This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

[EX Q]: In September 2003, a new type of blue LED was demonstrated by Cree that consumes 24 mW at 20 milliamperes (mA). This produced a commercially packaged white light giving 65 lm/W at 20 mA, becoming the brightest white LED commercially available at the time, and more than four times as efficient as standard incandescents. In 2006, they demonstrated a prototype with a record white LED luminous efficacy of 131 lm/W at 20 mA. Nichia Corporation has developed a white LED with luminous efficacy of 150 lm/W at a forward current of 20 mA. Cree's XLamp XM-L LEDs, commercially available in 2011, produce 100 lm/W at their full power of 10 W, and up to 160 lm/W at around 2 W input power. In 2012, Cree announced a white LED giving 254 lm/W, and 303 lm/W in March 2014. Practical general lighting needs high-power LEDs, of one watt or more. Typical operating currents for such devices begin at 350 mA.
[EX A]: In what year was a new type of blue LED produced?

[EX Q]: He attained a perfect score on the graduate school entrance exams to Princeton University in mathematics and physicsan unprecedented featbut did rather poorly on the history and English portions. Attendees at Feynman's first seminar included Albert Einstein, Wolfgang Pauli, and John von Neumann. He received a PhD from Princeton in 1942; his thesis advisor was John Archibald Wheeler. Feynman's thesis applied the principle of stationary action to problems of quantum mechanics, inspired by a desire to quantize the WheelerFeynman absorber theory of electrodynamics, laying the groundwork for the "path integral" approach and Feynman diagrams, and was titled "The Principle of Least Action in Quantum Mechanics".
[EX A]: Which two sections of the graduate exam did Feynman excel in?

[EX Q]: One of the league's early success stories was the Detroit Drive. A primary team for some of the AFL's most highly regarded players, including George LaFrance and Gary and Alvin Rettig, as well as being a second career chance for quarterback Art Schlichter, the Drive regularly played before sold out crowds at Joe Louis Arena, and went to the ArenaBowl every year of their existence (19881993). The AFL's first dynasty came to an end when their owner, Mike Ilitch (who also owned Little Caesars Pizza and the Detroit Red Wings) bought the Detroit Tigers baseball team and sold the AFL team.

What team did Art Schlichter play for?
