Input: Article: The Scheinergrade (Sch.) system was devised by the German astronomer Julius Scheiner (18581913) in 1894 originally as a method of comparing the speeds of plates used for astronomical photography. Scheiner's system rated the speed of a plate by the least exposure to produce a visible darkening upon development. Speed was expressed in degrees Scheiner, originally ranging from 1 Sch. to 20 Sch., where an increment of 19 Sch. corresponded to a hundredfold increase in sensitivity, which meant that an increment of 3 Sch. came close to a doubling of sensitivity.

Now answer this question: What is the range of Scheiner speeds?

Output: from 1 Sch. to 20 Sch

Input: Article: In 1922, the number of supporters had surpassed 20,000 and by lending money to the club, Barca was able to build the larger Camp de Les Corts, which had an initial capacity of 20,000 spectators. After the Spanish Civil War the club started attracting more members and a larger number of spectators at matches. This led to several expansion projects: the grandstand in 1944, the southern stand in 1946, and finally the northern stand in 1950. After the last expansion, Les Corts could hold 60,000 spectators.

Input: Article: Because of his stammer, Albert dreaded public speaking. After his closing speech at the British Empire Exhibition at Wembley on 31 October 1925, one which was an ordeal for both him and his listeners, he began to see Lionel Logue, an Australian-born speech therapist. The Duke and Logue practised breathing exercises, and the Duchess rehearsed with him patiently. Subsequently, he was able to speak with less hesitation. With his delivery improved, the Duke opened the new Parliament House in Canberra, Australia, during a tour of the empire in 1927. His journey by sea to Australia, New Zealand and Fiji took him via Jamaica, where Albert played doubles tennis partnered with a black man, which was unusual at the time and taken locally as a display of equality between races.

Now answer this question: Why did Albert fear speaking in public?

Output:
his stammer
