Answer: record; studies
Explanation: For sentences written in the present tense with third person subjects, it may be handy to remember that the subject and verb "share one 's' between them.
Regular plural subjects end in -s. The verb will not have the -s ending. (Irregular plural nouns and pronouns don't end in -s, but the idea is the same: id the subject is plural, the present tense verb does not have the added -s)
If the subject is singular and "third person" (not referring to I, or you) the simple present tense verb always ends in -s.
This is true even for irregular verbs! She is kind. He has a nice smile. It does a good job.
