Although the sanitary inspection procedures for banquet establishments are much stricter than those of ordinary restaurants, in the cases of food poisoning reported to the municipal health department, there are still more banquet services than ordinary restaurants. Which of the following options is true and can best explain the apparent contradiction in the problem stem? ['People are unlikely to make a connection between a meal and the illness that follows, unless the illness affects an interconnected group.', 'The organization hosting the banquet clearly knows how many people they will serve, so it is less likely than regular restaurants to have leftover food, which is a major source of food poisoning.', 'Many restaurants provide personal catering services as well as catering services.', 'The number of reported cases of food poisoning during the banquet has nothing to do with the services provided by the banquet host and customers.']
