range

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for range that I've seen before include "Old-style cooking stove" , "A set of different things of the same general type" , "Old song: ''Home on the . . . . .''" , "sight" , "on which 'Dr Brewster Higley' felt at home?" .)

I've seen this clue in The Sun.
