Input: BeiDou Navigation Satellite System
Compass-M1 is an experimental satellite launched for signal testing and validation and for the frequency filing on 14 April 2007. The role of Compass-M1 for Compass is similar to the role of the GIOVE satellites for the Galileo system. The orbit of Compass-M1 is nearly circular, has an altitude of 21,150 km and an inclination of 55.5 degrees.

What is the inclination of the Compass-M1 satellite?
Output: 55.5 degrees

Input: Light-emitting diode
While LEDs have the advantage over fluorescent lamps that they do not contain mercury, they may contain other hazardous metals such as lead and arsenic. Regarding the toxicity of LEDs when treated as waste, a study published in 2011 stated: "According to federal standards, LEDs are not hazardous except for low-intensity red LEDs, which leached Pb [lead] at levels exceeding regulatory limits (186 mg/L; regulatory limit: 5). However, according to California regulations, excessive levels of copper (up to 3892 mg/kg; limit: 2500), lead (up to 8103 mg/kg; limit: 1000), nickel (up to 4797 mg/kg; limit: 2000), or silver (up to 721 mg/kg; limit: 500) render all except low-intensity yellow LEDs hazardous."

What substance does fluorescent lamps contain?
Output: mercury

Input: John, King of England
Letters of support from the pope arrived in April but by then the rebel barons had organised. They congregated at Northampton in May and renounced their feudal ties to John, appointing Robert fitz Walter as their military leader. This self-proclaimed "Army of God" marched on London, taking the capital as well as Lincoln and Exeter. John's efforts to appear moderate and conciliatory had been largely successful, but once the rebels held London they attracted a fresh wave of defectors from John's royalist faction. John instructed Langton to organise peace talks with the rebel barons.

Who was the rebel baron leader?
Output: Robert fitz Walter

Input: Late Middle Ages
The end of medieval drama came about due to a number of factors, including the weakening power of the Catholic Church, the Protestant Reformation and the banning of religious plays in many countries. Elizabeth I forbid all religious plays in 1558 and the great cycle plays had been silenced by the 1580s. Similarly, religious plays were banned in the Netherlands in 1539, the Papal States in 1547 and in Paris in 1548. The abandonment of these plays destroyed the international theatre that had thereto existed and forced each country to develop its own form of drama. It also allowed dramatists to turn to secular subjects and the reviving interest in Greek and Roman theatre provided them with the perfect opportunity.

In what year were religious plays banned in the Netherlands?
Output:
1539
