In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
Which of the following is NOT a goal of phorphor LED development: higher light output, optical losses, or higher operation temperatures?, Context: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.

Ex Output:
optical losses

Ex Input:
how many seats does the theatre located on First Hill have?, Context: The 5th Avenue Theatre, built in 1926, stages Broadway-style musical shows featuring both local talent and international stars. Seattle has "around 100" theatrical production companies and over two dozen live theatre venues, many of them associated with fringe theatre; Seattle is probably second only to New York for number of equity theaters (28 Seattle theater companies have some sort of Actors' Equity contract). In addition, the 900-seat Romanesque Revival Town Hall on First Hill hosts numerous cultural events, especially lectures and recitals.

Ex Output:
900

Ex Input:
What sport do the Hurricanes play?, Context: The National Hockey League's Carolina Hurricanes franchise moved to Raleigh in 1997 from Hartford, Connecticut (where it was known as the Hartford Whalers). The team played its first two seasons more than 60 miles away at Greensboro Coliseum while its home arena, Raleigh Entertainment and Sports Arena (later RBC Center and now PNC Arena), was under construction. The Hurricanes are the only major league (NFL, NHL, NBA, MLB) professional sports team in North Carolina to have won a championship, winning the Stanley Cup in 2006, over the Edmonton Oilers. The city played host to the 2011 NHL All-Star Game.

Ex Output:
Hockey
