单选题 What seems confusing and fragmented at first might well become ______ a third time.
A. clean and measurable B. notable and systematic
C. pure and wholesome D. clear and organic

【正确答案】 D

【答案解析】[解析] 从题意中可以看出需要选与confusing and fragmented(既令人困惑又零零碎碎的)意思相对的一组词，只有clear and organic(既清晰又有系统的)符合要求。A．clean and measurable(既干净又可度量的)；B．not able and systematic(值得注意的而且并系统的)；C．pure and wholesome(纯正的并有益的)都不符合题意。
