TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: Which of the following is not the title of a leader: president, emperor, or Chihuahua?, Context: Under threat from the conservative forces, Governor Terrazas was deposed, and the state legislature proclaimed martial law in the state in April 1864 and established Jesús José Casavantes as the new governor. In response, José María Patoni decided to march to Chihuahua with presidential support. Meanwhile, Maximilian von Habsburg, a younger brother of the Emperor of Austria, was proclaimed Emperor Maximilian I of Mexico on April 10, 1864 with the backing of Napoleon III and a group of Mexican conservatives. Before President Benito Juárez was forced to flee, Congress granted him an emergency extension of his presidency, which would go into effect in 1865 when his term expired, and last until 1867. At the same time, the state liberals and conservatives compromised to allow the popular Ángel Trías take the governorship; by this time the French forces had taken control over the central portions of the country and were making preparations to invade the northern states.

SOLUTION: Chihuahua

PROBLEM: Which happened earlier, the trio began playing together or the Cubs won the pennant four times between 1906 and 1910?, Context: "Baseball's Sad Lexicon," also known as "Tinker to Evers to Chance" after its refrain, is a 1910 baseball poem by Franklin Pierce Adams. The poem is presented as a single, rueful stanza from the point of view of a New York Giants fan seeing the talented Chicago Cubs infield of shortstop Joe Tinker, second baseman Johnny Evers, and first baseman Frank Chance complete a double play. The trio began playing together with the Cubs in 1902, and formed a double play combination that lasted through April 1912. The Cubs won the pennant four times between 1906 and 1910, often defeating the Giants en route to the World Series.

SOLUTION: The trio began playing together

PROBLEM: what nation is mentioned last?, Context: Eisenhower's main goals in office were to keep pressure on the Soviet Union and reduce federal deficits. In the first year of his presidency, he threatened the use of nuclear weapons in an effort to conclude the Korean War; his New Look policy of nuclear deterrence prioritized inexpensive nuclear weapons while reducing funding for conventional military forces. He ordered coups in Iran and Guatemala. Eisenhower refused to give major aid to help France in Vietnam. He gave strong financial support to the new nation of South Vietnam. Congress agreed to his request in 1955 for the Formosa Resolution, which obliged the U.S. to militarily support the pro-Western Republic of China in Taiwan and continue the isolation of the People's Republic of China.

SOLUTION:
People's Republic of China
