Answer:
B. Unless Christine finishes her calculus homework, she will have to suffer Mr. Nguyen's wrath in class tomorrow.
Explanation:
In the given sentences, the main errors to be focused on will be the use of punctuation, the commas, and the construction of the sentences. This will enable us to easily identify which sentence is the right one.
Looking at the sentence, the first part of it starts with a subordinating conjunction, thus making it a dependent clause. And as understood, dependent clauses cannot stand on their own as a complete or full sentence, they need an independent clause to be completed. Thus comes the second part of the sentence which is an independent clause.
Thus, when a dependent clause and an independent clause are together, and the dependent clause starts the sentence, then the separation of the two clauses is done by a comma. In this case, the comma will come in between "homework" and "she".
The final sentence will become
<em>"Unless Christine finishes her calculus homework, she will have to suffer Mr. Nguyen's wrath in class tomorrow."</em>
Thus, the correct answer is option B.
