31. 木木周: 是说citrus fruit 价格上涨，但是在13年中只有一年的气候不适合citrus crops 的生长，所以肯定是growers 过度涨价导致了citrus fruit 价格膨胀，所以应该strict price regulation。
V1 argument是一篇editorial 说一个地区decades以来Citrus的价格涨了非常多，给出了一个柠檬涨价多少的数据。然后这里11年来只有过一次的unfavorable weather，然后好像没啥重要的了，就得出结论这样橘子的涨价要归咎于 growers。 (感谢chenr523 )
题库原题：92. The following is taken from an editorial in a local newspaper.
“Over the past decade, the price per pound of citrus fruit has increased substantially. Eleven years ago, Megamart charged 5 cents apiece for lemons, but today it commonly charges over 30 cents apiece. In only one of these last eleven years was the weather unfavorable for growing citrus crops. Evidently, then, citrus growers have been responsible for the excessive increase in the price of citrus fruit, and strict pricing regulations are needed to prevent them from continuing to inflate prices.”
In this editorial the author argues for the imposition of strict pricing regulations in order to prevent citrus growers from continued inflation of prices of citrus fruit. The need for such regulation is supported by the author’s contention that citrus growers have been unnecessarily raising prices of citrus fruit in the past. The evidence for this allegation is the fact that the price of lemons at Megamart has increased from 15 cents per pound to over a dollar a pound during the preceding 11-year period. The author maintains that this increase is unjustifiable because weather conditions have been favorable to citrus production in all but one of those years. This argument is flawed for several reasons.
First and foremost, the author assumes that the only factor that influences the price of citrus fruit is the weather. Other factors such as monetary inflation, increased distribution and labor costs, or alterations in supply and demand conditions are completely ignored as possible sources for the increase. The charge that citrus growers have unnecessarily raised prices can be sustained only if these and other possible factors can be completely ruled out as contributing to the price increases. Since the author fails to address these factors, the recommendation calling for strict pricing regulations can be dismissed out of hand (adv. 无法控制, 脱手, 告终, 立即) as frivolous.
Second, the author assumes that the only way to combat increased prices is through government intervention. In a free enterprise system many other means of affecting the pricing of goods are available. For example, boycotting a product and thereby influencing supply and demand conditions of the commodity is an effective means of influencing the price of the product. In a free market economy the call for price regulation by the government should occur only when all other means to rectify the problem have been exhausted.
In conclusion, the author’s argument is unconvincing. To strengthen the argument it would be necessary to show that the only factor influencing the price increases is the growers’ desire for increased profits.
