Commander Stella is drafting an apology email to Mission Control because she overslept on the day of her space flight.
Select ALL the correctly punctuated sentences she can use to explain her tardiness.
The correct answers are:
I missed the launch because my spacesuit was at the dry cleaners.
When the reason clause comes after the main clause, no comma is needed before "because."
Since my spacesuit was at the dry cleaners, I missed the launch.
When the adverb clause of reason comes before the main clause, a comma is required after it.
The incorrect options:
"Because my spacesuit was at the dry cleaners I missed the launch." is wrong because a fronted adverb clause must be followed by a comma.
"I missed the launch, since, my spacesuit was at the dry cleaners." is wrong because "since" should not be surrounded by commas — it is a conjunction introducing a clause, not a parenthetical.
