What does this warning message mean?
Underfull \hbox (badness 10000) in paragraph at lines 49--50
This is my code, I can't see what happens, it is a simple itemize. As you see, there is an admiration symbol, I don't know what is going on.
I have also this warning, another admiration symbol:
Underfull \hbox (badness 6893) in paragraph at lines 77--78
I am working in article as class document. That is just text, no reference mode.
