Which of the following can best explain the above contradiction? ['Some elderly people think that the content of the program is not significant for health.', 'The packaging of the show is too entertaining and does not meet the needs of the elderly.', 'Watching TV for too long is not good for the health of the elderly.', 'The program aired late, at this time most elderly people have already rested.']
