Answer:
E. Had Bergeron also fulfilled the financial disclosure requirements for candidacy before any previous gubernatorial elections?
Step-by-step explanation:
Taking into consideration that this is one of the requirements to become a candidate for governor and the journalist found it pertinent to mention Arnold Bergeron's doing it, it is highly possible that he has not fulfilled these requirements yet. So, determining whether he had done this in the past will make his hypothesis gain or lose support.
