Article: Schwarzenegger's net worth had been conservatively estimated at $100$200 million. After separating from his wife, Maria Shriver, in 2011, it has been estimated that his net worth has been approximately $400 million, and even as high as $800 million, based on tax returns he filed in 2006. Over the years as an investor, he invested his bodybuilding and movie earnings in an array of stocks, bonds, privately controlled companies, and real estate holdings worldwide, making his net worth as an accurate estimation difficult to calculate, particularly in light of declining real estate values owing to economic recessions in the U.S. and Europe since the late 2000s. In June 1997, Schwarzenegger spent $38 million of his own money on a private Gulfstream jet. Schwarzenegger once said of his fortune, "Money doesn't make you happy. I now have $50 million, but I was just as happy when I had $48 million." He has also stated, "I've made many millions as a businessman many times over."

Question: What was the price tag for the private jet Schwarzenegger bought in 1997?
Ans: $38 million

Article: In September 2003, China intended to join the European Galileo positioning system project and was to invest 230 million (USD296 million, GBP160 million) in Galileo over the next few years. At the time, it was believed that China's "BeiDou" navigation system would then only be used by its armed forces. In October 2004, China officially joined the Galileo project by signing the Agreement on the Cooperation in the Galileo Program between the "Galileo Joint Undertaking" (GJU) and the "National Remote Sensing Centre of China" (NRSCC). Based on the Sino-European Cooperation Agreement on Galileo program, China Galileo Industries (CGI), the prime contractor of the China's involvement in Galileo programs, was founded in December 2004. By April 2006, eleven cooperation projects within the Galileo framework had been signed between China and EU. However, the Hong Kong-based South China Morning Post reported in January 2008 that China was unsatisfied with its role in the Galileo project and was to compete with Galileo in the Asian market.

Question: How much was China going to invest in the European Galileo positioning system project?
Ans: 230 million (USD296 million, GBP160 million)

Article: These developments led to the theory of conservation of energy, formalized largely by William Thomson (Lord Kelvin) as the field of thermodynamics. Thermodynamics aided the rapid development of explanations of chemical processes by Rudolf Clausius, Josiah Willard Gibbs, and Walther Nernst. It also led to a mathematical formulation of the concept of entropy by Clausius and to the introduction of laws of radiant energy by Jozef Stefan. According to Noether's theorem, the conservation of energy is a consequence of the fact that the laws of physics do not change over time. Thus, since 1918, theorists have understood that the law of conservation of energy is the direct mathematical consequence of the translational symmetry of the quantity conjugate to energy, namely time.

Question: What aided the rapid development of explanations of chemical processes by Clausius, Gibbs and Nernst?
Ans: Thermodynamics

Article: Just days before the relay supporters of Falun Gong demonstrated in front of the Chinese embassy in the Malaysian capital. As many as 1,000 personnel from the special police unit were expected to be deployed on the day of the relay. A Japanese family with Malaysian citizenship and their 5-year-old child who unfurled a Tibetan flag were hit by a group of Chinese nationals with plastic air-filled batons and heckled by a crowd of Chinese citizens during the confrontation at Independence Square where the relay began, and the Chinese group shouted: "Taiwan and Tibet belong to China." Later during the day, the Chinese volunteers forcefully took away placards from two other Malaysians protesting at the relay. One of the protesting Malaysian was hit in the head.

Question: What were a Japanese family who unveiled a Tibetan flag hit with?
Ans:
plastic air-filled batons
