[EX Q]: Passage: There is no natural source for green food colorings which has been approved by the US Food and Drug Administration. Chlorophyll, the E numbers E140 and E141, is the most common green chemical found in nature, and only allowed in certain medicines and cosmetic materials. Quinoline Yellow (E104) is a commonly used coloring in the United Kingdom but is banned in Australia, Japan, Norway and the United States. Green S (E142) is prohibited in many countries, for it is known to cause hyperactivity, asthma, urticaria, and insomnia.
[EX A]: Which two E numbers have been approved by the FDA?

[EX Q]: Passage: The northern side of Miami includes Midtown, a district with a great mix of diversity with many West Indians, Hispanics, European Americans, bohemians, and artists. Edgewater, and Wynwood, are neighborhoods of Midtown and are made up mostly of high-rise residential towers and are home to the Adrienne Arsht Center for the Performing Arts. The wealthier residents usually live in the northeastern part, in Midtown, the Design District, and the Upper East Side, with many sought after 1920s homes and home of the MiMo Historic District, a style of architecture originated in Miami in the 1950s. The northern side of Miami also has notable African American and Caribbean immigrant communities such as Little Haiti, Overtown (home of the Lyric Theater), and Liberty City.
[EX A]: What unnotable theater is present in Overtown?

[EX Q]: Passage: A local pioneer of folk song collection in the first half of the 19th century was Shakespearean scholar James Orchard Halliwell, but it was not until the second folk revival in the 20th century that the full range of song from the county, including industrial folk song, began to gain attention. The county produced one of the major figures of the revival in Ewan MacColl, but also a local champion in Harry Boardman, who from 1965 onwards probably did more than anyone to popularise and record the folk song of the county. Perhaps the most influential folk artists to emerge from the region in the late 20th century were Liverpool folk group The Spinners, and from Manchester folk troubadour Roy Harper and musician, comedian and broadcaster Mike Harding. The region is home to numerous folk clubs, many of them catering to Irish and Scottish folk music. Regular folk festivals include the Fylde Folk Festival at Fleetwood.
[EX A]:
In what year was James Orchard Halliwell born?
