For the sake of this discussion, yes.

They return query results, which are a sequence of record objects.

Yes.

If you tell it to, check out the 'Advanced' tab on ZSQL Methods. 
(First, don't forget to specify one argument to the method or else you
won't see what I'm talking about).

First it finds Flavor, then it traversed into Flavor, then Flavor find
the next element as its argument (once again, if you tell it to).  So
essentially the answer is yes.

Yes.

If rss wasn't there and it was in your URL then you would get a 404
NotFoundError.  If 'Cherry' is your last argument then yes, it would
acquire the first 'index_html' object that it found, which in this case
is the one in the root folder.
