Randy: After Mega Cable Television Company refused to carry the competing Azco News Service alongside its own news channels, the mayor used her influence to get Azco time on a community channel, demonstrating her concern for keeping a diversity of news programming in the city.
Evidence
After Mega Cable Television Company refused to carry the competing Azco News Service alongside its own news channels, the mayor used her influence to get Azco time on a community channel.
Conclusion
The mayor's action is rewarding Azco's owner, a political supporter of hers.
Evaluate
Marion speculates a reason (rewarding a political supporter) for the mayor’s action (using influence to get Azco News Service time on a community channel). To weaken this argument an answer could provide an alternative reason, identify a supporter who was not provided some benefit, or identify someone who received a similar benefit who was not a political supporter.
