Input: Article: Three Han mathematical treatises still exist. These are the Book on Numbers and Computation, the Arithmetical Classic of the Gnomon and the Circular Paths of Heaven and the Nine Chapters on the Mathematical Art. Han-era mathematical achievements include solving problems with right-angle triangles, square roots, cube roots, and matrix methods, finding more accurate approximations for pi, providing mathematical proof of the Pythagorean theorem, use of the decimal fraction, Gaussian elimination to solve linear equations, and continued fractions to find the roots of equations.

Now answer this question: How many mathematical treatises have still managed to survive to this day?

Output: Three

Input: Article: The Germans launched a surprise counter offensive, in the Battle of the Bulge in December 1944, which the Allies turned back in early 1945 after Eisenhower repositioned his armies and improved weather allowed the Air Force to engage. German defenses continued to deteriorate on both the eastern front with the Soviets and the western front with the Allies. The British wanted Berlin, but Eisenhower decided it would be a military mistake for him to attack Berlin, and said orders to that effect would have to be explicit. The British backed down, but then wanted Eisenhower to move into Czechoslovakia for political reasons. Washington refused to support Churchill's plan to use Eisenhower's army for political maneuvers against Moscow. The actual division of Germany followed the lines that Roosevelt, Churchill and Stalin had previously agreed upon. The Soviet Red Army captured Berlin in a very large-scale bloody battle, and the Germans finally surrendered on May 7, 1945.

Now answer this question: Along with Roosevelt and Churchill, what political leader decided upon the division of Germany?

Output: Stalin

Input: Article: 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 Barça'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.

Now answer this question: How was Espanyol viewed as being toward Spanish authority by the people of Barcelona?

Output:
compliance
