Here, question is misunderstood.
You need to either return <b>true</b> or <b>false</b>. Assume it's usage as:
<pre>
    random_keys = %w('all', 'alone', 'children')
    if verify_random_keys(random_keys)
        puts "At least few keys starts with 'a'."
    else 
        puts "None of my keys starts with 'a'."
    end
</pre>
