Somebody who had lived their first fourteen years of their life in the U.S., moved out, and have been back in the U.S. for less than fourteen years.
Probably
Somebody who was born in the U.S., moved out before their fourteenth birthday, and have been back in the U.S. for less than fourteen years, but overall has lived in the U.S. for greater than 14 years.
Yes
Since the first choice would also mean 14 combined years, if the second choice is Yes, I guess the first choice is Yes then as well. Thanks for your help
