问题 Because of the enormous research and development expenditures required to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large.
选项 A、to survive
B、of firms to survive
C、for surviving
D、for survival
E、for firms’ survival
答案 B
解析 根据require的用法，马上可排除C、D、E。A看似很简洁，很多考生不假思索地就选了A。而读完全句，看到句末的such firms后，就会发现A有缺陷，若A对，则such firms中的firms应在此之前出现过，但前面并无firms出现。选B符合用法(2)，同时出现了firms。
