Task: Answer the proper and disfluent questions based on the given context, or return None if an answer can't be found.

Proper question: What did the Rhine branch off to form in Austria?
Disfluent question: What delimits oh uh what did the Rhine branch off to form in Austria?

Context:
The mouth of the Rhine into Lake Constance forms an inland delta. The delta is delimited in the West by the Alter Rhein (Old Rhine) and in the East by a modern canalized section. Most of the delta is a nature reserve and bird sanctuary. It includes the Austrian towns of Gaißau, Höchst and Fußach. The natural Rhine originally branched into at least two arms and formed small islands by precipitating sediments. In the local Alemannic dialect, the singular is pronounced Isel and this is also the local pronunciation of Esel (Donkey). Many local fields have an official name containing this element.

Solution:

For the proper question, we can find the answer directly from the context:
"The natural Rhine originally branched into at least two arms and formed small islands by precipitating sediments."
Answer: The Rhine branched off to form small islands in Austria.

For the disfluent question, we first need to identify the proper question within it:
"What delimits oh uh what did the Rhine branch off to form in Austria?"
The proper question is: "What did the Rhine branch off to form in Austria?"
We have already found the answer for this question above.
Answer: The Rhine branched off to form small islands in Austria.

Output:
