Read the paragraph below from the Introduction [paragraphs 1-3]. The human digestive system is like a long tube of organs. These
body parts include your mouth, throat, stomach and intestines. They break the food into pieces. Your body uses these pieces for energy. Special proteins help break down the food even more. The proteins are called enzymes. They are found in your spit and stomach. Enzymes help turn food into nutrients. Your body soaks up these nutrients. Then it gets rid of what it cannot break apart. That waste is your poop. Which question is answered in this paragraph? (A) Why is it so hard for the body to digest corn?
