The timing of peanuts' first introduction in children's diet could affect allergic reactions, so physicians have debated whether to recommend early exposure or avoidance. A study enrolled 640 infants with severe eczema and split them into two groups based on whether they also had a diagnosed peanut allergy. Within each group, the researchers randomly assigned the infants to either completely avoid peanuts or consume peanuts in small amounts regularly until they reached 60 months of age. At the end of the study, an allergy test was conducted to establish which children had a peanut allergy. (a) What are the individuals, the treatments, and the response variable in this experiment?
