急！请教，Argument B3和B6的主要攻击点……

请教，Argument B3的主要攻击点是什么啊？

最后那句increase our firm's profit margins看得很晕~~

B3. The more efficient a firm’s employees are, the more profitable that firm will be. Improvements in a firm’s information technology hardware and software are a proven way to increase the efficiency of employees who do the majority of their work on computers. Therefore, if our firm invests in the most powerful and advanced information technology available, employee productivity will be maximized. This strategy ensures that every dollar spent on enhanced information technology will help to increase our firm’s profit margins.”

还有B6“Commercial real estate prices have been rising steadily in the Sandida Heights neighborhood for several years, while the prices in the adjacent neighborhood of Palm Grove have remained the same. It seems obvious, then, that a retail space in Sandida
                        Heights must now be much more expensive than a similar space in Palm Grove, which was not the case several years ago. So, it appears that retail spaces in Sandida
                        Heights are now overpriced relative to those in Palm Grove. Therefore, it would be in our financial interest to purchase a retail space in Palm Grove rather than in Sandida
                            Heights.”

是否考虑买这个retail space是为了投资房产，还是自己经营衣服生意这点？

希望牛人帮帮忙，没几天就考了，急啊！

万分感谢！！

1、more efficient employee→more profitable 企业盈利的变量有很多。比如技术垄断，现金流，周转率，行业等

2、第二句话：improvements只能提高机器的效率，人的效率主要在思维或者使用电脑的技术，机器本身所带来的提高比例很小。（还有机器提高所需的成本于收益比较）

3、第三剧：a、 公司的支出项目很多，在IT上投资是不是最必要的？

                     b、 most powerful and advanced 过于先进，超出实际需求

                     c、 在IT上投资真的会提高员工efficiency？这个有太多可以讲了。

                     d、 profit margin就是利润边际，比方说，一个东西成本6元，卖10元

                           profit margin就是10 - 6＝4元

我不是牛

但希望能有帮助
