(AA131)快考了，急问ＡＡ１３１！！

131. The following appeared in a memorandum from the human resources department of HomeStyle, a house remodeling business.
“This year, despite HomeStyle’s move to new office space, we have seen a decline in both company morale and productivity, and a corresponding increase in administrative costs. To rectify these problems, we should begin using a newly developed software package for performance appraisal and feedback. Managers will save time by simply choosing comments from a preexisting list; then the software will automatically generate feedback for the employee. The Human Resources department at CounterBalance, the manufacturer of the countertops we install, reports satisfaction with the package.”

错误:1The decline of the morale and productivity can simply be the result of the move, thus making the proposal to use a newly developed software package useless.
2The software package seems not able to solve new problems out of the preexisting list.
3The manufacturer will apparently report satisfaction with its own products.
4The author commits a fallacy of false analogy.

这里怎么有错误类比？？没有看出来，请高人指点～！！！还有第三点没怎么搞懂．
