第一道：
Increase不可数，不能用many修饰

第二道：
They were 没有并列对象

第一道LS已经说清楚了，第二道B的比较不对称，应该是to be和they have been对称

补充第一道，1. twice as many as 做appositive modifier.最好紧跟其修饰词，即，最好前面是数字
2. 根据manhattan，如果noun in question is already an explicitly numerical quantitiy, much或者many都不要用。直接用twice或者double.
EG: twice as much water
twice the water 错，water不可数，需要加上much
twice as much as the increase 错 increase是explictly numerical quantity
twice the increase 对
