Problem: The poor performance of the Portuguese economy was explored in April 2007 by The Economist, which described Portugal as "a new sick man of Europe". From 2002 to 2007, the number of unemployed increased by 65% (270,500 unemployed citizens in 2002, 448,600 unemployed citizens in 2007). By early December 2009, the unemployment rate had reached 10.2% a 23-year record high. In December 2009, ratings agency Standard & Poor's lowered its long-term credit assessment of Portugal to "negative" from "stable," voicing pessimism on the country's structural weaknesses in the economy and weak competitiveness that would hamper growth and the capacity to strengthen its public finances and reduce debt. In July 2011, ratings agency Moody's downgraded its long-term credit assessment of Portugal after warning of deteriorating risk of default in March 2011.
In 2009, what rating did Standard & Poor's assign to Portugal's long-term credit assessment?
The answer is the following: negative

As an academic field, history of science began with the publication of William Whewell's History of the Inductive Sciences (first published in 1837). A more formal study of the history of science as an independent discipline was launched by George Sarton's publications, Introduction to the History of Science (1927) and the Isis journal (founded in 1912). Sarton exemplified the early 20th-century view of the history of science as the history of great men and great ideas. He shared with many of his contemporaries a Whiggish belief in history as a record of the advances and delays in the march of progress. The history of science was not a recognized subfield of American history in this period, and most of the work was carried out by interested scientists and physicians rather than professional historians. With the work of I. Bernard Cohen at Harvard, the history of science became an established subdiscipline of history after 1945.
What text is the foundation of the study of the history of science?
History of the Inductive Sciences

Input: Article: Immediately after the War The Saint-Germain-des-Pres quarter and the nearby Saint-Michel quarter became home to many small jazz clubs, mostly found in cellars because of a lack of space; these included the Caveau des Lorientais, the Club Saint-Germain, the Rose Rouge, the Vieux-Colombier, and the most famous, Le Tabou.
