Answer:
This argument is an example of:
A. logical appeal (logos).
Explanation:
Logos is a type of rhetorical appeal that uses logic to convince the audience of something. For that reason, logos relies heavily on evidence, such as data and statistics. The speaker or writer's purpose is to walk the audience through the claim and the evidence (from point A to point B and so on) until they reach the same conclusion.
The argument we are analyzing here is an example of logos. The writer wants his audience to conclude that dogs are the best type of pet. He defends that claim by stating that dogs go for walks. To support that, he offers evidence by citing statistics that prove dog owners are more active.
