2) Mr. Darcy makes a stop at the NJ gas station. He fills 14 gallons of gasoline in his Honda Odyssey. The fuel tank is now two thirds full. What is the maximum capacity of the fuel tank?

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.
