求助一道GWD题！！

A shortage of orders for Manto Aircraft's airliners has led analysts to predict that
the manufacturer will have to lay workers ,the new order that consolidated
airlines 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 new
order , consolidated canceled its existing order for an equal number of manto's
larger, more expensive model Z jets

which of the following ,if true, most seriously weakens the argument?
 
 Manto relies more heavily on outside subcontractors to provide the labor to manufacture the Model Z than it does the Model TX  
 
 The Manto employees who currently work to manufacture the model Z are Not proficient at manufacturing the model TX  
 
 Manto includes all required maintenance work for the first five years in the price of each jet it sells .  
 
 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  
 
 A large number of the airliners in consolidated is fleet are at the beginning of their expected service life  

这题的正确答案到底是A还是E呢？？

个人认为是A，GWD说的是E，我觉得比较牵强。原因如下：
前提：1、M公司的订单太少；
         2、虽然受到了T订单，但同时也失去了相同数量的Z订单

因此：M公司还是会裁员。

驳斥：倒推整个过程，如果要裁员，就是表示不需要那么多工人。怎么会导致不需要这么多工人呢？
A：生产Z引擎都是外包的，生产T的不是。也就是说，如果本来生产同样的Z引擎要的工人要比生产同样的T引擎需要的工人少。也就是说，这个心的订单会导致需求的工人比现阶段增加。那怎么会导致裁员呢，可以驳斥。
E：很多飞机刚开始服役。这个都已经卖出去了，跟M公司没有关系了，难道是售后服务？文章没有这么说

所以，A好点
