Hmm, it makes me think along the following lines:
Ultimately, an answer will lead to another question. The more questions are answered, the more questions will follow and allow more examiniations of perspectives/possibilities. Therefore, if an answer is always countered by a question the mind is 'forced' to think beyond boundaries, and thus engages in forms of enlightment.
.. Yer, but that spiral of thoughts just seems to bring up more questions 😉
