Beverage company representative: The plastic rings that hold six‐packs of beverage cans together pose a threat to wild animals, which often become entangled in the discarded rings and suffocate as a result.
Conclusion (therefore)
The threat of suffocation that plastic rings pose to wild animals will be eliminated once all beverage companies complete the switchover from the old to the new plastic rings.
Evidence
The plastic rings that hold six-packs of beverage cans together pose a threat to wild animals because these animals often become entangled in the discarded rings and suffocate.
All beverage companies will soon use rings made of a new plastic that disintegrates after three days of exposure to sunlight.
Evaluate
This argument presents a Plan / Goal structure:
Plan: Switchover from old plastic rings to new plastic rings that disintegrate quickly.
Goal: Eliminate the threat of suffocation that plastic rings pose to wild animals.
How could we potentially follow this Plan but fail to achieve the Goal? All the companies have switched to the new plastic rings, but there is still some threat of suffocation posed by plastic rings..
Maybe the new plastic rings are suffocating the animals before they disintegrated (like on day 1 or day 2 of sunlight). Maybe some of the new plastic rings end up in the shade where they never receive sunlight and thus don't disintegrate.
Goal
Let's find an answer that allows us to say that even if we follow this Plan, we will still have some threat of suffocation posed by plastic rings..
