Input: Article: In the late eighteenth- and early nineteenth-century Germany, three pioneer physical educators – Johann Friedrich GutsMuths (1759–1839) and Friedrich Ludwig Jahn (1778–1852) – created exercises for boys and young men on apparatus they had designed that ultimately led to what is considered modern gymnastics. Don Francisco Amorós y Ondeano, was born on February 19, 1770 in Valence and died on August 8, 1848 in Paris. He was a Spanish colonel, and the first person to introduce educative gymnastic in France. Jahn promoted the use of parallel bars, rings and high bar in international competition.

Input: Article: The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.

Now answer this question: What is solar energy's yearly potential?

Output: 1,575–49,837 exajoules (EJ)

Input: Article: Due to the legitimate role that referees play in wrestling of serving as liaison between the bookers backstage and the wrestlers in the ring (the role of being a final arbitrator is merely kayfabe), the referee is present, even in matches that do not at first glance appear to require a referee (such as a ladder match, as it is no holds barred, and the criteria for victory could theoretically be assessed from afar). Although their actions are also frequently scripted for dramatic effect, referees are subject to certain general rules and requirements in order to maintain the theatrical appearance of unbiased authority. The most basic rule is that an action must be seen by a referee to be declared for a fall or disqualification. This allows for heel characters to gain a scripted advantage by distracting or disabling the referee in order to perform some ostensibly illegal maneuver on their opponent. Most referees are unnamed and essentially anonymous, though the WWE has let their officials reveal their names.

Now answer this question: What determines how the referee acts?

Output:
