Medical diagnosis begins with a patient history, including a history of the present illness with a description of symptoms , a past medical history, and a family and social history.
【正确答案】 A
【答案解析】解析：symptoms“症状”，也就是指病人病情的“状况、表现”；clinical manifestations“临床表现”：clinical characteristics“临床特征，临床特色”；clinical prognosis“临床预后”；therapeutic signs“治疗的迹象”。分析句意，医生给出诊断应该要根据临床表现、以往病史等来判断。故选A。
