D的意思我一直不太明白“The relationship of the purchased item to the purchasing company’s end product” 有什么relationship好分?都是产品,就拿电脑来说,既是purchased item也是company's product呀
在来看我的答案A The ability of the purchasing company to subject potential suppliers of the purchased item to competitive scrutiny
文章开头第一句话告诉我们:In corporate purchasing, competitive scrutiny is typically limited to suppliers of items that are directly related to end products,很像文章的答案诶。
文章第一句只是是说competitive scrutiny is typically limited to suppliers of items that are directly related to end products,但没讲suppliers of items that are directly related to end products就不用 supplier parnership了。第二句说“indirect” purchases更favor supplier partnership,并不是说只有在这种情况下才用。所以D不对。
B是对的,因为:“supplier partnerships” (..)which can inappropriately shelter suppliers from rigorous competitive scrutiny that might afford the purchaser economic leverage.
