I believe the correct answer is that the <span>speaker may forget ideas or make grammatical mistakes.
Extemporaneous speaking has a lot to do with improvisation - it is a speech where you get a topic you haven't prepared for, and then you have 10-20 minutes to prepare and speak. This way, you cannot memorize everything that you wanted to say, and given that you aren't completely ready to speak, you may make some mistakes.
</span>
I believe the answer is "It does not state a life lesson, whereas a theme does"
It is a hyperbole since the teens literally cannot eat everything in their sight of eyes, what the line meant was that they ate every food in sight, not literally everything like a table or something unedible.
Hope this helped!
