Poll Survey

I did my poll twice, the first time I asked "How are AIDs transmitted?" A. Sex B. Needles C. Breast Feeding D. All of the above. And it was to obvious, eight people voted and they all voted All of the above.
My second one I asked "How are AIDs transmitted?" But I asked it on facebook this time. This is what I said:

Hey everyone!

So I need to get ten answers for my poll for my English class....
If you could answer one of these questions, A-D that'd be great.
I need ten people!! :)
...
How is AIDs transmitted?

A. Only Sex & Needles
B. Water
C. Physical Touch
D. Breast Milk

Thanks!!

Almost everyone except one girl said D, which was the answer. Everyone else said A & D but they didn't read it correctly. Because if AIDs is transmitted through JUST sex and needles then it can not be breast feeding as well. So its a bit irritating they didnt read it right, so both polls were incomplete. Although two girls said A, which is usually what is assumed to be the only way for AIDs to be transmitted.
Wish one of the polls would have came out right.
