First, with imported stylesheets they mean stylesheets embedded using the @import rule.

Second, a few lines below that explanation in the CSS 2.1 spec there's an explanation of the cascading order. Other parts of the spec might be useful for your exam, too. Good luck.

Update: A bit of googling resulted in:

@Marcel Korpel : Thanks for the links, definitely helpful.
Michael Mao
@Marcel Korpel : so can you say that what's in the slide is not correct?

@Marcel Korpel : I always forget to put the + among keywords :( Thanks for the links, now I can tell why the slide would get such a weird statement to me :) I hope in exam it wouldn't get too much on this tricky topic.
Michael Mao
@Michael: the +? You mean when doing a Google search? You can just enter spaces in the search field.
