I am pleased that I scored 100% on my first try, though I suspect most (if not all) of you will do the same.

100%

That was amusing... now to get picky.

I can't decide, but I feel #10 is ambiguous enough to be wrong.

"Paris is in New Zealand." is not the same thing as
"Paris is wholely contained within New Zealand"

So if we answer this as a question posed on set membership (as implied by 'in') we have a problem. (Thus assuming Paris is a set not a element which is also part of the problem here)

As a logic statement:

There exists no x in Paris that is not also in New Zealand.
or
All members of Paris are members of New Zealand

rather than:

There exists an x in Paris in that is also in New Zealand.

Aargh. I missed the last two. I should have gotten #14 right, but I take issue with #15.
