Favorite Answer

No comma before dependent adverb clauses. This includes clauses starting with because, although, when, before, after, etc. 

Answer 2

The children were running in the aisles of the supermarket until one of them crashed into a shopper.

Answer 3

While "The children were running in the aisles of the supermarket, before one of them crashed into a shopper." is almost grammatically correct, it would be more proper to say: "One of the children crashed into a shopper after they were running in the supermarket's aisles."

Answer 4

i would say then rather than before but that is just personal preference

Answer 5

It's unclear whether the children were running until the crash and had to stop, or if the crash was just one result of the running.

Answer 6

Yes it's fine but the comma is not necessary
