QUES: There are many non-incandescent light sources, such as the fluorescent lamp, high-intensity discharge lamps and LED lamps, which have higher luminous efficiency, and some have been designed to be retrofitted in fixtures for incandescent lights. These devices produce light by luminescence. These lamps produce discrete spectral lines and do not have the broad "tail" of invisible infrared emissions. By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution, the spectrum emitted can be tuned to mimic the appearance of incandescent sources, or other different color temperatures of white light. Due to the discrete spectral lines rather than a continuous spectrum, the light is not ideal for applications such as photography and cinematography.
Do fluorescent lights have a higher or lower luminous efficiency than incandescents?

ANS: higher

QUES: The city's airport was Plymouth City Airport about 4 miles (6 km) north of the city centre. The airport was home to the local airline Air Southwest, which operated flights across the United Kingdom and Ireland. In June 2003, a report by the South West RDA was published looking at the future of aviation in the south-west and the possible closure of airports. It concluded that the best option for the south-west was to close Plymouth City Airport and expand Exeter International Airport and Newquay Cornwall Airport, although it did conclude that this was not the best option for Plymouth. In April 2011, it was announced that the airport would close, which it did on 23 December. However, FlyPlymouth plans to reopen the city airport by 2018, which will provide daily services to various destinations including London.
By what year is the city airport planned to reopen?

ANS: 2018

QUES: Another group of residences, known as the Village, is located in the northwest corner of Danforth Campus. Only open to upperclassmen and January Scholars, the North Side consists of Millbrook Apartments, The Village, Village East on-campus apartments, and all fraternity houses except the Zeta Beta Tau house, which is off campus and located just northwest of the South 40. Sororities at Washington University do not have houses by their own accord. The Village is a group of residences where students who have similar interests or academic goals apply as small groups of 4 to 24, known as BLOCs, to live together in clustered suites along with non-BLOCs. Like the South 40, the residences around the Village also surround a recreational lawn.
How many January Scholars are there typically at Washington University?

ANS: unanswerable

QUES: In 2010, a number of workers committed suicide at a Foxconn operations in China. Apple, HP, and others stated that they were investigating the situation. Foxconn guards have been videotaped beating employees. Another employee killed himself in 2009 when an Apple prototype went missing, and claimed in messages to friends, that he had been beaten and interrogated.
In what year did Chinese Foxconn emplyees kill themselves?

ANS:
2010
