In response to the grim situation of frequent work-related accidents during building construction at that time, the relevant state departments issued the "Implementation Rules for Safety Production in the Construction Industry. " However, during the two years after the promulgation and implementation of the "Rules," statistics covering the whole country showed that employees were injured or injured during construction. The number is still increasing every year, which shows that the Rules have not been effectively implemented. Which of the following, if true, would most weaken the conclusion? ['In the two years after the promulgation of the Rules, the number of construction projects under construction has increased significantly.', 'In the two years after the promulgation of the Detailed Rules, the number of employees working in the construction industry has increased significantly.', 'In the above statistical results, the number of employees who died in accidents has decreased compared with before the promulgation of the Detailed Rules.', 'After the implementation of the Rules, the standards for compensation and pensions for workers injured at work have been improved.']
