Example Input: 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?
Example Output: over 1000

Example Input: Passage: Between 2000 and 2004 an average of 478 crimes were reported each day in Mexico City; however, the actual crime rate is thought to be much higher "since most people are reluctant to report crime". Under policies enacted by Mayor Marcelo Ebrard between 2009 and 2011, Mexico City underwent a major security upgrade with violent and petty crime rates both falling significantly despite the rise in violent crime in other parts of the country. Some of the policies enacted included the installation of 11,000 security cameras around the city and a very large expansion of the police force. Mexico City has one of the world's highest police officer-to-resident ratios, with one uniformed officer per 100 citizens. Question: What Mexican mayor tried to crack down on crime immensely? 
Example Output: Marcelo Ebrard
