Claims of Policy or Solutions
Claims of policy or solutions propose and promote policies and solutions based on changing an existing policy that is either inadequate for dealing with a bad situation or conducive to its perpetuation. For example, "Football causes too many injuries and ought to be banned."
Arguing such a claim may require arguing a combination of claims and several steps might be involved: A factual claim establishing that a situation exists, a value claim proving the situation is bad, and a cause and effect claim pinning the blame on a policy that, if changed, will improve the situation may all play a role in the overall argument.
Be advised that proposing a solution carries the inherent suggestion that more than one solution may apply. An argument successfully advocating your position must establish the criteria by which all solutions will be measured and prove that yours meets that criteria better than any other.
