Premsingh is accurate, and this may clarify a couple of other points.
1. HubPages actually does not compensate any Hubbers for anything at all. All income to Hubbers comes from Google Adsense, eBay, or Amazon (and maybe other 3rd party sources.)
2. If the reader clicks an ad on the page with your hub, then, no, the asker of the question will not get anything.
3. If the reader clicks on an ad on the page where the question is, then the author of the question can make some Google Adsense earnings. But that is the same whether the question inspired a hub, or not.
Hope this helps!
