166.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.
(A) to survive
(B) of firms to survive (C) for surviving
(D) for survival (E) for firms’survivalIn choice E, the illogical and awkward use of a prepositional phrase (for firms’ survival) buries the needed initial reference to firms in a possessive modifier 正确答案B。别的也没什么疑问，只是OG对E选项的解释我看不大明白，希望NN帮我解释一下上面的绿字。谢谢
