Answer: C. As he sat on the curb in front of the school, Tico twirled a stick in his hand. Aunt Maricel would be there soon. Tico felt nervous because he knew she would ask about his trumpet, and he would have to explain everything.
Explanation:
The version that best uses a variety of sentence structures to enhance the flow and writing style of a story is option is C "As he sat on the curb in front of the school, Tico twirled a stick in his hand. Aunt Maricel would be there soon. Tico felt nervous
because he knew she would ask about his trumpet, and he would have to explain everything".
This is the right answer because all the other options are not structured properly. Option C enhances the flow as the option is structured properly as the words also flow along well.
The correct answer would be B) No because there is only one negative in the sentence and that would be ''aren't'' since that means are not, so since that's only one, and not two, its not a double.
