The best way to eliminate wordiness is the following:
<em> The audience gave the guest speaker a standing ovation.</em>
Wordiness is the use of more words than necessary to express an idea. The phrase <em>"to give a standing ovation"</em> already comprises the ideas of "rose up" and <em>"applauded"</em>. Thus, they are not necessary in the sentence. Replacing those words with the words <em>"gave the guest speaker a standing ovation"</em> is the right way to eliminate wordiness in that sentence.
The dialogue shows that Furtunato thinks Montrsor is playing a joke on him.
