This figure shows six studies that have determine the association between air pollution concentration in a major city and risk for morbidity & mortality.

Solution

3: the criteria that this figure represents is the dose-response relationship.

it could be seen that as we increase the dose of the fungicide,. the disease % goes down. since the recommended dose of the fungicide is 1, the disease reached almost 0% prevalence at 1 dose. therefore it is the dose response relationship.
