How is humor used in this excerpt to effectively critique marriage?

  plan: i will begin with a quotation about the importance of unity in a community. then, i will state my claim that an activity will unite our school by creating a shared vision, purpose, and direction. in the body, i will use three main points that describe the different avenues the students can take: through a variety of clubs, through a special event, or through an awareness week. i will provide evidence about other towns that have unity activities and the kinds of events that they include. pictures will illustrate my three main points in action. for the ending, i will restate the main idea in a new way and pose a question to keep the audience thinking. 

ok then i guess ill just randomly post this comment

i read this story but basically they wanted to be free from their troubling minds. if i had the answer choices it would be better for me to answer this question.

the statement that best summarizes samantha's claim is c. fast food restaurants would profit from offering vegan meals.

samantha explains her experience as a vegan going to eat to fast food restaurants and she concludes her argument by saying "by not offering vegan meals, fast food restaurants are missing out on additional sales." in this conclusion, readers can infer that samantha believes fast food restaurants would increase their sales if they offered vegan meals and, thus, profit from it.
