Which is the odd one out: Carrot, Potato, Beetroot, Cabbage
So we might say that Cabbage is the odd one out because the others are root vegetables...
But Potato is also the odd one out because the other words all have double letters.
We're looking for solutions to this equation:
"X is the odd one out because the others have property Y and X doesn't have property Y."
These are some possible (X,Y) solutions:
Y = is a root vegetable, and X = Cabbage
Y = is a word with double letters, and X = Potato
Y = is a word with a T in it, and X = Cabbage
Y = is a word with an O in it, and X = Cabbage
Y = is a word with an A in it, and X = Beetroot
Y = doesn't stain one's fingers, and X = Beetroot
Why should one particular Y take precedence over any other? The question is ambiguous.
Y = not being a carrot. X = Carrot.
Carrot is the odd one out because all the others are not carrots.
It's supposed to be a test of logic, yet the question is logically absurd.
The tester probably wants us to think of root vegetables and not vowels here. But why should this property take precedence over any of the others? Why are we encouraged to interpret that way?
The question is really this: "Why are root vegetables more important than vowels?"
