【正确答案】During the period between 2000 and 2005, pirated software users declined abruptly from 3,000 to 800, while authorized users increased sharply from 2,000 to 9,000.
Several reasons can account for this phenomenon. Compared with pirated software, authorized software can guarantee both high quality and good after-sale service. Apart from that, authorized software are becoming cheaper and cheaper—-more and more people can afford them.
