The mother had three pieces of sugar, two pieces of fudge, and one piece of toffee, and gave the two sons one piece each, and let them guess what kind of sugar the remaining piece was based on the sugar in their hands. The two sons sipped it after receiving the sugar. Then a clever one guessed it right away. From the above? ['Smarter kids get toffee.', 'The kid who did not guess was holding toffee.', 'Two people take one toffee and one take the fudge.', 'Both people took the fudge.']
