Problem: Please answer a question about the following article about Gramophone record:
Eventually the 12-inch (300 mm) 33 1⁄3 rpm LP prevailed as the predominant format for musical albums, and 10-inch LPs were no longer issued. The last Columbia Records reissue of any Frank Sinatra songs on a 10-inch LP record was an album called Hall of Fame, CL 2600, issued on October 26, 1956, containing six songs, one each by Tony Bennett, Rosemary Clooney, Johnnie Ray, Frank Sinatra, Doris Day, and Frankie Laine. The 10-inch LP however had a longer life in the United Kingdom, where important early British rock and roll albums such as Lonnie Donegan's Lonnie Donegan Showcase and Billy Fury's The Sound of Fury were released in that form. The 7-inch (175 mm) 45 rpm disc or "single" established a significant niche for shorter duration discs, typically containing one item on each side. The 45 rpm discs typically emulated the playing time of the former 78 rpm discs, while the 12-inch LP discs eventually provided up to one half-hour of recorded material per side.
Did the 45 rpm or 12 inch disc offer longer playing time?
A: 12-inch LP
Problem: Please answer a question about the following article about Beyoncé:
Beyoncé and husband Jay Z are friends with President Barack Obama and First Lady Michelle Obama. She performed "America the Beautiful" at the 2009 presidential inauguration, as well as "At Last" during the first inaugural dance at the Neighborhood Ball two days later. Beyoncé and Jay Z held a fundraiser at the latter's 40/40 Club in Manhattan for Obama's 2012 presidential campaign which raised $4 million. Beyoncé uploaded pictures of her paper ballot on Tumblr, confirming she had voted in support for the Democratic Party and to encourage others to do so. She also performed the American national anthem at his second inauguration, singing along with a pre-recorded track. She publicly endorsed same sex marriage on March 26, 2013, after the Supreme Court debate on California's Proposition 8. In July 2013, Beyoncé and Jay-Z attended a rally in response to the acquittal of George Zimmerman for the shooting of Trayvon Martin.
Beyonce and Jay-Z went to a rally for the acquittal of whom?
A: George Zimmerman
Problem: Please answer a question about the following article about Planck constant:
The gyromagnetic ratio γ is the constant of proportionality between the frequency ν of nuclear magnetic resonance (or electron paramagnetic resonance for electrons) and the applied magnetic field B: ν = γB. It is difficult to measure gyromagnetic ratios precisely because of the difficulties in precisely measuring B, but the value for protons in water at 7002298150000000000♠25 °C is known to better than one part per million. The protons are said to be "shielded" from the applied magnetic field by the electrons in the water molecule, the same effect that gives rise to chemical shift in NMR spectroscopy, and this is indicated by a prime on the symbol for the gyromagnetic ratio, γ′p. The gyromagnetic ratio is related to the shielded proton magnetic moment μ′p, the spin number I (I = 1⁄2 for protons) and the reduced Planck constant.
The gyromagnetic ratio is often difficult to determine due to difficulty accurately determining the value of what?
A: the applied magnetic field B
Problem: Please answer a question about the following article about British Empire:
The changing world order that the war had brought about, in particular the growth of the United States and Japan as naval powers, and the rise of independence movements in India and Ireland, caused a major reassessment of British imperial policy. Forced to choose between alignment with the United States or Japan, Britain opted not to renew its Japanese alliance and instead signed the 1922 Washington Naval Treaty, where Britain accepted naval parity with the United States. This decision was the source of much debate in Britain during the 1930s as militaristic governments took hold in Japan and Germany helped in part by the Great Depression, for it was feared that the empire could not survive a simultaneous attack by both nations. Although the issue of the empire's security was a serious concern in Britain, at the same time the empire was vital to the British economy.
British imperialism was being reconsidered in light of which territories' independence movements?
A:
India and Ireland
