Add an example of an unhappy event occurring on a show, just as it would in real life.
Answer: Option C.
Step-by-step explanation:
In the last sentence of the second paragraph, the author could have added an example that showed an unhappy event which occurs on the show as a support of his argument.
The reason for this is that he needed to show his mother that every thing that happens does not have a happy ending all the time. Things in real life are much more difficult and do not have happy endings all the time. This will give a specific and concrete examples of what happens in the reality shows and they do not show very pleasant things.
