Input: London
London was the world's largest city from about 1831 to 1925. London's overcrowded conditions led to cholera epidemics, claiming 14,000 lives in 1848, and 6,000 in 1866. Rising traffic congestion led to the creation of the world's first local urban rail network. The Metropolitan Board of Works oversaw infrastructure expansion in the capital and some of the surrounding counties; it was abolished in 1889 when the London County Council was created out of those areas of the counties surrounding the capital. London was bombed by the Germans during the First World War while during the Second World War, the Blitz and other bombings by the German Luftwaffe, killed over 30,000 Londoners and destroyed large tracts of housing and other buildings across the city. Immediately after the war, the 1948 Summer Olympics were held at the original Wembley Stadium, at a time when London had barely recovered from the war.

Who bombed London in both World War I and World War II?
Output: the Germans

Input: Alexander Graham Bell
Intrigued by the results of the automaton, Bell continued to experiment with a live subject, the family's Skye Terrier, "Trouve". After he taught it to growl continuously, Bell would reach into its mouth and manipulate the dog's lips and vocal cords to produce a crude-sounding "Ow ah oo ga ma ma". With little convincing, visitors believed his dog could articulate "How are you grandma?" More indicative of his playful nature, his experiments convinced onlookers that they saw a "talking dog". However, these initial forays into experimentation with sound led Bell to undertake his first serious work on the transmission of sound, using tuning forks to explore resonance.

What did Bell  instruct his dog to do?
Output: growl continuously
