Input: Article: 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.

Now answer this question: What English Heritage status does the Civic Centre possess?

Output: grade II

Input: Article: In July 2012, Ancestry.com reported on historic and DNA research by its staff that discovered that Obama is likely a descendant through his mother of John Punch, considered by some historians to be the first African slave in the Virginia colony. An indentured servant, he was "bound for life" in 1640 after trying to escape. The story of him and his descendants is that of multi-racial America since it appeared he and his sons married or had unions with white women, likely indentured servants and working-class like them. Their multi-racial children were free because they were born to free English women. Over time, Obama's line of the Bunch family (as they became known) were property owners and continued to "marry white"; they became part of white society, likely by the early to mid-18th century.

Now answer this question: Why were his children free?

Output: they were born to free English women
