In this exercise, you'll see input verbs and model verbs. If you choose ring as your model verb, and then bring as your input verb, bring will conjugate the way that ring normally does.
Correctly conjugated verbs communicate to a reader or a listener the meaning behind the the sentence clearly. You can see that in English, the verb to be changes depending on who is the subject.
