🔍 Key Concepts

• Compare the overall shape of the cooler (round shell vs. stacked plates). • Look closely at the flow paths for oil and water shown by the arrows inside the unit. • Decide whether the labels (oil inlet/outlet, water inlet/outlet, vent and drain) are describing a type of construction or just features of operation.

💭 Think About

• From the cutaway view, what kind of internal elements actually carry the oil – many small tubes, flat plates, or something else? • Which answer choices describe a basic cooler design, and which sound more like a special feature or arrangement that any cooler type might have? • If you removed the end covers, what removable part would you expect to pull out of this unit based on the picture?

✅ Before You Answer

• Confirm whether you see a cylindrical shell with a bundle of tubes or a stack of flat plates. • Check if any option is just an operational characteristic (like how air is vented) rather than a physical construction type. • Make sure the choice you pick clearly matches the internal geometry shown in the cutaway, not just the external fittings.
