You will be shown 10 random numbers between 1 and 100 without knowing what's next. Your task is to put them in order! But beware, if a number cannot be placed, the quiz ends...
Baltimore only has one international airport- BWI- that also serves Washington. Washington has two other international airports (National and Dulles). Maybe you meant Washington instead of Baltimore?
What are the other two? If you mean DCA and IAD then I agree that Washington should be the answer given it is in the name of all three, while BWI is the only one to carry Baltimore in its name.
