[单项选择]The importer will require a full set of bills of lading in order to obtain the goods from overseas port. The bills of lading can only be obtained by payment of the bill of exchange (D/P), or by acceptance (D/A). Therefore, the importer cannot obtain the goods without paying or accepting the bill of exchange, and conversely an exporter retains control of the goods until payment or acceptance of bill of exchange. When goods are sent by air, the airway bill could show the importer’s bank as consignee. Once again the importer must pay or accept a bill of exchange to be able to obtain the goods. Once the importer has paid or accepted the bill of exchange, the importer’s bank will issue a delivery order. The delivery order is an authority, signed on behalf of the bank, authorizing the airport to release the goods to the named importer. An exporter should obtain the prior agreement of the importer’s bank before he consigns goods to that bank. In practice, the importer’s bank will not agree to

B. the declining number of doctors
C. the shrinking primary care resources
D. the ever-rising healthcare costs
