Hi there - can you please explain why statement 2 is not a tautology? It simply repeats what the question already tells us (and therefore is not sufficient). That's what i first thought!

Hi Alan! Excellent question :) The prompt itself only tells us that x < 0 and y < 0. The question we need to answer is if the information in statements 1 and 2 is sufficient to determine whether x < 10 < y. Again, we're not told that x < 10 < y originally but rather asked if we can determine if this is true :) I hope this clears up your doubts! If not, please let us know! Happy studying :D
