If the play were successful, it would be adapted as a movie or revived at the Decade Festival.
Conclusion
The play won't become a movie nor will it be revived at the Decade Festival.
Evidence
If the play were successful, it would become a movie or get revived at the Festival. But, it is not successful.
Evaluation
Whenever we see any conditional logic ("If") on a Flaw question, we should immediately be on the lookout for whether the author commits a Necessary vs. Sufficient flaw by reasoning in a backwards or opposite fashion.
The author provided this conditional, successful → adapted or revived
Then proceeded to argue that SINCE successful, adapted and revived
If we're given A → B or C we can't infer ~A → ~B and ~C
Goal
Look for an answer calling out the Necessary vs. Sufficient flaw or one that conversationally explains that there might be more than one possible route to getting adapted or revived (yes, being a successful play is one way, but maybe being a play that is beloved by a famous actor is another way)
