प्रश्न
Imagine if you had been in place of Dr. Beaumont, what experiments would you have done to find out the secrets of our stomach? Write about your experiments.
उत्तर
If I were in the place of Dr. Beaumont, I would have done experiments with boiled rice, chapatti, and salad. It would have taken out digestive juices from Martin’s stomach and would have kept equal amounts of boiled rice, chapatti, and salad in different glasses. I would have checked for the time it took to digest a particular food.
