Hello. You did not inform the wording to which this question refers, which makes it impossible for the question to be answered in a specific way. However, I will try to help you in the best possible way.
The homurous parts in an essay are those that present amusing statements, funny criticisms and punctuate situations that bring jokes and irony to a situation related to the theme of the essay. These phrases are funny because they touch playful evidence that can influence the reader to laugh and have fun with what has been said or read. You should look for that type of phrase to answer your question. Usually, in an essay, these phrases are made through criticisms, which are easily identifiable.
