1. The reasoning could lead back to the original argument - "Why do you eat good food?" "Because it helps me live" "Why do you want to live?" "So that I can eat good food". Though this would be the fallacy of circular reasoning.
This is circular as you stated, and also subjective, which supposes assumption of correctness or validity.

One could then pose the question of 'why' in response to 'ask her' which would return to the original hypothesis.

This combines both my answers to 1 and 2.

These axioms cannot be called assumptions because no meaningful statement or argument can be made that don't assume the validity of these axioms. These don't have an answer to the "why" because the very concept of "why" depends on them.
"In traditional logic, an axiom or postulate is a proposition that is not proven or demonstrated but considered either to be self-evident or to define and delimit the realm of analysis. In other words, an axiom is a logical statement that is assumed to be true. Therefore, its truth is taken for granted, and serves as a starting point for deducing and inferring other (theory dependent) truths." - http://en.wikipedia.org/wiki/Axiom
