The Calex Telecommunications Company is planning to introduce cellular telephone service into isolated coastal areas of Caladia, a move which will require considerable investment. However, the only significant economic activity in these areas is small-scale coffee farming, and none of the coffee farmers make enough money to afford the monthly service fees that Calex would have to charge to make a profit. Nevertheless, Calex contends that making the service available to these farmers will be profitable. Which of the following, if true, provides the strongest support for Calex's contention? (A) Currently, Caladian coffee farmers are forced to sell their coffee to local buyers at whatever price those buyers choose to pay because the farmers are unable to remain in contact with outside buyers who generally offer higher prices. (B) In the coastal areas of Caladia where Calex proposes to introduce cellular telephone service, there is currently no fixed-line telephone service because fixed-line companies do not believe that they could recoup their investment. (C) A cellular telephone company can break even with a considerably smaller number of subscribers than a fixed-line company can, even in areas such as the Caladian coast, where there is no difficult terrain to drive up the costs of installing fixed lines. (D) Calex bases its monthly fees for cellular telephone service in a given region partly on the cost of installing the necessary equipment to provide the service there. (E) Calex has for years made a profit on cellular telephone service in Caladia's capital city, which is not far from the coastal region. 答案是A 我可以理解A的原因 不過B似乎也說得通 因為那邊沒室內電話 所以手機在那邊就會有很大的市場 C我也有考慮 手機公司可以在少量客戶的地方生存下來 似乎有點道理 只是我想說Caladia這地方的市場可能真的很小 即使是手機公司也活不下來 其實我選的是E 因為我想說在Caladia附近的環境應該都差不多 他能在附近獲利 應該也能在Caladia賺錢 不過我好像犯了自行假設題目的錯誤 orz 最主要還是B 為什麼B不行 是因為題目根本沒提到室話 所以跟室話無關嗎 --
