How many regulations did the speaker introduce?

Câu hỏi :

Question 39 - 41 refer to following paragraph:

To respond to your question about how I became involved with political issues, I knew I wanted to become a politician from the time I was a child. After I began studying politics at Queen’s University, I knew that I had made the right career choice. When I became president of the university student council I had little time left to spend with my classmates. At age twenty-five, as student council president, I introduced twenty new regulations to try to change the atmosphere of the school. I was proud with what I had accomplished, but I was worried that I wouldn’t go beyond student-level politics. However, now after being recently elected as state governor, I am happy to have been given the chance to have become involved so early.
