The Book is going to launch a promotional campaign with subscriptions. If you subscribe to the Book for the second half of the year, you will receive a free weekly radio and television broadcast for the second half of the year. After the launch of the event, the newspaper will be published every day. In counting new subscribers, the results were very disappointing. Which of the following, if true, would best explain why this promotion failed? ['According to the statistics of the post office distribution department, the "Broadcast Television Weekly" is not a very attractive newspaper.', 'According to the results of a survey, some of the readers of the "Book Reader" have also subscribed to the "Broadcast and Television Weekly".', 'Broadcasting and Television Weekly has a wide distribution channel, with twice as many subscribers as Metro Youth Daily.', '"Reading News" did not consider the subscription habits of many people. Most newspaper subscribers had already subscribed to this year\'s "Broadcast Television Weekly" at the end of last year.']
