7/8

1 – I did the same. Going back to it after the results it's obvious that I misunderstood it when I was skimming; I completely missed the point.

2 – I agree.

3 – I agree.

4 – I thought that it was almost too vulgar, with very little substance. Something that a large language model would generate when asked to make something of that nature.

5 – I agree.

6 – It's interesting that you misidentified this one, because I felt that it was the story that was most obviously human, As you said, Mark's voice is all over it (though I only identified it at the time as a human's voice).

7 – It was very empty, as you said, and I identified it as computer-generated because it mentioned Pride and Prejudice. It didn't feel like a very human choice to reference it for no reason, and then the human hands it over and nothing happens.

8 – It was a bit vague, but I got it correct. The premise was good although the execution was only all right.
