Philosopher: Groups are not the type of entity that can be worthy of praise or blame.
Main Conclusion
If you're trying to praise or blame a group, you need to cast that statement in terms of individuals, if we're gonna properly evaluate your claim.
Intermediate Conclusion
Groups are not a type of entity that you can praise or blame.
Evidence
Blaming something requires that the thing has conscience and agency (an ability to decide for themselves).
Nations don't have consciences. Families are not agents.
Evaluate
On Role questions, it's unusual for the last claim of the paragraph to be the Main Conclusion (only about 10% of the time), but we know it's a conclusion from the fact that it's prefaced by Hence.
On Role questions, it's very common for the first claim of the paragraph to be the Main Conclusion, and the first claim of this paragraph is a conclusion, since we immediately start unpacking / supporting it with the 2nd and 3rd sentences.
To figure out the relationship between those two conclusions (the first and last claim) we can use the Support Test. Which one would be a supporting idea for the other?
why should we believe that groups aren't the sort of entity you can praise/blame?
why should we believe that if we want to praise or blame a group, we have to translate that into a statement about individuals, or else we can't evaluate it properly?
When we ask the 2nd question, the 1st claim actually sounds like Support.
Why should we re-cast praise or blame about a group into statements about individuals? Because, groups aren't the sort of entity you can praise or blame.
This is how we know the first claim is subordinate to the last claim.
Goal
We're being asked about the 3rd sentence, which was a premise. If we wanted to get more specific, it was a premise helping to support the Intermediate Conclusion.
