What do you mean by that?
if you could explain more clearly i'd be glad to help you out
The answer is one mystery that still remains unsolved is why we yawn.
and another theory is that when you yawn it sends oxygen to the brain causing your body to be able to stay awake, hence when you are tired and need to stay awake you yawn a lot.
The answer would most likely be C, because all the other options have to do with a job or manufacturer.
I'd say that the theme of this story encourages us that anyone can be important. Not just lawmakers or rich people or even extroverts, but anyone, whether you're a shy artist or an outgoing sporty-type. Some variation on that is probably what you're looking for, I shouldn't do your work for you! :)
