is 為何擺係句尾

Referring to Noun Clause:-
Subject+verb+preposition+object of preposition
Re:-Subject+verb+object:-
eg:-We could not decide on where we are(=she is)
-----The preposition "on" can be omitted.Any object-word omitted should be added by your goodself.The sentence could be re-written:-The generator room is flooded.(to what degree?)
eg:-New immigrant could not decide on where she is.
eg:-What nationality do you think she is?
eg:-What do you think she is?
eg:-Hence:-How flooded do you think the generator room is?(=noun clause as object as an attempt to answer only with other similar examples)

What nationality do you think she is? ~ wrong
You can't answer in this way ~ "She is French nationality".

What nationality do you think she has?
She has French nationality.

Nationality is the state of being legally a citizen of a particular nation, (~ not a citizen)

What do you think is? ~ wrong,
~ missing the subject of the linking verb "is"

What do you think she is?
What do you think he is?

How flooded do you think the generator room is?
The generator room is flooded beyond repair.

Passive voice ".. is flooded ." 是需要 auxiliary verb "is"

How shocked do you think he is?
He is shocked beyond description

例子 is 放在句尾
I become increasingly aware of how beautiful she is.

How flooded do you think the generator room is?
可參考這個例子:what do you think is﹖

後面只不過省略了未知的句字﹖

Who do you think I am?

How old do you think she is?

What kind of people do you think they are?
