Problem: Pub:

Later, the public bars gradually improved until sometimes almost the only difference was in the prices, so that customers could choose between economy and exclusivity (or youth and age, or a jukebox or dartboard).[citation needed] With the blurring of class divisions in the 1960s and 1970s,[citation needed] the distinction between the saloon and the public bar was often seen as archaic,[citation needed] and was frequently abolished, usually by the removal of the dividing wall or partition.[citation needed] While the names of saloon and public bar may still be seen on the doors of pubs, the prices (and often the standard of furnishings and decoration) are the same throughout the premises, and many pubs now comprise one large room. However the modern importance of dining in pubs encourages some establishments to maintain distinct rooms or areas.

In what decades did class distinctions break down in Britain?
---
A: the 1960s and 1970s


Problem: While President Truman had begun the process of desegregating the Armed Forces in 1948, actual implementation had been slow. Eisenhower made clear his stance in his first State of the Union address in February 1953, saying "I propose to use whatever authority exists in the office of the President to end segregation in the District of Columbia, including the Federal Government, and any segregation in the Armed Forces". When he encountered opposition from the services, he used government control of military spending to force the change through, stating "Wherever Federal Funds are expended ..., I do not see how any American can justify ... a discrimination in the expenditure of those funds".
Which president initially began to desegregate the US military?
---
Answer: Truman


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A major turning point in the development of DC machines took place in 1864, when Antonio Pacinotti described for the first time the ring armature with its symmetrically grouped coils closed upon themselves and connected to the bars of a commutator, the brushes of which delivered practically non-fluctuating current. The first commercially successful DC motors followed the invention by Zénobe Gramme who, in 1871, reinvented Pacinotti's design. In 1873, Gramme showed that his dynamo could be used as a motor, which he demonstrated to great effect at exhibitions in Vienna and Philadelphia by connecting two such DC motors at a distance of up to 2 km away from each other, one as a generator. (See also 1873 : l'expérience décisive [Decisive Workaround] .)
How similar were the motors in Gramme's demonstrations?
A: unanswerable


Context and question: Native Alabamian Allen Barra sharply criticized Lee and the novel in The Wall Street Journal calling Atticus a "repository of cracker-barrel epigrams" and the novel represents a "sugar-coated myth" of Alabama history. Barra writes, "It's time to stop pretending that To Kill a Mockingbird is some kind of timeless classic that ranks with the great works of American literature. Its bloodless liberal humanism is sadly dated". Thomas Mallon in The New Yorker criticizes Atticus' stiff and self-righteous demeanor, and calls Scout "a kind of highly constructed doll" whose speech and actions are improbable. Although acknowledging that the novel works, Mallon blasts Lee's "wildly unstable" narrative voice for developing a story about a content neighborhood until it begins to impart morals in the courtroom drama, following with his observation that "the book has begun to cherish its own goodness" by the time the case is over.[note 2] Defending the book, Akin Ajayi writes that justice "is often complicated, but must always be founded upon the notion of equality and fairness for all." Ajayi states that the book forces readers to question issues about race, class, and society, but that it was not written to resolve them.
Who wrote that the book forces readers to question issues without resolving them?
Answer: Akin Ajayi


Question: This is not surprising, though: While the greatest number of slaves imported from Africa were sent to Brazil, totalizing roughly 3.5 million people, they lived in such miserable conditions that male African Y-DNA there is significantly rare due to the lack of resources and time involved with raising of children, so that most African descent originarily came from relations between white masters and female slaves. From the last decades of the Empire until the 1950s, the proportion of the white population increased significantly while Brazil welcomed 5.5 million immigrants between 1821 and 1932, not much behind its neighbor Argentina with 6.4 million, and it received more European immigrants in its colonial history than the United States. Between 1500 and 1760, 700.000 Europeans settled in Brazil, while 530.000 Europeans settled in the United States for the same given time. Thus, the historical construction of race in Brazilian society dealt primarily with gradations between persons of majoritarily European ancestry and little minority groups with otherwise lower quantity therefrom in recent times.
Is there an answer to this question: What conditions did the African slaves in Brazil live in?

Answer: miserable


QUES: The first high-brightness blue LED was demonstrated by Shuji Nakamura of Nichia Corporation in 1994 and was based on InGaN. In parallel, Isamu Akasaki and Hiroshi Amano in Nagoya were working on developing the important GaN nucleation on sapphire substrates and the demonstration of p-type doping of GaN. Nakamura, Akasaki and Amano were awarded the 2014 Nobel prize in physics for their work. In 1995, Alberto Barbieri at the Cardiff University Laboratory (GB) investigated the efficiency and reliability of high-brightness LEDs and demonstrated a "transparent contact" LED using indium tin oxide (ITO) on (AlGaInP/GaAs).

What did Nakamura, Akasaki, and Amano receive for their work?
What is the answer?
ANS:
2014 Nobel prize in physics
