🔍 Key Concepts

• Identify where M is located in relation to the disc stack (top, middle, or bottom) • Recall the function and location of a paring disk in a centrifugal purifier • Notice how the discs are arranged inside the bowl and which ones actually separate the liquid phases

💭 Think About

• Is label M pointing to a single special component, or to one of many similar plates that make up the stack? • Does the part at M appear to be at the very top, the very bottom, or somewhere in between the disc stack? • Which option describes a component that is unique in shape or function compared to the rest of the stack?

✅ Before You Answer

• Confirm whether M is part of the stack of many thin conical discs or a separate, unique part • Check if the part at M is at the upper end of the disc stack, the lower end, or in the middle • Verify what the paring disk normally looks like and where it is mounted in a purifier bowl
