【正确答案】正确答案： I totally agree that only under official laws or administrative regulations can we defend a stable and reliable examination system. An examination system needs laws and administrative regulations to keep stable. For example, in China, the Entrance Examination to College is held in a fixed time and processed in a strict way governed by related laws and regulations. Without these laws and regulations, it is impossible to hold such a national wide exams, and colleges would also find it impossible to recruit new students regularly. What's more, because this national exam is defended by consistent laws and regulations, the results of it are reliable and trustworthy so that universities and colleges in China can rely on these results to enroll students. In one word, without the defense of laws and regulations, an examination system would collapse very soon.
