Article: In 1938 Otto Hahn and Fritz Strassmann discovered nuclear fission with radiochemical methods, and in 1939 Lise Meitner and Otto Robert Frisch wrote the first theoretical interpretation of the fission process, which was later improved by Niels Bohr and John A. Wheeler. Further developments took place during World War II, which led to the practical application of radar and the development and use of the atomic bomb. Though the process had begun with the invention of the cyclotron by Ernest O. Lawrence in the 1930s, physics in the postwar period entered into a phase of what historians have called "Big Science", requiring massive machines, budgets, and laboratories in order to test their theories and move into new frontiers. The primary patron of physics became state governments, who recognized that the support of "basic" research could often lead to technologies useful to both military and industrial applications. Currently, general relativity and quantum mechanics are inconsistent with each other, and efforts are underway to unify the two.

Question: What is the problem with general relativity and quantum mechanics?
Ans: inconsistent with each other


Article: After the President signs a bill into law (or Congress enacts it over his veto), it is delivered to the Office of the Federal Register (OFR) of the National Archives and Records Administration (NARA) where it is assigned a law number, and prepared for publication as a slip law. Public laws, but not private laws, are also given legal statutory citation by the OFR. At the end of each session of Congress, the slip laws are compiled into bound volumes called the United States Statutes at Large, and they are known as session laws. The Statutes at Large present a chronological arrangement of the laws in the exact order that they have been enacted.

Question: After being given a law number, a new law is prepared for publication as what?
Ans: a slip law


Article: A considerable amount of new knowledge about plant function comes from studies of the molecular genetics of model plants such as the Thale cress, Arabidopsis thaliana, a weedy species in the mustard family (Brassicaceae). The genome or hereditary information contained in the genes of this species is encoded by about 135 million base pairs of DNA, forming one of the smallest genomes among flowering plants. Arabidopsis was the first plant to have its genome sequenced, in 2000. The sequencing of some other relatively small genomes, of rice (Oryza sativa) and Brachypodium distachyon, has made them important model species for understanding the genetics, cellular and molecular biology of cereals, grasses and monocots generally.

Question: Why is sequencing done on plants?
Ans: understanding the genetics


Article: One significant feature of the Premier League in the mid-2000s was the dominance of the so-called "Big Four" clubs: Arsenal, Chelsea, Liverpool and Manchester United. During this decade, and particularly from 2002 to 2009, they dominated the top four spots, which came with UEFA Champions League qualification, taking all top four places in 5 out of 6 seasons from 2003–04 to 2008–09 inclusive, with Arsenal going as far as winning the league without losing a single game in 2003–04, the only time it has ever happened in the Premier League. In May 2008 Kevin Keegan stated that "Big Four" dominance threatened the division, "This league is in danger of becoming one of the most boring but great leagues in the world." Premier League chief executive Richard Scudamore said in defence: "There are a lot of different tussles that go on in the Premier League depending on whether you're at the top, in the middle or at the bottom that make it interesting."

Question: Which of the "Big Four" teams did not lose a single game in the 2003-04 season?
Ans:
Arsenal
