Underline the verb in parentheses that best completes each sentence. Spruce trees or oak trees (grow, grows) best in this type of climate.

The general rule is that the verb form should always be in accordance with the subject. First, we must locate the subject. Since the subject is a compound subject, make sure to identify whether the compound subject is plural or singular.

When the compound subject is linked by ‘or’, ‘either-or’, and ‘neither-nor’, the verb should be in accordance with the subject nearest to it.
