the President Barack Obama was not called Gerald Ford in 1975 

Because it doesn't ask who WAS the president in 1975, it asks what the president (relating to the current president) name was in 1975. The answer quite clearly is Barack Obama, unless, he changed his name some time after 1975.

The questions were all exercises in semantics, I don't know why you would single out #8, that was one I didn't even have to think about.

but who in 1975 would have known about Barack Obama?

Oh FGS do some of you have to argue about every lttle thing? Is it because you didn't *get* it?

It's a bunch of riddles. After the first couple, most people would get that there's a catch in them.

Why does it matter whether he was known or not, he still had a name didn't he??

I failed number 8 ! maybe had I been not sotired and stressed I might have given it more thought. who knows    

LOL that's alright Twinks, I failed 7 and 11. :8}

They made complete sense when I read the answer though.
