Come up with a question and stream of consciousness reasoning that would justify this answer: 45
The question is: Sara is 6 inches taller than her brother Joe. Joe is 3 inches taller than his friend Roy. If Roy is 36 inches tall, how tall is Sara?
Stream of consciousness: Roy is 36 inches tall. Joe is 3 + 36 = 39 inches tall. Sara is 6 + 39 = 45 inches tall.
