第二段：The chief problem was technological:How were the Europeans to reach the East?Europe's maritime tradition had developed in the context of easily navigable seas—the Mediterranean,the Baltic,and.to a lesser extent,the North Sea between England and the Continent—not of vast oceans.New types of ships were needed,new methods of finding one's way,new techniques for financing so vast a scheme.The sheer scale of the investment it took to begin commercial expansion at sea reflects the immensity of the profits that such East-West trade could create Spices were the most sought-after commodities.Spices not only dramatically improved the taste of the European diet but also were used to manufacture perfumes and certain medicines.But even high-priced commodities like spices had to be transported in large bulk in order to justify the expense and trouble of sailing around the African continent all the way to India and China.
6.It can be inferred from paragraph 2 that spices from Asia were desirable in Europe in the Middle Ages because they
○were easily transported in large quantities
○could not be produced in European countries
○could be traded for products such as perfumes and medicines
○were expected to increase in value over time
文中说的是香料不仅能吃还可以用来做香水和药,而第三个选项说的是香料可以用来买香水和药,不是一个意思啊,为什么选第三个选项?

我对第三个选项的理解是：
spices could be traded 是指香料从亚洲被买到了欧洲,
for products such as perfumes and medicines是指欧洲人买来香料之后是为了得到类似于perfumes and medicines的产品（products）————也就是说,欧洲人买来了香料,然后用它做出perfumes、medicines之类的产品,这与文章中的关键词manufacture相符合.
下面分析其它选项：
A：文中只是说But even high-priced commodities like spices had to be transported in large bulk,是不得不这样运输,而不是这样运输很容易,两者无必然关系.
B：文章没有提及
D：文章没有提及
