Final answer:
An invoice and a packing slip would be included with a document delivery from a reliable supplier but raw materials would not, as they are not associated with the delivery of a document.
Step-by-step explanation:
When ordering a document from a reliable supplier, items typically included in the delivery would be an invoice and a packing slip. The invoice serves as a bill for the purchase, detailing the items bought and the total cost due. The packing slip, on the other hand, is a detailed list of the items included in the shipment, which helps the receiving party to verify the contents against the order. However, raw materials would not be delivered with a document, as raw materials are physical items used in the manufacturing or production process and are not associated with the delivery of a document. Perishable goods might be delivered with documents if they are the items ordered, but they are not directly related to the delivery of a document itself.
