The statistical results show that the number of college students receiving psychological counseling due to "psychological problems" has increased significantly in South Korea. Taking the Yonsei University Counseling Center as an example: 1,364 cases of consultation in 2003, and 3,485 cases in 2006, an increase of 1.5 times. The number of consultations at the University's College of Life and Culture also increased from 191 in 2004 to 285 in 2005 and 320 in 2006, showing an increasing trend year by year. Which of the following is true and can most seriously undermine the view that the reason for the sharp rise in consultations is the increase in psychological problems among college students? ['Increased mental pressure on future prospects and employment, and Korean college students suffering from mental pain have increased sharply.', 'Before 2004, college students in South Korea did not accept psychological counseling, even if they had psychological problems.', 'Investigation shows that in recent years, the case of a university consulting center in South Korea has shown a downward trend.', 'Since 2005, many universities in South Korea have established psychological counseling centers.']
