Explanation
Correct answer: B.
Choice B is the best answer. This choice weakens the student’s conclusion by suggesting that the emotionality of movie reviews is related to box office success: the higher the emotionality score, the better the movie performs at the box office.
Why the other choices are wrong
Choice A
Choice A is incorrect. While this choice does mention emotionality scores, it only connects them to star ratings, not to box office success.
Choice C
Choice C is incorrect. The fact that many movies received an average star rating doesn’t tell us anything about the relationship between emotionality and box office success.
Choice D
Choice D is incorrect. While this choice suggests that star ratings can predict box office success, it doesn’t address the issue of emotionality in written reviews, which is the focus of the student’s conclusion.
