Write the subordinate conjunctions of each sentences
1-We drove home carefully,because it was snowing. sub is( because)
2-We had classes until noon although the weather was bad. sub(until, although)
3-If the snow is deep enough, there will be no school tomorrow.sub (if,enough)
4-School is closed only when the snow is deep.sub(when)
5-Where Lisa and Marco live, there are usually two deep snows every year.sub(where)
2 and 3 only have one subordinate conjunction in each.
The rest are correct.
In number 2 although is a subordinate and until because in list they include both
so which one I choose
Until is a preposition in this sentence. It begins the phrase "until noon."
