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.
老师好，请问这一题在讲义哪里说了？看前面的回答现在的讲义是不是删除了相关内容？商品期货在实物交割之前是否都会由short方issue a notice of intention？如果short方故意以次充好，是否同样会导致交割失败？谢谢
