The problem: Answer a question about this article:
As with the minerals discussed above, some vitamins are recognized as organic essential nutrients, necessary in the diet for good health. (Vitamin D is the exception: it can be synthesized in the skin, in the presence of UVB radiation.) Certain vitamin-like compounds that are recommended in the diet, such as carnitine, are thought useful for survival and health, but these are not "essential" dietary nutrients because the human body has some capacity to produce them from other compounds. Moreover, thousands of different phytochemicals have recently been discovered in food (particularly in fresh vegetables), which may have desirable properties including antioxidant activity (see below); however, experimental demonstration has been suggestive but inconclusive. Other essential nutrients that are not classified as vitamins include essential amino acids (see above), choline, essential fatty acids (see above), and the minerals discussed in the preceding section.
What is choline not an example of?
****
The answer: vitamins

Problem: Please answer a question about the following article about Houston:
By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton. Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont. During the American Civil War, Houston served as a headquarters for General John Bankhead Magruder, who used the city as an organization point for the Battle of Galveston. After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas.
What was Houston known for by 1890?
A: railroad center of Texas

From January 1820, 2010 a national conference on Tibet and areas inhabited by Tibetans in Sichuan, Yunnan, Gansu and Qinghai was held in China and a substantial plan to improve development of the areas was announced. The conference was attended by General secretary Hu Jintao, Wu Bangguo, Wen Jiabao, Jia Qinglin, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang, all members of CPC Politburo Standing Committee signaling the commitment of senior Chinese leaders to development of Tibet and ethnic Tibetan areas. The plan calls for improvement of rural Tibetan income to national standards by 2020 and free education for all rural Tibetan children. China has invested 310 billion yuan (about 45.6 billion U.S. dollars) in Tibet since 2001. "Tibet's GDP was expected to reach 43.7 billion yuan in 2009, up 170 percent from that in 2000 and posting an annual growth of 12.3 percent over the past nine years."

How much, in US dollars, has China invested in Tibet since 2001?
Answer: about 45.6 billion

Problem: On 20 June 1794, Burke received a vote of thanks from the Commons for his services in the Hastings Trial and he immediately resigned his seat, being replaced by his son Richard. A tragic blow fell upon Burke with the loss of Richard in August 1794, to whom he was tenderly attached, and in whom he saw signs of promise, which were not patent to others and which, in fact, appear to have been non-existent (though this view may have rather reflected the fact that Richard Burke had worked successfully in the early battle for Catholic emancipation). King George III, whose favour he had gained by his attitude on the French Revolution, wished to create him Earl of Beaconsfield, but the death of his son deprived the opportunity of such an honour and all its attractions, so the only award he would accept was a pension of 2,500. Even this modest reward was attacked by the Duke of Bedford and the Earl of Lauderdale, to whom Burke replied in his Letter to a Noble Lord (1796): "It cannot at this time be too often repeated; line upon line; precept upon precept; until it comes into the currency of a proverb, To innovate is not to reform". He argued that he was rewarded on merit, but the Duke of Bedford received his rewards from inheritance alone, his ancestor being the original pensioner: "Mine was from a mild and benevolent sovereign; his from Henry the Eighth". Burke also hinted at what would happen to such people if their revolutionary ideas were implemented, and included a description of the British constitution:
How much money did Burke accept instead of the Earlship?
The answer is the following: 2,500

The BBC reported that France was the first journalist to face trial and be convicted under Operation Elveden since the Crown Prosecution Service (CPS) had revised its guidance in April 2015 so that prosecutions would only be brought against journalists who had made payments to police officers over a period of time. As a result of the change in the CPS' policy, charges against several journalists who had made payments to other types of public officials including civil servants, health workers and prison staff - had been dropped. In July 2015, Private Eye magazine reported that at a costs hearing at the Old Bailey The Sun's parent company had refused to pay for the prosecution costs relating to France's trial, leading the presiding judge to express his "considerable disappointment" at this state of affairs. Judge Timothy Pontius said in court that France's illegal actions had been part of a "clearly recognised procedure at The Sun", adding that, "There can be no doubt that News International bears some measure of moral responsibility if not legal culpability for the acts of the defendant". The Private Eye report noted that despite this The Sun's parent organisation was "considering disciplinary actions" against France whilst at the same time it was also preparing to bring a case to the Investigatory Powers Tribunal against the London Metropolitan Police Service for its actions relating to him and two other journalists.
Who else did Judge Pontius believe should be blamed for France's actions?
News International

Here is a question about this article: In 2007, the country with the highest estimated incidence rate of TB was Swaziland, with 1,200 cases per 100,000 people. India had the largest total incidence, with an estimated 2.0 million new cases. In developed countries, tuberculosis is less common and is found mainly in urban areas. Rates per 100,000 people in different areas of the world were: globally 178, Africa 332, the Americas 36, Eastern Mediterranean 173, Europe 63, Southeast Asia 278, and Western Pacific 139 in 2010. In Canada and Australia, tuberculosis is many times more common among the aboriginal peoples, especially in remote areas. In the United States Native Americans have a fivefold greater mortality from TB, and racial and ethnic minorities accounted for 84% of all reported TB cases.
What is the answer to this question: Out of every 100,000 people in Swaziland in 2007, how many were infected with tuberculosis?
****
