question:
Passage: The redevelopment of the city was planned by Sir Patrick Abercrombie in his 1943 Plan for Plymouth whilst simultaneously working on the reconstruction plan for London. Between 1951 and 1957 over 1000 homes were completed every year mostly using innovative prefabricated systems of just three main types; by 1964 over 20,000 new homes had been built transforming the dense overcrowded and unsanitary slums of the pre-war city into a low density, dispersed suburbia. Most of the city centre shops had been destroyed and those that remained were cleared to enable a zoned reconstruction according to his plan. In 1962 the modernist high rise of the Civic Centre was constructed, an architecturally significant example of mid twentieth century civic slab-and-tower set piece allowed to fall into disrepair by its owner Plymouth City Council but recently grade II listed by English Heritage to prevent its demolition. Question: In the period 1951-1957, how many new houses were constructed yearly in Plymouth?
answer:
over 1000


question:
Passage: In September 1993, Madonna embarked on The Girlie Show World Tour, in which she dressed as a whip-cracking dominatrix surrounded by topless dancers. In Puerto Rico she rubbed the island's flag between her legs on stage, resulting in outrage among the audience. In March 1994, she appeared as a guest on the Late Show with David Letterman, using profanity that required censorship on television, and handing Letterman a pair of her panties and asking him to smell it. The releases of her sexually explicit films, albums and book, and the aggressive appearance on Letterman all made critics question Madonna as a sexual renegade. Critics and fans reacted negatively, who commented that "she had gone too far" and that her career was over. Question: What was Madonna dressed in for the tour?
answer:
whip-cracking dominatrix


question:
Passage: Although official German air doctrine did target civilian morale, it did not espouse the attacking of civilians directly. It hoped to destroy morale by destroying the enemy's factories and public utilities as well as its food stocks (by attacking shipping). Nevertheless, its official opposition to attacks on civilians became an increasingly moot point when large-scale raids were conducted in November and December 1940. Although not encouraged by official policy, the use of mines and incendiaries, for tactical expediency, came close to indiscriminate bombing. Locating targets in skies obscured by industrial haze meant they needed to be illuminated "without regard for the civilian population". Question: What was the primary goal of the German air doctrine?
answer:

target civilian morale
