Question

Which of the following sentences is punctuated correctly?
A. Were you aware, that Daylight Savings Time begins tomorrow?
B. What most people do, is change their clocks in the morning, not the night before.
C. How you choose to wake up tomorrow, is up to you.
D. I hope that you do not oversleep, or we will be late for school.

Answer 1

is correct since the complete subject and complete predicate are separated by a comma which is allowed in a sentence therefore making a Cp,Cs sentence

Answer 2

The correct answer is D) I hope that you do not oversleep, or we will be late for school.
It is correct because in all of the other options, the comma is placed in an incorrect, weird place, breaking the sentence into incomplete fragments, whereas D is correct.
