Problem: Please answer a question about the following article about Lighting:
Color temperature for white light sources also affects their use for certain applications. The color temperature of a white light source is the temperature in Kelvin of a theoretical black body emitter that most closely matches the spectral characteristics of the lamp. An incandescent bulb has a color temperature around 2800 to 3000 Kelvin; daylight is around 6400 Kelvin. Lower color temperature lamps have relatively more energy in the yellow and red part of the visible spectrum, while high color temperatures correspond to lamps with more of a blue-white appearance. For critical inspection or color matching tasks, or for retail displays of food and clothing, the color temperature of the lamps will be selected for the best overall lighting effect.
What has a color temperature around 2800 to 3000 Kelvin?
A: incandescent bulb

Among regional schools the MBA program was ranked No. 1 by The Wall Street Journal's most recent ranking (2007), and it was ranked No. 92 among business schools worldwide in 2009 by Financial Times. For 2009, the university's School of Accountancy, which is housed within the Marriott School, received two No. 3 rankings for its undergraduate programone by Public Accounting Report and the other by U.S. News & World Report. The same two reporting agencies also ranked the school's MAcc program No. 3 and No. 8 in the nation, respectively. In 2010, an article in the Wall Street Journal listing institutions whose graduates were the top-rated by recruiters ranked BYU No. 11. Using 2010 fiscal year data, the Association of University Technology Managers ranked BYU No. 3 in an evaluation of universities creating the most startup companies through campus research.

Who ranked BYU's MBA program No. 1 among regional schools in 2007?
Answer: The Wall Street Journal

Problem: Until the period following World War I the Near East and the Middle East coexisted, but they were not always seen as distinct. Bertram Lenox Simpson, a colonial officer killed eventually in China, uses the terms together in his 1910 book, The Conflict of Color, as "the Near and Middle East." The total super-region consisted of "India, Afghanistan, Persia, Arabistan, Asia Minor, and last, but not least, Egypt." Simpson (under his pen-name, Weale) explains that this entire region "is politically one region in spite of the divisions into which it is academically divided." His own term revives "the Nearer East" as opposed to "the Far East."
Who was the colonial officer killed in China?
The answer is the following: Bertram Lenox Simpson

In the 1960s, the first Nanjing Yangtze River Bridge was completed, and served as the only bridge crossing over the Lower Yangtze in eastern China at that time. The bridge was a source of pride and an important symbol of modern China, having been built and designed by the Chinese themselves following failed surveys by other nations and the reliance on and then rejection of Soviet expertise. Begun in 1960 and opened to traffic in 1968, the bridge is a two-tiered road and rail design spanning 4,600 metres on the upper deck, with approximately 1,580 metres spanning the river itself. Since then four more bridges and two tunnels have been built. Going in the downstream direction, the Yangtze crossings in Nanjing are: Dashengguan Bridge, Line 10 Metro Tunnel, Third Bridge, Nanjing Yangtze River Tunnel, First Bridge, Second Bridge and Fourth Bridge.
When did the Nanjing Yangtze River Bridge first open for traffic?
1968

Input: Muammar Gaddafi
The influence of Nasser's Arab nationalism over the RCC was immediately apparent. The administration was instantly recognized by the neighbouring Arab nationalist regimes in Egypt, Syria, Iraq and Sudan, with Egypt sending experts to aid the inexperienced RCC. Gaddafi propounded Pan-Arab ideas, proclaiming the need for a single Arab state stretching across North Africa and the Middle East. In December 1969, Libya founded the Arab Revolutionary Front with Egypt and Sudan as a step towards political unification, and in 1970 Syria stated its intention to join.

What philosophy influenced the RCC?
Output: Arab nationalism

Problem: Please answer a question about the following article about Compact disc:
The most expensive part of a CD is the jewel case. In 1995, material costs were 30 cents for the jewel case and 10 to 15 cents for the CD. Wholesale cost of CDs was $0.75 to $1.15, which retailed for $16.98. On average, the store received 35 percent of the retail price, the record company 27 percent, the artist 16 percent, the manufacturer 13 percent, and the distributor 9 percent. When 8-track tapes, cassette tapes, and CDs were introduced, each was marketed at a higher price than the format they succeeded, even though the cost to produce the media was reduced. This was done because the apparent value increased. This continued from vinyl to CDs but was broken when Apple marketed MP3s for $0.99, and albums for $9.99. The incremental cost, though, to produce an MP3 is very small.
How much did a jewel case cost in 1995?
A:
30 cents
