What about this:

Which of the following is an advantage of using parallax rather than the Doppler effect to determine star distance?

		
The Doppler effect can be used only for sounds in space.
		
Parallax is more accurate for stars that are very far away.
		
Doppler shift indicates only a change in location, not actual distance.
		
Parallax is easier to use than Doppler shift.
