Interesting... I already recieved confirmation that for #11, 2 is the correct answer. And when I submitted 4.10 for #12, that was marked incorrect. All the other answers were correct, so thank you very much for this. I have submitted this question many times and everyone keeps giving me wrong answers. You were the first to give me correct answers. Do you know why 4.10 would be marked incorrect for 12 and why #11 would be correct with an answer of 2?
