Cevap
The City Treasurer commits a conditional reasoning flaw, the Political Commentator makes an ad hominem (source) argument, the Arts Critic commits a flaw of composition, and the Nutritionist confuses correlation with causation.

The Political Commentator's argument is an ad hominem attack focusing on motives. The Arts Critic's argument represents the fallacy of composition (part-to-whole). The Nutritionist's argument confuses a correlation with causation.
