Say we have the following sentence :
The further information I need is to know in which building is the class held.
Is it grammatically correct to place "is" where it's placed in the sentence, or should it be moved after the word "class", like this:
...in which building the class is held.
The sentence isn't interrogative, so my guess is the second variant is fine, but sometimes I become quite dubious(this time, for example).
