Passage Summary: Two officials are debating a new power plant. One says they have to pick the cheapest option for the public, but the other says the pollution from that cheap option makes it a terrible choice.

Conclusion: Councilperson X believes the council must endorse the lowest-rate design, while Councilperson Y believes they should not because of environmental costs.

Reasoning: X argues the council's obligation is to ensure the lowest rates possible, whereas Y argues that the obligation to protect air quality and quality of life is more important than lower rates.

Analysis: Councilperson X is a bit of a one-track mind, focusing entirely on the bottom line of electricity rates. Councilperson Y, however, introduces a 'big picture' perspective, arguing that saving a few bucks isn't worth choking on smog. To find the point at issue, look for the specific claim that one person says 'yes' to and the other says 'no' to. Here, they disagree on whether the specific design that yields the lowest rates is the one that must be endorsed.
