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?

I sort of get that the word "accompanied" is doing a lot of the heavy lifting here, but when JY draws the bi-conditional it destroys my understanding of the relationship.

Can someone explain how the distribution of the "not" symbol is working here?

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)?
