Final answer:
The statement is true; in sign languages, combining a sign with the AGENT sign is used to denote jobs or occupations.
Step-by-step explanation:
The statement that combining a sign with the sign for AGENT indicates a person does a job or occupation is true.
In sign languages, agent markers or agent signs are often used to transform words into nouns that denote a person who performs the action of the verb. For instance, the sign for "teach" combined with the AGENT sign refers to a "teacher," thus indicating the job or occupation of the person who teaches.
