请教几道关于托业的题目，求热心的大侠们一定帮忙解答，小的跪谢了！！

Question

we will take whatever action is needed to simplify the decision-making process and increase efficiency.请问这里action之后的is needed to是什么用法？will take 和is needed to有两个谓语，真的不是很理解，求大侠帮忙解答一下好吗。

upon permanent relocation company will allow additional relocation assistance to be mutual agreeded upon within the parameter we have discussed during your visit.
这里的to be mutual agreeded 怎么理解？意思我都知道，但在结构和语法上我不太理解。
upon within在这里的用法我也不太理解，求大侠解说。

Answer 1

is needed to做定语修饰action。这是个宾语从句。whatever action is needed to simplify the decision-making process and increase efficiency是一个完整的句子。take才是这个句子的大宾语。

追问

宾语从句前面不是要有连接代词嘛？

追答

take后面省略了that
