Traditionally, Espanyol was seen by the vast majority of Barcelona's citizens as a club which cultivated a kind of compliance to the central authority, in stark contrast to Barca's revolutionary spirit. Also in the 1960s and 1970s, while FC Barcelona acted as an integrating force for Catalonia's new arrivals from poorer regions of Spain expecting to find a better life, Espanyol drew their support mainly from sectors close to the regime such as policemen, military officers, civil servants and career fascists.
From where did Espanyol draw their supporters?
****
The answer: close to the regime

In February 1939, he received news from his sisters that his mother was dying. On 10 February 1939, Pope Pius XI died. Roncalli was unable to see his mother for the end as the death of a pontiff meant that he would have to stay at his post until the election of a new pontiff. Unfortunately, she died on 20 February 1939, during the nine days of mourning for the late Pius XI. He was sent a letter by Cardinal Eugenio Pacelli, and Roncalli later recalled that it was probably the last letter Pacelli sent until his election as Pope Pius XII on 2 March 1939. Roncalli expressed happiness that Pacelli was elected, and, on radio, listened to the coronation of the new pontiff.
When did Pope Pius XI die?
****
The answer: 10 February 1939

Samuel of IBM's Poughkeepsie, New York, laboratory programmed an IBM 704 not merely to play checkers but "learn" from its own experience. In 1957, the FORTRAN (FORmula TRANslation) scientific programming language was developed. In 1961, Thomas J. Watson, Jr., was elected chairman of the board and Albert L.

The problem: Answer a question about this article:
Whether there are measurable changes in the sea level relative to the islands of Tuvalu is a contentious issue. There were problems associated with the pre-1993 sea level records from Funafuti which resulted in improvements in the recording technology to provide more reliable data for analysis. The degree of uncertainty as to estimates of sea level change relative to the islands of Tuvalu was reflected in the conclusions made in 2002 from the available data. The 2011 report of the Pacific Climate Change Science Program published by the Australian Government, concludes: "The sea-level rise near Tuvalu measured by satellite altimeters since 1993 is about 5 mm (0.2 in) per year."
What is assumed about the sea level reports and records of Tuvalu?
****
The answer:
degree of uncertainty
