这句中介词in起什么作用,不可以只用which引到一个定语从句吗?

i knew that even if the case was one in which it was impossible to anticipate the problem in advance,i could handle whatever i found

<even if the case was one (in which it was impossible to anticipate the problem in advance)>,i could handle (whatever i found))
1,that 引导的宾语从句!2,which 引导的定语从句!which 相当于the case 调整过来就是<in the case >it was impossible to anticipate the problem in advance.因为case 在词句中加in 做的是状语!所以要用in !如果不用in ,或者其他的介词!那么which所代表的中心词就在它所引导的从句中作个必要成分:宾语!3,whatever i found从句做的是handle的宾语!whatever 在从句whatever i found中作found的宾语!4,整个句子如果省掉一些修饰的从句,本质意思就是i knew i could handle somthing 也就是whatever i found。
剩余的都是修饰成分,表达更具体更详细一些!

必须要用in
in which代替的是in the case
不用定语从句的话就是in the case it was impossible to anticipate the problem in advance

in的作用是in which=where,
可以用which引导定语从句,但这里不行,因为where是关系副词,which是关系代词,不能随便替换

首先有个短语in the case
which指代的就是the case
所以加上in
