2. the restaurant company has recently added many new restaurants across the country and its sales increased dramatically, its
3. many new restaurants have recently been opened across the country and its sales increased dramatically, the restaurant company’s
4. having recently added many new restaurants across the country and with its sales increasing dramatically, the restaurant company’s
5. recently adding many new restaurants across the country and having its sales increase dramatically, the restaurant company’s

答案是A，

本题有讨论的，但是没有我想知道的这个问题，不是问答案正确与否，是有关于it和its指代的疑问：

1，its到底是指代单数还是复数，如题A答案，是指代the restaurant company 还是指代many new restaurants ，

2，不管指代哪个，代入代词后是the restaurant company sales或many new restaurants sales，

    个人感觉应该是the restaurant company ’s  sales或many new restaurants’ sales才是正确的啊

    这样its sales是不是就表达不准确了呢

3，its如果指代单数，为什么不用it，如果后面加sales，为什么不是it’s    sales啊。

4，同理，its指代复数的话，加sales，应该是its’ sales吧。

请明白人指导，万分感激！
