Passage: Contract law covers obligations established by agreement (express or implied) between private parties. Generally, contract law in transactions involving the sale of goods has become highly standardized nationwide as a result of the widespread adoption of the Uniform Commercial Code. However, there is still significant diversity in the interpretation of other kinds of contracts, depending upon the extent to which a given state has codified its common law of contracts or adopted portions of the Restatement (Second) of Contracts.
answer:
What does contract law not cover?


question:
Passage: Numerous plays are put on every year at Eton College; there is one main theatre, called the Farrer (seating 400) and 2 Studio theatres, called the Caccia Studio and Empty Space (seating 90 and 80 respectively). There are about 8 or 9 house productions each year, around 3 or 4 "independent" plays (not confined solely to one house, produced, directed and funded by Etonians) and three school plays, one specifically for boys in the first two years, and two open to all years. The School Plays have such good reputations that they are normally fully booked every night. Productions also take place in varying locations around the School, varying from the sports fields to more historic buildings such as Upper School and College Chapel.
answer:
How many people can sit in College Chapel?


question:
Passage: In 1939, coinciding with the start of World War II, Rene Dubos reported the discovery of the first naturally derived antibiotic, tyrothricin, a compound of 20% gramicidin and 80% tyrocidine, from B. brevis. It was one of the first commercially manufactured antibiotics universally and was very effective in treating wounds and ulcers during World War II. Gramicidin, however, could not be used systemically because of toxicity. Tyrocidine also proved too toxic for systemic usage. Research results obtained during that period were not shared between the Axis and the Allied powers during the war.
answer:

What was the first antibiotic developed from wounds?
