Input: Read this: Tracks of the Northern Pacific Railroad (NPR) reached Montana from the west in 1881 and from the east in 1882. However, the railroad played a major role in sparking tensions with Native American tribes in the 1870s. Jay Cooke, the NPR president launched major surveys into the Yellowstone valley in 1871, 1872 and 1873 which were challenged forcefully by the Sioux under chief Sitting Bull. These clashes, in part, contributed to the Panic of 1873 which delayed construction of the railroad into Montana. Surveys in 1874, 1875 and 1876 helped spark the Great Sioux War of 1876. The transcontinental NPR was completed on September 8, 1883, at Gold Creek.
Question: What years were the railroad challenged by Chief Sitting Bull?

Output: 1871, 1872 and 1873

QUES: The second and most dramatic boom and bust resulted from the Klondike Gold Rush, which ended the depression that had begun with the Panic of 1893; in a short time, Seattle became a major transportation center. On July 14, 1897, the S.S. Portland docked with its famed "ton of gold", and Seattle became the main transport and supply point for the miners in Alaska and the Yukon. Few of those working men found lasting wealth, however; it was Seattle's business of clothing the miners and feeding them salmon that panned out in the long run. Along with Seattle, other cities like Everett, Tacoma, Port Townsend, Bremerton, and Olympia, all in the Puget Sound region, became competitors for exchange, rather than mother lodes for extraction, of precious metals. The boom lasted well into the early part of the 20th century and funded many new Seattle companies and products. In 1907, 19-year-old James E. Casey borrowed $100 from a friend and founded the American Messenger Company (later UPS). Other Seattle companies founded during this period include Nordstrom and Eddie Bauer. Seattle brought in the Olmsted Brothers landscape architecture firm to design a system of parks and boulevards.

For whom was Seattle the main port of supply ?
What is the answer?
ANS: miners

QUES: In infrared photography, infrared filters are used to capture the near-infrared spectrum. Digital cameras often use infrared blockers. Cheaper digital cameras and camera phones have less effective filters and can "see" intense near-infrared, appearing as a bright purple-white color. This is especially pronounced when taking pictures of subjects near IR-bright areas (such as near a lamp), where the resulting infrared interference can wash out the image. There is also a technique called 'T-ray' imaging, which is imaging using far-infrared or terahertz radiation. Lack of bright sources can make terahertz photography more challenging than most other infrared imaging techniques. Recently T-ray imaging has been of considerable interest due to a number of new developments such as terahertz time-domain spectroscopy.
What device uses far-infrared or terahertz radiation?

Everton were founder members of the Premier League in 1992, but struggled to find the right manager. Howard Kendall had returned in 1990 but could not repeat his previous success, while his successor, Mike Walker, was statistically the least successful Everton manager to date. When former Everton player Joe Royle took over in 1994 the club's form started to improve; his first game in charge was a 20 victory over derby rivals Liverpool. Royle dragged Everton clear of relegation, leading the club to the FA Cup for the fifth time in its history, defeating Manchester United 10 in the final.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who replaced Howard Kendall as Everton's manager?
Ah, so.. Mike Walker

Question: Formerly, men not wearing military uniform wore knee breeches of an 18th-century design. Women's evening dress included obligatory trains and tiaras or feathers in their hair (or both). The dress code governing formal court uniform and dress has progressively relaxed. After World War I, when Queen Mary wished to follow fashion by raising her skirts a few inches from the ground, she requested a lady-in-waiting to shorten her own skirt first to gauge the king's reaction. King George V was horrified, so the queen kept her hemline unfashionably low. Following their accession in 1936, King George VI and his consort, Queen Elizabeth, allowed the hemline of daytime skirts to rise. Today, there is no official dress code. Most men invited to Buckingham Palace in the daytime choose to wear service uniform or lounge suits; a minority wear morning coats, and in the evening, depending on the formality of the occasion, black tie or white tie.
Try to answer this question if possible: From what century were men's knee breeches worn at Buckingham designed in?
Answer: 18th-century design

Problem: Following a tentative agreement on by December 1, on December 3, 2009, the parties announced that Comcast would buy a controlling 51% stake in NBCUniversal for $6.5 billion in cash and $7.3 billion in programming. GE would take over the remaining 49% stake in NBCUniversal, using $5.8 billion to buy out Vivendi's 20% minority stake in NBCUniversal. On January 18, 2011, the FCC approved the deal by a vote of 4 to 1. The sale was completed on January 28, 2011. In late December 2012, Comcast added the NBC peacock symbol to their new logo. On February 12, 2013, Comcast announced an intention to acquire the remaining 49% of General Electric's interest in NBCUniversal, which Comcast completed on March 19, 2013.
The FCC denied the deal by what vote?
