancer, "In the developing world, cancers of the liver, stomach and esophagus were more common, often linked to consumption of carcinogenic preserved foods, such as smoked or salted food, and parasitic infections that attack organs." Lung cancer rates are rising rapidly in poorer nations because of increased use of tobacco. Developed countries "tended to have cancers linked to affluence or a 'Western lifestyle' — cancers of the colon, rectum, breast and prostate — that can be caused by obesity, lack of exercise, diet and age."
Which organization did a study on cancer in developing countries?
A: International Agency for Research on Cancer


Question: Read this and answer the question

Chopin's successes as a composer and performer opened the door to western Europe for him, and on 2 November 1830, he set out, in the words of Zdzisław Jachimecki, "into the wide world, with no very clearly defined aim, forever." With Woyciechowski, he headed for Austria, intending to go on to Italy. Later that month, in Warsaw, the November 1830 Uprising broke out, and Woyciechowski returned to Poland to enlist. Chopin, now alone in Vienna, was nostalgic for his homeland, and wrote to a friend, "I curse the moment of my departure." When in September 1831 he learned, while travelling from Vienna to Paris, that the uprising had been crushed, he expressed his anguish in the pages of his private journal: "Oh God! ... You are there, and yet you do not take vengeance!" Jachimecki ascribes to these events the composer's maturing "into an inspired national bard who intuited the past, present and future of his native Poland."

Who did Chopin leave for Austria with?
Answer: Woyciechowski


Problem: The theory that race is merely a social construct has been challenged by the findings of researchers at the Stanford University School of Medicine, published in the American Journal of Human Genetics as "Genetic Structure, Self-Identified Race/Ethnicity, and Confounding in Case-Control Association Studies". One of the researchers, Neil Risch, noted: "we looked at the correlation between genetic structure [based on microsatellite markers] versus self-description, we found 99.9% concordance between the two. We actually had a higher discordance rate between self-reported sex and markers on the X chromosome! So you could argue that sex is also a problematic category. And there are differences between sex and gender; self-identification may not be correlated with biology perfectly. And there is sexism."
Neil Risch found a 99.9% agree between genetic structure and people's description of their what?
The answer is the following: self


Tennessee is known as the "Volunteer State", a nickname some claimed was earned during the War of 1812 because of the prominent role played by volunteer soldiers from Tennessee, especially during the Battle of New Orleans. Other sources differ on the origin of the state nickname; according to the Columbia Encyclopedia, the name refers to volunteers for the Mexican–American War. This explanation is more likely, because President Polk's call for 2,600 nationwide volunteers at the beginning of the Mexican-American War resulted in 30,000 volunteers from Tennessee alone, largely in response to the death of Davy Crockett and appeals by former Tennessee Governor and now Texas politician, Sam Houston.
How many volunteers did Tennessee send to the Mexican-American War?
30,000
