After a TV variety show was broadcast, the show director claimed that the show had reached the highest level of current similar programs because the show had a 2% higher ratings than similar programs. Which of the following, if true, would most weaken the argument? ['The guests participating in the show have different opinions on the show.', 'Audiences themselves enjoy watching TV variety shows.', "The director's Weibo has hundreds of thousands of comments criticizing the show.", 'The level of the program is not necessarily related to the ratings.']
