How to use both recapcha and q&a feature?

[Ra]

I ve noticed that recapcha does not set me free of the spambots.
But normally question makes robots stupidly stuck.
How to activate both functions?

It's one or the other, you can't enable both.

You will need an add-on to achieve that.

Enabling both will really do little to help over just a single one, while significantly annoying the humans filling out the form. Enabling Q&A and creating custom questions for your site is likely the best option. If you don't think that ReCAPTCHA is effective anyway, then there's no point in using it.
