After а lоt оf wоrk building аnd stаrting his backyard organic spinach farm, Jeremiah has finally harvested his first load of spinach. He has contracted with Two Girls and a Van, a commercial shipping company, to load his spinach into their van and deliver it to a market on the other side of the state who has purchased the spinach from Jeremiah. Because Two Girls and a Van is a savvy shipping operation, they track the load of spinach using a written document that verifies how much spinach is in the shipment and the time it was loaded at Jeremiah's house and unloaded at the market. What is the name of this document that Two Girls and a Van uses to keep a record of this shipment of spinach?
