From that quiz.org1. No mayten tree is deciduous, and all nondeciduous trees are evergreens. It follows that all mayten trees are evergreens.

2. Mike must belong to the Bartenders and Beverage Union Local 165, since almost every Los Vegas bartender does.

3. Either Colonel Mustard or Reverend Green killed Professor Plum. But whoever ran off with Mrs. White did not kill the professor. Since Reverend Green ran off with Mrs. White, Colonel Mustard killed Professor Plum.

4. I’ve never met a golden retriever with a nasty disposition. I bet there aren’t any.

5. Since some grapes are purple, and all grapes are fruit, some fruit is purple.

6. Why is Sarah so mean to Janice? The only thing I can think of is that she’s jealous. Jealousy is what’s making her mean.

7. Obama will make a fine president. After all, he made a fine senator.

8. The figure he drew has only three sides, so it isn’t a square.

9. It was the pizza that made my stomach churn. What else could it be? I was fine until I ate it.

10. It’s wrong to hurt someone’s feelings, and that is exactly what you are doing when you speak to me like that.
