Billy says that when he drinks liquid goes down one tube and when he eats, food goes down another tube. What did he say that is wrong?

What is the correct statement?

What are the facts you'd use to correct him?

Food and water go down the same tube which is called the esophagus.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
