Answer 1

Respuesta: holi :3 te ayudare :D We use when as a conjunction meaning 'at that time' the clause with when is a subordinate clause (sc) and needs a main clause (mc) to complete its meaning. if the when clause comes before  the main clause, we use a comma.

We use while as subordinate conjunctions to introduce adverbial clauses of time. they mean during the time that and indicate that something is or was happening.

Ejemplos:  While John was driving home, he saw a great accident.
