Could someone take a stab at diagramming this? Is this prompt even amenable to diagramming?

This seems like a very weird way to go about strengthening an argument. I feel like it depends too heavily on the test taker thinking of the right alternative hypothesis to discredit so that they can identify the corresponding piece of evidence that contradicts it. Why not cut to the chase and ask yourself which answer choice makes the conclusion more likely to be more, similar to an MSS question?

Re: D, why isn't it possible that the price could've doubled without the speed/transistors doubling? Couldn't there have been other reasons, at intervals other than 18 months?

For Q3, I would've translated the embedded conditional as:

/NEA --> (OC --> PMPO)

If using the Domain + Rule technique, why is the domain not found by taking the outside sufficient condition (i.e., D: /NEA)?
