This question is a little too ambiguous to be a true (official) GMAT question.
Does order matter here?
For example, is E driving, A in passenger seat, G in middle of back seat, and C in left side of back seat DIFFERENT FROM C driving, A in passenger seat, E in middle of back seat, and G in left side of back seat?


Cheers,
