I recently got 4 out of 10 logic questions right on an IQ test, so I'd like to improve my reasoning. When doing IQ questions I found this really nice website
that often also contains an explanation for the answers. However I don't understand why they one of the answers was selected and this one contains no explanation:
It states four conclusions that could possibly be true. I agree that A is true and D is false. But it seems to me C should be true instead of B.
Because the second statement "Some Ultas are Xanadorans" doens't justify an implication in the other direction, or does it?
Also, if "All Titanians are Ultas" then anything said about Ultas, also applies to Titanians, does it not?
