The consequences of this attitude are, in fact, far-reaching. Young people apply for jobs, or to take courses in tertiary education, and demonstrate in their letters of application that they cannot speak English properly.

选自Simon Heffer 的《Strictly English》page 20

疑问1：to take courses in tertiary education 是作时间状语吗？动词不定式能作时间状语吗？若分析成目的状语似乎和后面的demonstrate似乎又不搭。

疑问2：如能作状语，这里的or（or to take courses in tertiary education）怎么理解？

谢谢回答。
