| 1. In a study, shoppers who shopped in a grocery store without a shopping list and bought only items that were on sale for half price or less spent far more money on a comparable number of items than did shoppers in the same store who used a list and bought no sale items. which one of the following, if true, most helps to explain the apparent paradox in the study's results? A. only the shoppers who used a list used a shopping cart. B. the shoppers who did not use lists bought many unnecessary items. C. usually, only the most expensive items go on sale in grocery stores. D. the grocery store in the study carries many expansive items that few other grocery stores carry. E. the grocery store in the study places relatively few items on sale. 2. Recent studies have demonstrated that smokers are more likely than nonsmokers to develop heart disease. Other studies have established that smokers are more likely than others to drink caffeinated beverages. Therefore, even though drinking caffeinated beverages is not thought to be a cause of heart disease, there is a positive correlation between drinking caffeinated beverages and the development of heart disease. the argument's reasoning is most vulnerable to criticism on the grounds that the argument fails to take into account the possibility that A. smokers who drink caffeinated beverages are less likely to develop heart disease than smokers who do not drink caffeinated beverages. E. there is a common cause of both the development of heart disease and behaviors such as drinking caffeinated beverages and smoking. 各位大哥大姐们，这两道题我脑子晕乎了，怎么想也想不通了，第一题选C，第二题答案在A和E的其中一个，请赐教选哪个以及为什么另外一个错 谢谢各位！！！！！ |
