What you really mean with this question is not clear. But i think you've got a small misunderstanding here. Hubpages and Amazon is entirely two independent websites.
Also, its not clear what you mean by "another tasks", we can't click on our own ads i guess, but we're to write articles about various topics of our choice and interest. Hubpages will place ads for us in our articles so that a certain % of the commissions is shared between us and hubpages.
Hope that helps,
Happy to Help,
