单选题10. If either party wants to renew the contract, it should submit a written notice to the other party three months prior to the expiration of the contract.
【正确答案】
C
【答案解析】 renew意为“续借,续签”,a written notice意为“一份书面通知”,prior to意为“在……之前,居先”,three months prior to the expiration of the contract即为“在合同期满前三个月”。故只有选项C正确。
