Wait, we have to select two answers? I thought this was multiple choice, not a math competition. Where's the option for 'All of the above'?

I'm stumped on this one, looks like I need to brush up on my list operations. At least I can count on my trusty calculator to double-check the math!

I think the False equations are B) a [0]-1 ==b [0] and D) b[0] - 1 == a[0].

Haha, option A is a trap! Of course the lengths of the lists are going to be the same, they're assigned from each other. This exam is trying to catch us out!

I'm going with B and D - the indexing seems a bit off, and the subtraction doesn't seem to match up. Gotta be careful with those array manipulations!

I think you're right, B and D are the false equations.

Option C is definitely false, the assignment operator (=) is being used instead of the comparison operator (==). Rookie mistake!

Yes, that's a common mistake to confuse assignment operator with comparison operator.

I believe option D is also False because b[0] - 1 is not equal to a[0]. So, my choices are A and D.

I agree with Ammie. Option A is definitely False. What about the other options?

I think option A is False because len(a) is not equal to len(b).
