Q32. Which type of declaration will take precedence?
  any declarations in user-agent stylesheets <<<<---Correct
  important declarations in user stylesheets
  normal declarations in author stylesheets
  important declarations in author stylesheets

That's wrong. In fact, declarations in user-agent stylesheets have the lowest precedence. Otherwise, no other CSS would have any effect.

The mark note for algiorithms often looks like this:

apply(note1);
apply(note2);
apply(note3);
...

It would be more convenient to write

apply(note1, note2, note3, ...)
