Given the task definition, example input & output, solve the new input case.
The goal of this task is to translate questions in English into Catalan. The requirements of the translation is that: the text must be equivalent in meaning, the text must not be ambiguous, and the text must be written as a question
Example: How many points did the Panthers defense surrender?
Output: Quants punts va cedir la defensa dels Panthers?
This is a good translation, because the translation conveys the same meaning and is not ambiguous.

New input case for you: Whose principles were the principle of faunal succession built upon?
Output:
Com esdevé el principi pel fet que no tots els fòssils es puguin trobar alhora arreu del món?
