Come up with a question and stream of consciousness reasoning that would justify this answer: 19
The question is: Tim has 30 less apples than Martha, and Harry has half as many apples as Tim. If Martha has 68 apples, how many apples does Harry have?
Stream of consciousness: Tim has 68 - 30 = 38 apples. Harry has 38 / 2 = 19 apples.
