Answer 1

It is not recommended to be using your own jquery version.

WordPress includes its own version of jquery and many other similar JS files, which have all been rigorously tested with WP and many of the most common plugins. In order to provide the best compatibility and experience for our users, we ask that you not package your own (especially not an older version) and instead use wp_enqueue_script() to pull in WordPress's version.

So you should use this instead:

wp_enqueue_script('jquery')
