问题如下：
Several different grades of corn can be delivered in a futures contract. Can the party with a long position who has entered into a particular contract specify which grade it wants?
选项：
解释：
No. Traders with short positions choose what will be delivered. When issuing a notice of intention, a trader with a short position specifies which grade will be delivered.
不是很明白，讲义120页写的exchange stipulates the acceptable quality of good 我理解的是long/short在进入期货合约时就已经知道具体交割的品类，不知道这样理解是否正确。

请问这道题目的gra表示的是什么呢，合约制定的时候没有标明种类嘛?不太理解可以具体说明一下合约制定的时候什么是定好的和没定的嘛
老师请一下讲义120页中 failure the exchange to aquately stinguish gras of the unrlying asset coulcause the contrato fail? 与这道题中提的gras的意思
