Does anyone learn/knows these answers by heart? Or do you just google, read, think to yourself "I see" and then move on? I am curious of how people approach this part of the chapter.

Shouldn't 5 be: "How do you add an archive to a directory?"

It looks correct. I guess the question here really is something like this: Assume you already have an archive and you want to add a new directory containing some files to it, how would you do so?
