82一道是说有个制造企业生产出一种洗衣粉，里面有一种酶可以分解衣服的颜色，使衣服的洗完以后和原来一部分褪掉的颜色一样。后来这个产品成功了，问支持。有两个选项有点搞的，我选了能生产出不一样的效果的产品容易成功。还有一个是关于酶和衣服怎么样的，好象是E，没看很明白。
还有一题是飞机制造企业接了个什么定单。但是接了新的定单还是没赚到钱，这道题目我觉得我做过，可能在GWD里。
果然被我找到了~~对，就是这个，不过我忘了我选了什么。。。(640)
A shortage of orders for Manto Aircrafts airliners has led analysts to predict that the manufacturer will have to lay off workers, the new order that consolidatedairlines has just made for 20 of Manto’s model TX jets does not provide a reason for the analysts to revise their predictions, because simultaneously with its neworder, consolidated canceled its existing order for an equal number of manto’slarger, more expensive model Z jets.

Which of the following, if true, most seriously weakens the argument?

A.Manto relies more heavily on outside subcontractors to provide the labor to manufacture the model Z than it does the model TX

B.The Manto employees who currently work to manufacture the model Z are not proficient at manufacturing the model TX

C.Manto includes all required maintenance work for the first five years in the price of each jet it sells

D.Manto has had to lay off workers several times within the past ten years but has typically rehired many of the workers when it subsequently received new orders

E.A large number of the airliners in consolidated fleet are at the beginning of their expected service life
