Political theorist: Newly enacted laws need a period of immunity during which they can be repealed only if circumstances are dire.
Conclusion
A newly acted law should be immune from repeal for a while, unless things are dire.
Evidence
In the short-term, a new law is likely to be painful, while the long-term benefits are initially obscure because it takes a while for people to learn how to use the law to their benefit.
Evaluate
Normally with Strengthen + Principle question, we anticipate a possible answer by saying, "If evidence, then conclusion". It seems hard to do that here.
We still want to focus a lot of energy on what the Conclusion is trying to prove. It wants a period of immunity for new laws, so that they can't be quickly repealed.
Why? Because at first the law might hurt, but in the long-term it might be for the better, so we need this period of immunity to force us to "stick it out" through the initial rough period.
When a Principle question's evidence contains a good thing and a bad thing, (we call it Weighing Tradeoffs in the Question Feature menu), we often are just looking for a strengthener that tells us which of those is more important.
Goal
Look for something that sounds like, .
