argument133的疑问

TOPIC：ARGUMENT 133 - The following is a memo from the principal of Academia High School.

"Academia High School should abolish its after-school performing-arts programs and replace them with computer-technology programs. When nearby Techno High School did so last year, total enrollment in all of its after-school activities remained about the same. Moreover, on entering college, many Techno students chose a major directly related to their after-school activities. On the other hand, last year only 10 percent of Academia's graduating seniors chose performing arts as their major field of study in their first year of college, clearly indicating that most students do not have a strong interest in the performing arts."



作者的结论是第一句话，而其中两个论据是关于T的，不明白：
1.T高中采取变化后课外活动参加人数总量没变——作者利用这个论据想要说明什么呢？
2.T学生走入大学后择业与其高中所参加活动直接相关——作者利用这个论据想要说明什么呢？
按作者的意思，这两个论据是怎样支持结论的呢？
还是想利用第二个论据说明A也是这种情况，推出10％选择艺术作为专业即10%选择艺术课程？


实在看不懂作者的逻辑，望达人赐教，谢谢！
