Well turns out there is NO technically correct answer in the choices. I got it again today and I thought well I will try the 1025. I got DQ.
1000 is a correct answer but it kicks me out after that every time. Binary is 1024 but the closest to that is 1025.
Oh well. At least it is a kick out quick and you get a penny and can move on to something else. I just think it is sad that they say YOU need to pay attention to our survey and give thoughtful answers when they can't even give well thought out, makes sense questions, with all the words spelled correctly. I find mistakes in surveys constantly.
