question:
Doctor is an academic title that originates from the Latin word of the same spelling and meaning. The word is originally an agentive noun of the Latin verb docēre (dɔˈkeːrɛ) 'to teach'. It has been used as an academic title in Europe since the 13th century, when the first doctorates were awarded at the University of Bologna and the University of Paris. Having become established in European universities, this usage spread around the world. Contracted ``Dr'' or ``Dr.'', it is used as a designation for a person who has obtained a Doctorate (e.g. PhD). In many parts of the world it is also used by medical practitioners, regardless of whether or not they hold a doctoral-level degree.

question:
The Empire State Building stood as the tallest building in the world from its completion until 1972, when the 110-story North Tower of the original World Trade Center was completed. At 1,368 feet (417 m), The World Trade Center briefly held the title as the world's tallest building until the completion of the 108-story Willis Tower (formerly known as the Sears Tower) in Chicago in 1974. The World Trade Center towers were destroyed by terrorist attacks in 2001, and the Empire State Building regained the title of tallest building in the City. It remained the tallest until April 2012, when the construction on One World Trade Center surpassed it. The fourth-tallest building in New York is the Bank of America Tower, which rises to 1,200 feet (366 m), including its spire. Tied for fifth-tallest are the 1,046-foot (319 m) Chrysler Building, which was the world's tallest building from 1930 until 1931, and the New York Times Building, which was completed in 2007. If the Twin Towers were still standing today, they would be the third and fourth tallest buildings in the city, or second and third assuming the new buildings would not have been built. Only 432 Park Avenue is taller.
answer:

are the twin towers taller than empire state building?
