单选题
What does the author mean to say when he talks about the damage caused by earthquakes to the buildings?
【正确答案】
C
【答案解析】[精解] 本题为推理题。在文章第三段作者提到,“While seismic engineering has improved dramatically in the past 10 to 15 years,every new quake reveals unexpected weakness in‘quake-resistant’structures”;在文章结尾,作者提到“every fault cannot be monitored and every highway cannot be completed quake-proofed.”可见,建筑物的防震能力是无法准确估计的。
