Directions: The question has four items. Select the word that does not belong to the group.

The question asks to identify the word that doesn't belong. 'Rancid', 'Tainted', and 'Sour' all describe unpleasant or spoiled qualities - typically used for food or smells that have gone bad. 'Toothsome' means pleasant or agreeable to the taste - it's the only positive word in the group. While the other three describe something bad or spoiled, toothsome describes something good or enjoyable.
