[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 Q]: Passage: The administration of Lord North (1770–1782) tried to defeat the colonist rebellion by military force. British and American forces clashed in 1775 and, in 1776, came the American Declaration of Independence. Burke was appalled by celebrations in Britain of the defeat of the Americans at New York and Pennsylvania. He claimed the English national character was being changed by this authoritarianism. Burke wrote: "As to the good people of England, they seem to partake every day more and more of the Character of that administration which they have been induced to tolerate. I am satisfied, that within a few years there has been a great Change in the National Character. We seem no longer that eager, inquisitive, jealous, fiery people, which we have been formerly".
[EX A]:
When was Lord North born?
