Answer: C. Eugene can claim to know everything but still not know everything, a behavior which may fit better as a teenager, thus making him it more believably human.
Explanation:
You didn't give the passage where you got the options from and I couldn't get it online as well but based on some information gathered online, the answer is option C.
The option that summarizes the advantage(s) of the program's teen persona is that Eugene can claim to know everything but still not know everything, a behavior which may fit better as a teenager, thus making him it more believably human.
Therefore, the correct option is C.
Can we get the answer choices?
When you switch the sentence around such that the subject is being acted upon.
Here's what a sentence with active voice would look like:
John kicked the ball.
In this sentence, John is the subject, and he's kicking a ball. The subject is acting upon an object.
Now, what would happen if we made the ball the subject instead?
The ball was kicked by John.
This is passive voice. The ball is the subject, and it was acted upon by an object, in this case John.
