Egg, Banana, Apple, Walnut, Tangerine, and Avocado
The title sounds like a list of healthy foods. However, this list is from the homework I gave to my students.
Puzzle. Which one doesn’t belong: egg, banana, apple, walnut, tangerine, or avocado?
The book answer was apple as the only one which we can eat without peeling.
Other students suggested a lot of reasons why egg is the odd one out.
- Egg is the only one not grown from a plant.
- Egg is the only one without a letter a.
- Egg is the only one you can’t eat without cooking.
Overall, the students found reasons for each of them. In addition to the above, we have the following.
- Banana is the only one not in a spherical or ellipsoidal shape.
- Walnut is the only word without repeated letters.
- Tangerine is the only word with a square number of letters, and it is also the only citrus.
- Avocado is the only word with more vowels than consonants.
