Although the fact is that the sanitary inspection procedures for the institution preparing the banquet are much stricter than the procedures for ordinary restaurants, in the case of food poisoning reported to the municipal health department, the banquet services are more than ordinary restaurants. Which of the following options best explains the above phenomenon? ['At any time, more people eat at the restaurant than at the banquet.', 'It is unlikely that people will establish a link between a meal and the illness that follows, unless the illness affects an interconnected group.', 'The number of food poisoning cases reported at the banquet has nothing to do with the nature of the service establishment.', 'The organization that prepares the banquet knows how many people they are serving, so it is less likely to leave food than the ordinary restaurants-a major cause of food poisoning.']
