Types of questions like these are kinda hard. we know for sure the 4th one is not correct bc it says that the flying oval office is more tranquil than the White House so it has nothing to do with the rooms. from the question that is being asked it says nothing about people knowing force one is used to transport the president. so we are down to answer three and one. although one does seem correct because of the first set of sentences the second set of sentences doesn't really have anything to do with a symbol of presidency. I would guess the third one because it is more broad and both sentences talk about the exterior of the plane.
