Answer 1

The first script can be found in https://github.com/q2a/question2answer/blob/78b969da37468e8668559e3ffe23687ae5587129/qa-include/pages/question.php

If you think some scripts are suspicious you can search the unique texts in Q2A github respository (https://github.com/q2a/question2answer) .

This script is related to answer button, because the button is an ajax feature, it needs some javascript.

The second script is part of the  public function body_script() in https://github.com/q2a/question2answer/blob/7763be86aa74f839f8fad89d30f2130f72716189/qa-include/qa-theme-base.php
