In test suite problem 25, there seems to be an issue with the question mark after 'Africa'. The word Africa itself is a prime word, but the solution marks it as non-prime. Since the question mark is usually considered punctuation, I treated it as a space.
Thanks William. I fixed the test (and my own code).
