These lines of poetry from "totally like whatever, you know? " are most likely stated as a question for what purpose?

"invisible question marks and parenthetical (you know? )'s
have been attaching themselves to the ends of our sentences? "

to make fun of the manner of speaking that the writer is criticizing
to show that questions are always appropriate
to emphasize the speaker's confusion
to show that the speaker does not know how to use punctuation

explanation:

those are all the possible words

i decided to stay late in the laboratory to continue my experiment with the lightbulb. at midnight, thomas edison opened the door and walked in with his head held high.

1. he leaned on the wall and observed me carefully.

2. his harsh scrutiny made me self-conscious of my skills in the lab.

3. perhaps it was just me, but the air in the laboratory began to thicken as i found myself having difficulty to breathe.

4. i turned to look at him fully as i mentally prepared myself for what my very first words would be to thomas edison.

5. the next couple of seconds shocked me. it wasn't me who spoke, but rather him and with diction i could never think of using in a simple sentence.
