   Out of Scope: not wanting a dog This argument is only about the people in the conclusion, who are apartment dwellers who have limited time to give a dog exercise but who want to have a dog. The author doesn't have to assume anything about other people / other situations.

   Why this is right

   The author was definitely Assuming a Difference, when it came to large dogs and small dogs. He thought that an apartment dweller with limited time would have an easier time exercising a large dog to its needed intensity than they would exercising a small dog to its needed intensity (which is higher than that of a large dog). So if the author thinks that we'll have a harder time exercising the dog that requires more intensive exercise, he must be thinking that dogs who require more intensive exercise require more time to exercise than do dogs with lower exercise intensity needs. If we negate this, and it says, "Providing the more-intense dog with adequate exercise does not require any more time", then it would be a huge objection. It would destroy the assumed difference between how things would go with "apartment + limited time + large dog" vs. "apartment + limited time + small dog".

   Skill tested: Necessary Assumption · how this choice captures the argument's function is the move to repeat next time.

   The author isn't saying anything normative that would allow us to derive her assumptions on what should be the case. She's just describing what is. Also, this sentiment does not sound like her. She is offering advice for what people w/ limited time, in an apartment, should do if they want a dog (get a large one!)

   We only talked about apartments in one categorical way. We can't divide up that category into large apartments and small apartments and pretend like the author had a clear position on that split.

   This answer shouldn't be appealing to us, in the sense that it is lost in the language of the first sentence, which was a premise. We're being tested on what is assumed as the author moves from Premise to Conclusion. We're not being tested on the internal logic of something said in the Premise. The paragraph talks about exercising your dog at the right intensity in order to stay fit. It doesn't talk about the frequency with which you give your dog exercise, so that concept is also out of scope.
