单选题 Older persons typically exhibit greater experience-based knowledge, increased accuracy, better judgment, and generally improved ability to handle familiar tasks than younger persons. Such applied knowledge, or wisdom, may in fact be considerably more important to one's ability to accomplish most tasks of day-to-day life than were the abstract abilities tapped by intelligence tests.
A. increased accuracy
B. than younger persons
C. or wisdom
D. than were

【正确答案】 D

【答案解析】[解析] D项所在句使用了比较结构“Such applied knowledge…may in fact be…more important…than were the abstract abilities”。在比较级结构中，than后面可以倒装。从时态上看，句中的谓语都是一般现在时。因此“than were”应改为“than are”。
