With corn, soybean, and wheat reserves being low enough so a poor harvest would send prices skyrocketing, grain futures brokers and their clients are especially interested in weather that could affect crops.
being low enough so
so low such that
so low that
that are low enough so
that are so low such that
enough和so不应连用
so…that和such…that均为正确的表达方式,但是so…such…that是不正确
由于原文中整个句子是以一个独立主格开头的(with),且本选项中该独立主格中没有分词(也没有形容词,只有一个定语从句),所以该选项不满足构成独立主格结构的要求(独立主格不能由定语从句构成)
