Final answer:
Quantities are likely to be blinded on a purchase order sent to the receiving department to ensure unbiased verification of the goods received without influence from expected amounts.
Step-by-step explanation:
The question pertains to the common practice in business operations where certain information is 'blinded' or omitted from documentation when sent to different departments within a company. In the context of a purchase order, the detail that is most likely to be blinded on a copy sent to the receiving department is the quantities. This is because the receiving department's responsibility is primarily to confirm that the items received match the description and quality standards, without being influenced by price or quantity information. Therefore, it ensures that the receiving personnel verify the inventory based solely on the actual items received, not the number expected, which helps prevent confirmation bias or errors in counting.
