Each group contains four unrelated words. Without rearranging the letters change one letter in each of the words to form four related words.
Example: rise, lilt, patsy, ires (answer: rose, lily, pansy, iris)
I technically just need help with two of the groups. They are:
1.) Snitch, Team, Cart, Threat
2.) Naif, Stable, Tact, Clump
