Answer:
6. Dan said that this was the best dinner he has ever had
Both are a number (6) multiplied by a variable (z).
However, 6z is the correct way to write this.
We usually write the number first, that's just the way it's done.
It sort of makes sense because 6z is literally equal to 6 z's.
I believe the correct answer is the second sentence: What
have been the effects on the state bans on driving and texting.
Open-ended questions are those which require putting more
though while answering, as opposed to the closed-ended questions which can be
answered by a simple "yes" or "no". In this case, the
second sentence requires a longer explanation on the effects of the state bans on
the driving and texting.
The answer is C. streamers and balloons because it has the conjunction and in the subject and is talking about 2 nouns in the subject, making it a compound subject.
