Question

pick out the modal auxiliary and state its function. a) We ought to look after our old parents​

Answer 1

Explanation:

Modal verbs are auxiliary verbs (also called helping verbs) like can, will, could, shall, must, would, might, and should. After a modal verb, the root form of a verb is generally used. The word to should not appear after a modal verb. An exception is the phrase ought to, which is considered a modal verb.
