in the section “Policymakers of the Future,” the author says “the anger between liberals and conservatives seems to have reached unsustainable levels.” Does the author support this claim with sufficient evidence? Explain.

To appropriately respond to whether the author supports the claim with sufficient evidence, we would need to examine the text in the section “Policymakers of the Future.” It is crucial to look for and analyze the evidence provided by the author that indicates the anger between liberals and conservatives is at unsustainable levels. Depending on the content of the text, here's how you would determine if the evidence is sufficient:

1. Type of Evidence: Does the author use statistical data, historical examples, results from studies or surveys, expert opinions, or anecdotal evidence? Sufficient evidence would ideally include hard data or authoritative testimonials that demonstrate the extent of anger and its implications.

2. Relevancy of Evidence: Is the evidence presented directly relevant to the claim about the level of anger between the two political groups? It should clearly relate to instances of friction, confrontation, or breakdown in communication that reflects unsustainable levels of anger.

3. Adequacy of Evidence: Is there enough evidence provided to convincingly attest to the unsustainability of the anger? There should be more than just one or two examples; a broad range of evidence from various sources or contexts would strengthen the claim.

4. Analysis and Interpretation: Does the author explain how the evidence connects to the claim and why it proves the level of anger to be unsustainable? The evidence should be accompanied by analysis that uncovers the underlying reasons for the anger and how it affects policymaking and social relationships.

5. Counterarguments: Does the author address potential counterarguments or different perspectives? A strong argument typically recognizes opposing views and provides a rationale as to why the presented evidence is more compelling.

If the author presents thorough, relevant, and adequately analyzed evidence without disregarding significant counterarguments, then we can conclude that the claim is supported with sufficient evidence.
