According to MGMAT SC
, "subordinators, such as because and although, create subordinate clauses, which can in turn attach to a main clause WITH A COMMA".
I need to relax,
BECAUSE I have so many things to do.
Does always a subordinator have to go with a comma in a sentence?
I remember that when I learned English that it is not necessarily true.
Please, base your answer on the GMAT rules, not in your daily English knowledge.
