Passage Summary: Phone companies are about to offer way more TV channels for the same price as cable, so cable is probably going to go out of business soon.

Conclusion: Telephone companies will likely replace cable companies as the primary television providers within a few years.

Reasoning: Telephone companies will soon use fiber-optic technology to offer significantly more channels than cable companies for the exact same price.

Analysis: The argument assumes that 'more channels for the same price' is the deciding factor for consumers and that cable companies won't be able to upgrade their own tech in time to compete. To strengthen this, we should look for an answer that confirms consumers actually value a high number of channels or suggests that cable companies are stuck with their current 50-channel limit. If people only watch five channels anyway, the phone company's 150-channel advantage might not be the 'cable-killer' the author thinks it is. Look for something that solidifies the competitive advantage of the fiber-optic offering.
