（1） 因果条件题题型举例

Vegetables and chicken cost more when they have been cut into pieces by someone other than the one who buys it. A family should expect to pay more when several “TV dinners” are taken home from the store. These are fully cooked meals， consisting of meat， vegetables， and sometimes desert， all arranged on a metal dish. The dish is put into the oven and heated while the housewife is doing something else. Such a convenience costs money. (44）

[A] Thus， as economists point out： “Some of the basic reasons for widening food price spreads are easily traceable to the increasing use of convenience foods， which transfer much of the time and work of meal preparation from the kitchen to the food processor’s plant.”

[B] They are among the “middlemen” who stand between the farmer and the people who buy and eat the food. Are middlemen the ones to blame for rising food prices?

题解：

因果条件题是逻辑关系题中最常出现的一种类型。例如本题，根据段落意思， 可以判断44题是一道因果结论题， 所以选A。
