The _____ talks between China and the United States were the base of the later agreement.
【正确答案】
C
【答案解析】解析:考查形容词辨析。由base一词可知答案为initial“最初的,开始的(beginning)”。original意为“最早的,最先的(first,earliest)”;primary指在时间、顺序或发展上领先的,意为“第一的,基本的,主要的(leading in time,order or development)”;primitive意为“原始的(of an early stage of social development)”。
