People who have spent a lot of time in contact with animals often develop animal-induced allergies, some of them quite serious. In a survey of current

population who have spent a similarly large amount of time in close contact with animals, the percentage with animal-induced allergies is not 30 percent
but substantially more.
 
Which of the following, if true, provides the strongest grounds for the experts' conclusion?
