Final answer:
Option B is the correct rewrite of the sentence because it uses the conjunction 'so' to effectively join the two clauses and accurately express the relationship of cause and effect. Option A, C, and D are less effective due to structure and punctuation issues.
Step-by-step explanation:
Which of the following would be a better way to write the sentence 'Alli wanted to celebrate her wedding with her coworkers she threw a bridal shower in the office break room'? The best option for rewriting this sentence to clearly express the cause-and-effect relationship between Alli's desire to celebrate and her action would be Option B: Alli wanted to celebrate her wedding with her coworkers, so she threw a bridal shower in the office break room. This option correctly uses the conjunction 'so' to join two related clauses, indicating that the action of throwing the bridal shower was a consequence of her wanting to celebrate.
Option A improperly leads with the action being taken before the reason, which is less effective for understanding cause and effect. Option C is not ideal because it places a comma before the semicolon, which is not correct punctuation for the structure of this sentence. Option D incorrectly suggests a contrast by using 'but', when in fact there is no contrast implied between Alli's desire to celebrate and her action.
