Answer:
pipe
the question is saying that if cashiers work with cash, what do plumbers work with? Plumbers work with pipes, so the answer would be pipes.
Them would be the correct pronoun for this sentence because books is plural and is an object, so its pronoun must be third person. The 3rd person plural pronoun in English is they, and its objective/accusative form (the form used when the item is the object of a verb) is them, so there's your answer.
