Wait, did they just throw a bunch of random numbers into a list and expect us to make sense of it? Sounds like a typical programmer's idea of a good time.

D, definitely D. That's my final answer, and I'm sticking to it like a piece of chewing gum on the underside of a desk.

Hmm, I'm not sure about this one. Maybe I should've paid more attention in that C++ class instead of doodling unicorns in my notebook.

Haha, I'm gonna go with B. Who needs to sort lists when you can just randomly rearrange them?

The correct answer is C. The code sorts the first list, then splices the elements from the second list starting from the third element (index 2) to the end of the second list, and appends them to the end of the first list. This results in the output: 1 3 4 5.
