【正确答案】:
THE CONTEXT IS WORD STRUCTURE. 
QUATTROCENTO: "THE 15TH CENTURY AS A PERIOD IN ART AND ARCHITECTURE," 1847, FROM ITALIAN QUATTROCENTO, LITERALLY "FOUR HUNDRED," SHORT FOR MILLE QUATTROCENTO "ONE THOUSAND FOUR HUNDRED," IN REFERENCE TO A PERIOD BEGINNING IN "1400".
【题目解析】:本句使用的是词的结构法来猜测词义。Quattrocento:“十五世纪作为一个艺术和建筑时期”,1847年来自意大利,字面意思是“四百”,简称“一千四百”,指的是一个始于“1400”的时期。Quattro用来指代四, cento用来指代世纪。
