Input: Infection
The top three single agent/disease killers are HIV/AIDS, TB and malaria. While the number of deaths due to nearly every disease have decreased, deaths due to HIV/AIDS have increased fourfold. Childhood diseases include pertussis, poliomyelitis, diphtheria, measles and tetanus. Children also make up a large percentage of lower respiratory and diarrheal deaths. In 2012, approximately 3.1 million people have died due to lower respiratory infections, making it the number 4 leading cause of death in the world.

How much have deaths due to HIV/AIDS increased?
Output: fourfold

Input: The Blitz
The most important existing communal shelters were the London Underground stations. Although many civilians had used them as such during the First World War, the government in 1939 refused to allow the stations to be used as shelters so as not to interfere with commuter and troop travel, and the fears that occupants might refuse to leave. Underground officials were ordered to lock station entrances during raids; but by the second week of heavy bombing the government relented and ordered the stations to be opened. Each day orderly lines of people queued until 4 pm, when they were allowed to enter the stations. In mid-September 1940 about 150,000 a night slept in the Underground, although by the winter and spring months the numbers had declined to 100,000 or less. Noises of battle were muffled and sleep was easier in the deepest stations, but many were killed from direct hits on several stations.

Why were many killed in Underground Stations?
Output: direct hits

Input: Steven Spielberg
In 1985, Spielberg released The Color Purple, an adaptation of Alice Walker's Pulitzer Prize-winning novel of the same name, about a generation of empowered African-American women during depression-era America. Starring Whoopi Goldberg and future talk-show superstar Oprah Winfrey, the film was a box office smash and critics hailed Spielberg's successful foray into the dramatic genre. Roger Ebert proclaimed it the best film of the year and later entered it into his Great Films archive. The film received eleven Academy Award nominations, including two for Goldberg and Winfrey. However, much to the surprise of many, Spielberg did not get a Best Director nomination.

What did Ebert think of 'The Color Purple'?
Output: proclaimed it the best film of the year and later entered it into his Great Films archive

Input: Antenna (radio)
According to reciprocity, the efficiency of an antenna used as a receiving antenna is identical to the efficiency as defined above. The power that an antenna will deliver to a receiver (with a proper impedance match) is reduced by the same amount. In some receiving applications, the very inefficient antennas may have little impact on performance. At low frequencies, for example, atmospheric or man-made noise can mask antenna inefficiency. For example, CCIR Rep. 258-3 indicates man-made noise in a residential setting at 40 MHz is about 28 dB above the thermal noise floor. Consequently, an antenna with a 20 dB loss (due to inefficiency) would have little impact on system noise performance. The loss within the antenna will affect the intended signal and the noise/interference identically, leading to no reduction in signal to noise ratio (SNR).

What is the median level for measuring atmospheric noise?
Output:
thermal noise floor
