Question
If the sky is blue which of the following is true
It is a sunny day
It is daytime
It is cloudy.

Erm.
Its actually the first one.

The whole idea is to use the way a human parses the phrases as against the
way machines do it. Sadly, i suppose that they have to keep coming up with
new ones and as AI improves its a hiding to nothing anyway. You end up
having to employ somebody to watch out for spammers.

I would have said all of them could be true, assuming it's not entirely
cloudy.

I'd say it could be a dodgey question as we only see light scatter and not the actual sky, we can see clouds. Later the 'sky' may well turn red as the sun sets so I'd say the sky doesn't really have a colour but it wioll appear blue to our eyes because of the way blue light scatters and that;s what we see if there's no clouds and the sky is clear it looks blue.
