Problem: In response to Madero's letter to action, Pascual Orozco (a wealthy mining baron) and Chihuahua Governor Abraham González formed a powerful military union in the north, taking military control of several northern Mexican cities with other revolutionary leaders, including Pancho Villa. Against Madero's wishes, Orozco and Villa fought for and won Ciudad Juárez. After militias loyal to Madero defeated the Mexican federal army, on May 21, 1911, Madero signed the Treaty of Ciudad Juárez with Díaz. It required that Díaz abdicate his rule and be replaced by Madero. Insisting on a new election, Madero won overwhelmingly in late 1911, and he established a liberal democracy and received support from the United States and popular leaders such as Orozco and Villa. Orozco eventually became disappointed with the Madero's government and led a rebellion against him. He organized his own army, called "Orozquistas"—also called the Colorados ("Red Flaggers")—after Madero refused to agree to social reforms calling for better working hours, pay and conditions. The rural working class, which had supported Madero, now took up arms against him in support of Orozco.
Orozco and Villa fought for and won which city?
The answer is the following: Ciudad Juárez

Problem: In cities other than Rome, the name cardinal began to be applied to certain church men as a mark of honour. The earliest example of this occurs in a letter sent by Pope Zacharias in 747 to Pippin III (the Short), ruler of the Franks, in which Zacharias applied the title to the priests of Paris to distinguish them from country clergy. This meaning of the word spread rapidly, and from the 9th century various episcopal cities had a special class among the clergy known as cardinals. The use of the title was reserved for the cardinals of Rome in 1567 by Pius V.
In what year was the letter sent?
The answer is the following: 747

Problem: From 1842 onwards, Chopin showed signs of serious illness. After a solo recital in Paris on 21 February 1842, he wrote to Grzymała: "I have to lie in bed all day long, my mouth and tonsils are aching so much." He was forced by illness to decline a written invitation from Alkan to participate in a repeat performance of the Beethoven Seventh Symphony arrangement at Erard's on 1 March 1843. Late in 1844, Charles Hallé visited Chopin and found him "hardly able to move, bent like a half-opened penknife and evidently in great pain", although his spirits returned when he started to play the piano for his visitor. Chopin's health continued to deteriorate, particularly from this time onwards. Modern research suggests that apart from any other illnesses, he may also have suffered from temporal lobe epilepsy.
In which year did Chopin begin experiencing a serious decline in health?
The answer is the following: 1842
