I found this quiz on my Facebook feed via Mental Floss. You're given a five-letter word with one letter missing. Only one letter will complete the word, and each letter of the alphabet can only be used once.
But beware. You only have 1:30 minutes to complete...
It took me three tries to get to 100%. The first time I got 73%. I missed one, and I ran out of time. The second time I got up to 80%, again missing one and running out of time. It goes quickly.
Try it. Some of the words are obvious. Some are a bit more tricky. Good luck.
