Newscaster: In order for the public to participate in a meaningful way in the current public policy debate, one requirement is that the issues be stated in terms the public can understand.
Conclusion (so)
The public might be able to participate in a meaningful way in the current public policy debate.
Evidence
For the public to participate in a meaningful way in the current public policy debate, the issues must be stated in terms the public can understand.
The mayor's speech just stated these issues in a way that the public can understand.
Evaluate
This is a reasonable, if not valid argument.
We see a lot of repeated language, so this would be a good contender to diagram into abstract variables.
We have a conditional premise, that provides a requirement:
A → B
We have a factual premise, "The mayor stated the issues understandably", which establishes that the requirement has been met.
B.
And then we conclude with very weak language that the sufficient condition might still happen, "We might have meaningful participation".
A is possible.
If a necessary condition hadn't been true, it would prove the sufficient condition isn't true. By establishing that a necessary condition is true, we're only establishing that the sufficient condition is still possible.
Goal
Let's look for something like P1: A requires B. P2: B is true. C: thus, A might be true.
