Question stem: In the past, Smith was opposed to building nuclear power plants. However, Smith then changed their mind, and now they are in favor of such plants. Therefore, we should build nuclear power plants.
Flaw: We don't get an actual argument relating to nuclear power plants themselves. All we get is an appeal to Smith's supposed authority on the matter, but why should we listen to them? Clearly, we'd like to hear some more substantial argumentation relating to the pros and cons of nuclear power itself, not just an appeal to some individual's opinion. Answer choice (E) picks up on this and underscores the need for a genuine argument.
