Really? I thought queues couldn't be instantiated from vectors.

Line II looks good too, using a deque.

Wait, line IV? That's not right, you can't use a list!

I remember something about queues not being able to take lists or vectors as parameters, so lines IV and V might be wrong.

Line III seems okay because it’s copying another queue, but I can't remember if that's always valid.

I'm not sure about line II; I feel like you can't initialize a queue with a deque directly.

I think line I is definitely correct since it shows a simple instantiation of a queue.

Okay, let's see... If I get an RST packet, that means the port is closed, right? Or wait, is it the other way around?

Alright, I've got this. The odds ratio of 1.142 means the odds of the event are 1.142 times greater for each one thousand dollar increase in salary. So the correct answer is B.

This looks like a straightforward URL link question. I'm confident I can identify the correct answer.
