The Sears Tower's name was changed to the Willis Tower in 2011, since Willis Corp. is its primary tenant. The John Hancock Tower is in Boston, the John Hancock Center in Chicago. The Trump Hotel is in NYC, the Trump World Hotel and Tower in Chicago. There's an Aon Center in Chicago and in Los Angeles. Since they're all correct, the quiz won't be changed. I can't change Aon center to Aon because that's the name of a company, not a building.
It doesn't matter if there is a trump tower in nyc when this quiz is about chicago. Wouldn't it be a given that the trump tower here is not the one in nyc?
This Quiz is in dire need of updating. The John Hancock - as we call it here in Chicago - should now also be known as 875 N. Michigan Ave. I agree its the Sears Tower.
