Your question is Shut Down or Fix a Faulty Line. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
If you knew there was a line producing parts that was creating faulty parts but you had a part change coming soon, would you keep running the line and just wait for the change or would you shut down the line and find the issue?
