Answer:
it begins with a salutation<em> </em>
Answer: the answer would be "go"
Explanation:
this is because it is improper to say "goes" when talking about two people and it the sentence is also in present tense.
My guess would be d. previously, because it's talking about early cars.
The correct answer is "of the children". This adjectival phrase is used to modify and further explain the noun "voices".
