Q: How can I send the recovery email to reset my security questions?

If you have a rescue email address (which is not the same thing as an alternate email address) on your account then steps 1 to 5 half-way down this page will give you a reset link on your account : http://support.apple.com/kb/HT5312

If you don't have a rescue email address (you won't be able to add one until you can answer your questions) then you will need to contact Support in your country to get the questions reset.

Contacting Apple about account security : http://support.apple.com/kb/HT5699

When they've been reset (and if you don't already have a rescue email address) you can then use the steps half-way down the HT5312 link above to add a rescue email address for potential future use
