Passage Summary: Because new digital news services are faster and more tailored to what people want than old-school newspapers, the author predicts that newspapers are going to lose a ton of customers.

Conclusion: Newspaper sales will drop significantly if personalized electronic news services become widely available.

Reasoning: Electronic news services provide updated information on specific topics faster and more efficiently than printed newspapers can.

Analysis: The argument relies on the assumption that speed and efficiency are the primary drivers of newspaper consumption. To weaken this, we need to find a reason why consumers would continue to buy printed newspapers despite the digital competition. Perhaps there are unique benefits to print, such as portability, lack of screen strain, or specific content not found online. If people value these non-efficiency factors, the predicted 'drastic decline' in sales might be overstated.
