Since Hong Kong introduced liberal studies in secondary school curriculums, quite a few students have been asking to interview journalists from this newspaper about the most topical issues. Some questions are naïve, but more often they are intelligent and probing. It seems that the experiment by the education authorities, despite many hiccups and much criticism, has succeeded in stimulating deeper and less formulaic inquiry among youngsters.

This year's university entrance exam, the Hong Kong Diploma for Secondary Education, has included such previously taboo topics as the June 4, 1989 crackdown and the filibuster campaign in the legislature by some pan-democrats against various government proposals.

Some people think there are conspiracy theories as to why such topics have been introduced. Others have questioned whether secondary school graduates are equipped to address such topics adequately, that is, whether it is fair to ask such questions in a university entrance exam. That's nonsense. To have a reasonable viewpoint and an analytical explanation on such issues, all that a student needs is to have a serious interest in the topic. If a young person cannot deal with such topics analytically, you wonder if he or she is ready for university.
