It seems that this question is asking for you to create a hook for an essay about what you think it means to be an adult.
A hook is the first few sentences of an essay that is used to "hook" and grab the reader's attention. Hooks can be personal anecdotes, rhetorical questions, or anything else that is compelling to the readers.
The hook should be relevant to the topic. It should also insinuate what you are going to argue for.
So, let's compose some sentences that could start off an essay in an interesting way (aka the hook). Here is an example hook I have made:
Example Hook: Every kid has that dream of how it is to be like an adult. But, how do they see it? Do they believe it is fun and exciting? Do they believe it is scary and stressful? How do other younger people see life as an adult?
If this is a response you should write by yourself, I would recommend composing your own hook, but this should give you a basic idea. Hope this helps! :)
Of course, if you have additional questions, feel free to comment!
