18. (26912-!-item-!-188;#058&003382)

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.

不知道為啥咪, 我覺得(A)寫的很勉強.
雖然是有談到farmer的收入, 不過farmer's current 收入不高,
local buyers 都可以用低價來買coffee,
和前提談到的none of the coffee farmers make enough money to afford the monthly service fees that Calex would have to charge to make a profit 相關,

這樣怎麼會讓Calex的營收成長呢?? *-)

沒有通訊,東西賣不出城,只能低價賣在本地;有了遠距通訊,東西就可以賣給出高價的外地客戶.遠距通訊對當地居民有好處,當然居民就願意使用啦!

(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.

這個選項是不是代表farmers別無選擇 一定會接受cellular telephone呢?

(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.
有人可以翻譯一下這個選項嗎? thx

我想這個選項是說"Caladia居民目前沒有有線電話可以使用"但如果推論到"farmer一定會接受手機"好像就有點超過範圍了
而且推論重點是要說明Calex Telecommunications Company 認為儘管沒人現在付的起電話費,但未來仍是會獲利
所以說明其他電話服務的狀況沒辦法加強推論

(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.

手機公司比有線電話公司需要較少的用戶就可以達到損益兩平,即使在Caladian coast這種地形起伏平緩而電話線公司成本不會上升的地方(手機公司還是需要較少的用戶就可以損益兩平)

原來最後一句話是這個意思呀 我還以為為什麼手機公司要在地形崎嶇的地方把成本調高...
thanks..
