I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "The Russian R-7 rocket family, which launched the first Sputnik at the beginning of the space race, is still in use today. It services the International Space Station (ISS) as the launcher for both the Soyuz and Progress spacecraft. It also ferries both Russian and American crews to and from the station."? 

Russians and Americans live on the?
