This is from Brutal SC document -

A. so as to warm up the rooms
B. and so would be able to warm up the rooms
C. to warm the rooms up
D. so that they could warm up the rooms
E. in order that they would warm up the rooms
OA is given as D.
Instructors, I am giving my exam in a week. Can you please explain when to use so that/so as to/ to. I am always confused.
I picked A because I have seen GMAC use 'so as to' in other questions.
Also, which is correct - warm up the rooms or warm the rooms up?
this question is horrible. you should run away from this source as fast as you can. don't look back.
you could argue for any one of (a), (c), or (d) here. all are acceptable.
if this were an official problem, it would say something like "in order to warm the rooms".
