Step 1: Understand the meaning of the sentence
The sentence states that the person completed their assignment in relation to the ringing of the school bell.
Step 2: Determine the appropriate preposition of time
We need to choose the preposition that indicates when the completion of the assignment occurred in relation to the ringing of the school bell.
Step 3: Evaluate the options
Let's consider each option and determine if it fits the meaning of the sentence:
A: Since - This preposition indicates a starting point or a duration of time. It does not convey the specific timing in relation to the ringing of the school bell.
B: Before - This preposition indicates that the completion of the assignment occurred prior to the ringing of the school bell. This fits the meaning of the sentence.
C: By - This preposition indicates a deadline or a limit. It does not convey the specific timing in relation to the ringing of the school bell.
D: During - This preposition indicates that the completion of the assignment occurred while the school bell was ringing. This does not fit the meaning of the sentence.
Step 4: Choose the correct answer
Based on the evaluation, the correct answer is B: Before. This preposition accurately conveys that the assignment was completed prior to the ringing of the school bell.
Therefore, the completed sentence is: He had completed his assignment
before the school bell rang.
