question:
Passage: After the Nazis came to power, he emigrated to Switzerland in 1933 and to the United States later. He began his studies in Zurich and worked part-time as a house teacher. Meanwhile, he wrote articles and book reviews for the Neue Zürcher Zeitung, using several pseudonyms because of prohibition of work. He earned his PhD and taught French and German Literature at various universities, including Princeton University and University of Wisconsin-Madison. During a journey to Europe, Vordtriede was surprised by the outbreak of the Second World War and interned as an Enemy alien in occupied France. By interventions, he became free months later and was allowed to go back to America. He met his mother in New York City late in 1941, who also emigrated to the USA. He received the American citizenship in 1946 and became a Guggenheim Fellow in 1957. His sister Fränze emigrated in 1947 and went to Philadelphia.

question:
Passage: The 19th annual Arab League summit reaffirmed the Arab Peace Initiative first adopted in 2002 (also known as the Beirut Declaration). Arab leaders at the summit urged Israel to accept this initiative. Saudi Foreign Minister Prince Saud al-Faisal said that the plan would have a strong chance of winning international support and of reviving Israeli–Arab peace talks if adopted unanimously by all Arab leaders. The plan, moreover, set up a mechanism to promote the peace plan that would pave the way for Arab countries with no ties to Israel, including Saudi Arabia, to open channels of communications with the Jewish state—a longtime goal for various presidential administrations in the United States. The peace initiative, as Middle Eastern scholars explain, was considered a "great leap from historical resolutions of 1964 and 1967, which had vowed to destroy Israel." Under the plan, Arab nations would recognize Israel if Israel withdrew from land it occupied in the 1967 Arab-Israeli war. Moreover, the plan allows for the creation of a Palestinian state—with its capital in East Jerusalem—and the return of Palestinian refugees based on United Nations General Assembly Resolution 194. The final draft of the plan, moreover, avoided mentioning the phrase "right of return", which has been a point of contention in all previous peace talks; instead it called for a "just solution to the Palestinian refugee problem."

question:
Passage: "Tobacco", an eighteen-minute segment about the tobacco industry, was delivered by John Oliver on February 15, 2015, during the second episode of Last Week Tonight second season. Oliver introduces the topic of tobacco smoking by showing video clips of "trusted newsmen, cartoon characters, and cowboys in TV commercials" who are smoking cigarettes. He says that the cowboy in the clip is Marlboro Man, a figure used in advertising campaigns for Marlboro cigarettes, and notes that four of the actors portraying Marlboro Man have died from lung cancer or smoking-related illnesses. Oliver says that cigarette smoking is no longer as prevalent in the United States because of, among other things, mandatory warnings on all cigarette boxes and a ban on TV advertisements for cigarettes. The comedian says that tobacco executives adamantly refused to acknowledge the potential drawbacks to smoking, despite strong evidence to prove these drawbacks. He shows a video of Joseph Cullman, the former CEO of the tobacco company Philip Morris International (PMI), saying that "some women would prefer having smaller babies" in response to a reporter's comment that pregnant women who smoke will give birth to smaller babies as a result. Even so, the restrictions on smoking advertisements contributed to a decline in smoking rates among American adults, as only 18% of adults smoked in 2014, compared to 43% of adults in 1965.
