5. By applying optimization techniques commonly used to plan operations, it is possible to determine how much effort ought to be devoted to each of a company’s products in order to meet its goals in both the short and long terms.

• it is possible to determine how much effort ought to be devoted to each of a company’s products in order to meet its goals in both the short and long terms
• a company’s managers can determine how much effort should be dedicated to each of the company’s products in order to meet its short and long term goals
• it can be determined by company managers how much effort ought to be devoted to each of the company’s products in order to meet its goals, both short and long term
• it may be possible for company managers to determine how much effort should be dedicated to each of these products in order to meet the company’s short and long term goals
• managers at a company can determine how much effort ought to be dedicated to each of these products in order to meet the company’s goals in both the short and long term
这题答案选择B；我想请问牛牛们，B里的its指代的是什么？如果指代的是company，可是这个句子里company是形容词形式，不是不可以被指代的么？还是说指代的是a company' managers ?如果是指代公司经理的话，its可以指代人么？

还是说，B里的its指代的确是不对的，但是和E比起来，E更糟糕，所以选B？

谢谢~~~

1. 正确选项里的语法肯定是对的, 只要是出自可信的来源.

2. its只能指a company's，因为:
a. its不能指人
b. a company's 不是形容词, 是名词所有格, 是带着"‘s"词尾来表示所有关系的名词
c. 所有格代词指代名词所有格, 只要单复数相符, 句意相符, 一般都不会产生语法错误.
