你好同學(xué)
這道題是原版書課后題。原版書中的練習(xí)題會(huì)出現(xiàn)例如多選題，填空題，判斷題，case題之類的題型。但也只是為了練習(xí)或者鞏固知識(shí)點(diǎn)使用。并且這類題型有個(gè)特點(diǎn)，有幾率會(huì)出現(xiàn)考綱之外的延伸的知識(shí)點(diǎn)。實(shí)際上同學(xué)在做練習(xí)的時(shí)候完全可以跳過(guò)這些類型的題目，對(duì)考試成績(jī)基本不會(huì)有影響。如果時(shí)間充足的話也可以做一下，或者直接翻看答案看看這道題想要考察什么或者提供了哪些課外知識(shí)。
這道題的答案可以參考原版書給出的解釋：
E is correct. The resume preparation service benefits from the network effects
on various online job sites, but the service is not the source of those network
effects. Each of the other businesses (A, B, C, and D) becomes more valuable to
its customers as it attracts users. A stock exchange is valuable and worth joining
because many securities trade on it. The telephone network is very useful because
most people are on it. A classified advertising website becomes more useful as it
attracts more listings. An airfare price comparison website is valuable to airlines
because it has many shoppers and valuable to shoppers because it features prices
for multiple airlines and routes.
