79.An overly centralized economy, not the changes in the climate, is responsible for the poor agricultural production in Country X since its new government came to power. Neighboring Country Y has experienced the same climatic conditions, but while agricultural production has been falling in Country X, it has been rising in Country Y.
Which of the following, if true, would most weaken the argument above?
(A) Industrial production also is declining in Country X.
(B) Whereas Country Y is landlocked, Country X has a major seaport.
(C) Both Country X and Country Y have been experiencing drought conditions.
(D) The crops that have always been grown in Country X are different from those that have always been grown in Country Y.
(E) Country X's new government instituted a centralized economy with the intention of ensuring an equitable distribution of goods.
Argument Evaluation
Situation Two countries sharing similar climatic conditions differ widely in agricultural production, one experiencing a rise and the other a decline. The decline is blamed on an overly centralized economy.
Reasoning What point most weakens the argument that the economy is to blame? If a factor other than the economy could account for the differences in agricultural production, then the argument is weakened. If the two countries grow different kinds of crops that may react differently to the same climatic conditions, then the types of crops, rather than the economy, could be responsible for the differences in production.
A The economy might indeed be to blame for declining industrial production, which would strengthen the argument,(为什么会加强呢?明明是无关)OG10的解释是The information in choice A cannot be evaluated without more information about industries in Countries X, but not enough information is given about the country's industry to allow that evaluation of blame to be made.
B The availability of a seaport does not explain the differences in agricultural production.
C Similar climatic conditions have already been established in the argument.
