One of the four words does not belong with the other three. Which word does not belong? What is it that the others have in common?
1. Green, yellow, red, blue.
2. April, December, November, June.
3. Cirrus, calculus, cumulus, stratus.
4. Carrots, radishes, potatoes, cabbages.
5. Fork, comb, rake, shovel.
2) December, Because the other three months all have 30 days except December.
3) Calculus, because the other three are cloud types while calculus is a part of Math.
4) Cabbages, because that grows above soil. Carrot, Radishes and Potatoes (they are tubers) grow underground.
5) Shovel, because the other three have teeth kind of design.
