Oscar: Emerging information technologies will soon make speed of information processing the single most important factor in the creation of individual, corporate, and national wealth.
Conclusion (thus)
The new technologies will widen the existing economic gap between north and south.
Evidence
The poor southern countries lack the resources to acquire the new technologies and will therefore remain poor.
Evaluate
Sylvia establishes that the south will not be able to use these new technologies to increase their economic wealth.
But for a gap to widen, that would mean that the north DOES increase its wealth, via these new technologies.
So she must be Assuming a Difference. She explicitly states that the south doesn't have the resources to acquire these new technologies, but she must be implicitly assuming that some countries in the north do have the resources to implement them.
We could also potentially argue that as a result of these new technologies, other components of the world's economy will change in ways that would hurt the north or benefit the south.
Goal
Let's look for an answer that spells out the Assumed Difference (that the north will be able to capitalize on the new tech) or one that rules out a potential objection (that in this new tech world, some other thing would change that benefits the south or hurts the north economically).
