Answer:
The answer is C
Explanation:
A.) Because we are leaving early, we must check with our teachers about missing homework.
Believe it or not, you can start a sentence with "because" it just has to have a cause and effect.
Example:
Because it was raining outside, I took my umbrella.
You also have to add a coma after the "cause" of the sentence, as shown above.
Since the first answer choice meets both of these requirements, it is correct.
d
1. asteroid
2. spaceship
3. planet
4. solar system
5. astronaut
6. universe
7. alien
there you go! :)
