A recent study monitored the blood pressure of people petting domestic animals in the laboratory. The blood pressure of some of these people lowered while petting the animals. Ttherefore, for any one of the people so affected, owning a pet would result in that person having a lower average blood pressure. The flawed pattern of reasoning in the argument above is most similar to that in which one of the following? ['Since riding in a boat for a few minutes is relaxing for some people, those people would be more relaxed generally if those people owned boats.', 'Since pruning houseplants is enjoyable for some people, those people should get rid of houseplants that do not require frequent pruning.', 'Because buying an automobile is very expensive, people should hold on to an automobile, once bought, for as long as it can be maintained in running condition.', 'Since giving a fence one coat of white paint makes the fence white, giving it two coats of white paint would make it even whiter.']
