instruction:
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
question:
What is a gathering to celebrate an event?, Context: The style and role of any minority leader is influenced by a variety of elements, including personality and contextual factors, such as the size and cohesion of the minority party, whether his or her party controls the White House, the general political climate in the House, and the controversy that is sometimes associated with the legislative agenda. Despite the variability of these factors, there are a number of institutional obligations associated with this position. Many of these assignments or roles are spelled out in the House rule book. Others have devolved upon the position in other ways. To be sure, the minority leader is provided with extra staff resources—beyond those accorded him or her as a Representative—to assist in carrying out diverse leadership functions. Worth emphasis is that there are limits on the institutional role of the minority leader, because the majority party exercises disproportionate influence over the agenda, partisan ratios on committees, staff resources, administrative operations, and the day-to-day schedule and management of floor activities.
answer:
party


question:
Waves contain?, Context: As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.
answer:
power


question:
What came about three years after the Metrobus line?, Context: The city's first bus rapid transit line, the Metrobús, began operation in June 2005, along Avenida Insurgentes. Line 2 opened in December 2008, serving Eje 4 Sur, line 3 opened in February 2011, serving Eje 1 Poniente, and line 4 opened in April 2012 connecting the airport with San Lázaro and Buenavista Station at Insurgentes. As the microbuses were removed from its route, it was hoped that the Metrobús could reduce pollution and decrease transit time for passengers. In June 2013, Mexico City's mayor announced two more lines to come: Line 5 serving Eje 3 Oriente and Line 6 serving Eje 5 Norte. As of June 2013, 367 Metrobús buses transported 850,000 passengers daily.
answer:

Line 2 opened
