beat the gmat 上面的解答
It is clear that Firestone actually set its IPO price TOO HIGH so definitely not slightly LOWER than it should have! Now, make sure you are clear about what it means to be inferable. If something is "inferable" then it can be shown to be TRUE given the information in the passage. We CANNOT show this statement to be true (it is clearly false) so we cannot infer it!
NOT Inferable
我也有这个疑问。OG13里面IR的第7题。解释说的是Firestone East Africa 的IPO price 比它的first day closing price高,题目中问:set its IPO slightly lower than it should have,所以要选Not Inferable. 但是,如果说,不论题目说法是否正确只要能根据信息推断就选inferable的话,这题应该选inferable啊…… 我现在就迷糊了。在IR里面,inferable和supported是不是一个概念啊……
