Teacher: Given a set of five words, generate the word from the set that does not belong (i.e. is the least relevant) with the other words. Words are separated by commas.
Teacher: Now, understand the problem? If you are still confused, see the following example:
excavator, crane, pelican, hoist, upraise
Solution: pelican

Now, solve this instance: cards, deck, board, suits, knockout
Student:
knockout
