Even with all those hints in mind I had to look hard to see any of those differences. Only the 'O' was spelled out for Helvetica so even if I saw the difference I didn't know which font it was. I think I got about 6 right. I just can't tell the difference, as is always the case when these font discussions come up. Last time I learned what serif vs non-serif meant though.
