Answer:
The correct answer is - The park was closed; therefore, we decided to play soccer in my backyard instead.
Step-by-step explanation:
Let’s go through the process of elimination to get to the correct option.
A) Is not correct because the conjunction BUT requires a comma, not a semicolon.
B) Is not correct because the semicolon here doesn’t make sense because of the order of words in the sentence. If the sentence said: I had gone for a long run during the day; however, my legs were not tired - then the semicolon would be correct.
C) Is not correct because the semicolon should come before the word STILL, not after it.
D) Is the correct answer as the semicolon is properly used to separate two independent sentences.
