Burj al arab hotel, another one of the worlds tallest buildings, was finished in 1999. located in dubai, it is 1053 feet high with 60 stories. if each floor is the same height, how much taller or shorter is each floor than the height of the floors in the aon center?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
