C is a no-brainer, always true!

Wait, v1 and v2 can be equal? That seems unlikely!

A is false, len can't be > 2 with sample size 2.

I feel like `v1 >= 1` is definitely wrong since `random.random()` gives values between 0 and 1.

I think `random.choice([1,2,3]) >= 1` will always be true because the minimum value is 1.

I'm not sure about `v1 == v2`, since they are both random values, they might not be equal.

I remember that `len(random.sample([1,2,3],2))` should be 2, so that can't be true.

I'm not sure about this one. I might need to ask the instructor for some clarification before I can attempt to solve it.

I'm pretty confident I know the answer to this one. The key is understanding how the random functions work and their expected outputs.

Okay, I've got a strategy. I'll evaluate each expression and see which ones are always true, regardless of the random values.

Hmm, I'm a bit confused by the random.sample() function. I'll need to double-check the documentation on that one.

This one looks tricky, but I think I can figure it out. Let me think through the random functions and their expected behavior.

Wait, are we supposed to be picking the answers or making funny comments? I'm torn between cracking jokes about the random module and actually trying to solve this problem. Decisions, decisions...

Option D is tempting, but I don't think it's a safe bet. The random.random() function can return any value between 0 and 1, so there's no guarantee that v1 will always be greater than or equal to 1. Gotta think this through carefully.

Haha, option A is a bit of a trap, isn't it? You'd think selecting two random numbers from a list of three would always be less than 2, but I guess the random module has a few surprises up its sleeve.

I'm feeling lucky with option C! Random.choice() will always return one of the values in the list, and they're all greater than or equal to 1, so this should be a guaranteed winner.

User2: I'm not so sure about that. I'm leaning towards option B because v1 and v2 are generated randomly, so they could be equal.

User1: I think option A is also a safe bet. If we sample 2 elements from a list of 3, the length will always be greater than 2.

Hmm, option B? The random.random() function generates a random float between 0 and 1, so the chance of v1 being equal to v2 is pretty slim. Gotta go with the odds on this one.

I believe option C is also True, as it checks for the existence of a method 'get' in object B.
