Example Input: From 7 September 1940, one year into the war, London was bombed by the Luftwaffe for 57 consecutive nights. More than one million London houses were destroyed or damaged and more than 40,000 civilians were killed, almost half of them in London. Ports and industrial centres outside London were also attacked. The main Atlantic sea port of Liverpool was bombed, causing nearly 4,000 deaths within the Merseyside area during the war. The North Sea port of Hull, a convenient and easily found target or secondary target for bombers unable to locate their primary targets, was subjected to 86 raids in the Hull Blitz during the war, with a conservative estimate of 1,200 civilians killed and 95 percent of its housing stock destroyed or damaged. Other ports including Bristol, Cardiff, Portsmouth, Plymouth, Southampton and Swansea were also bombed, as were the industrial cities of Birmingham, Belfast, Coventry, Glasgow, Manchester and Sheffield. Birmingham and Coventry were chosen because of the Spitfire and tank factories in Birmingham and the many munitions factories in Coventry. The city centre of Coventry was almost destroyed, as was Coventry Cathedral.
Example Output: How many nights did the Luftwaffe bomb London?

Example Input: For his second album, Late Registration (2005), he collaborated with film score composer Jon Brion and drew influence from non-rap influences such as English trip hop group Portishead. Blending West's primary soulful hip hop production with Brion's elaborate chamber pop orchestration, the album experimentally incorporated a wide array of different genres and prominent orchestral elements, including string arrangements, piano chords, brass flecks, and horn riffs among other symphonic instrumentation. It also incorporated a myriad of foreign and vintage instruments not typical in popular music, let alone hip hop, such as a celesta, harpsichord, Chamberlin, CS-80 analog synthesizer, Chinese bells and berimbau, vibraphones, and marimba. Rolling Stone described Late Registration as West claiming "the whole world of music as hip-hop turf" chronicling the album as "his mad quest to explode every cliche about hip-hop identity." Critic Robert Christgau wrote that "there's never been hip-hop so complex and subtle musically." For a period of time, Kanye West stood as the sole current pop star to tour with a string section, as audible on his 2006 live album Late Orchestration.
Example Output: What composer did Kanye collaborate with for his second record?

Example Input: It is common to classify wood as either softwood or hardwood. The wood from conifers (e.g. pine) is called softwood, and the wood from dicotyledons (usually broad-leaved trees, e.g. oak) is called hardwood. These names are a bit misleading, as hardwoods are not necessarily hard, and softwoods are not necessarily soft. The well-known balsa (a hardwood) is actually softer than any commercial softwood. Conversely, some softwoods (e.g. yew) are harder than many hardwoods.
Example Output:
What term do we use for the wood that comes from pine trees?
