A woman has complained to the authorities about the health standards of a certain restaurant. The woman was hospitalized shortly after leaving the restaurant where she had eaten a meat dish, followed by a dessert dish. When questioned, no one else that had eaten at the restaurant that day reported illness of any kind. This data clearly suggests that the woman is accusing the restaurant falsely.
Which of the following would it be most useful to establish in order to evaluate the argument?
A. Whether any of the diners to the restaurant that day had eaten either one of the dishes the woman had ordered
B. Whether the woman has complained about a company's service, or product, in the past
C. Whether the meat used by the restaurant was chicken or beef
D. Whether the woman can be held responsible for any negative publicity caused by the accusations
E. Whether there is enough public interest for the authorities to launch an in-depth investigation into the case
