Problem: Please answer a question about the following article about Planck constant:
The photoelectric effect is the emission of electrons (called "photoelectrons") from a surface when light is shone on it. It was first observed by Alexandre Edmond Becquerel in 1839, although credit is usually reserved for Heinrich Hertz, who published the first thorough investigation in 1887. Another particularly thorough investigation was published by Philipp Lenard in 1902. Einstein's 1905 paper discussing the effect in terms of light quanta would earn him the Nobel Prize in 1921, when his predictions had been confirmed by the experimental work of Robert Andrews Millikan. The Nobel committee awarded the prize for his work on the photo-electric effect, rather than relativity, both because of a bias against purely theoretical physics not grounded in discovery or experiment, and dissent amongst its members as to the actual proof that relativity was real.
Einstein's paper on the photoelectric effect earned him the Nobel Prize in what year?
A: 1921
Problem: Please answer a question about the following article about 2008 Summer Olympics torch relay:
Of the 80 torch-bearers in London, Sir Steve Redgrave, who started the relay, mentioned to the media that he had received e-mailed pleas to boycott the event and could "see why they would like to make an issue" of it. Francesca Martinez and Richard Vaughan refused to carry the torch, while Konnie Huq decided to carry it and also speak out against China. The pro-Tibetan Member of Parliament Norman Baker asked all bearers to reconsider. Amid pressure from both directions, Prime Minister Gordon Brown welcomed the torch outside 10 Downing Street without holding or touching it. The London relay saw the torch surrounded by what the BBC described as "a mobile protective ring." Protests began as soon as Redgrave started the event, leading to at least thirty-five arrests. In Ladbroke Grove a demonstrator attempted to snatch the torch from Konnie Huq in a momentary struggle, and in a separate incident, a fire extinguisher was set off near the torch. The Chinese ambassador carried the torch through Chinatown after an unpublicized change to the route amid security concerns. The torch made an unscheduled move onto a bus along Fleet Street amid security concerns and efforts to evade the protesters. In an effort to counter the pro-Tibet protesters and show their support for the 2008 Beijing Olympics, more than 2,000 Chinese also gathered on the torch route and demonstrated with signs, banners and Chinese flags. A large number of supporters were concentrated in Trafalgar Square, displaying the Olympic slogan "One World, One Dream".
What two people in England declined to bear the torch?
A: Francesca Martinez and Richard Vaughan
Problem: Please answer a question about the following article about United States Army:
The U.S. Army currently consists of 10 active divisions as well as several independent units. The force is in the process of contracting after several years of growth. In June 2013, the Army announced plans to downsize to 32 active combat brigade teams by 2015 to match a reduction in active duty strength to 490,000 soldiers. Army Chief of Staff Raymond Odierno has projected that by 2018 the Army will eventually shrink to "450,000 in the active component, 335,000 in the National Guard and 195,000 in U.S. Army Reserve."
How many brigade teams did the Army downsize to by 2015?
A:
32
