(a) They raised the flag at a steady rate the whole time.
(b) They raised it quickly at first then as it got higher they slowed down.
(c) They raised it then lowered it a little then raised it then lowered it a little over and over. Maybe the flag falls down a tiny bit after each time they raise it.
(d) They raised it slowly at first, then faster.
(e) They raised it slowly, then really fast, then slow again.
(f) They raised the entire thing in 0 seconds, in one instant. Also that means the flag was at all of the different heights at the same time.
The most realistic one might be c , or it could be e ...?
