🔍 Key Concepts

• Carefully match the frame numbers on the scale at the bottom of the illustration with the location described (frame 127). • Distinguish between upper engine room and lower engine room on the diagram, then focus only on the portside of the lower level. • Identify the machinery symbols and labels in that exact small area and compare them with the wording of the answer choices.

💭 Think About

• On the lower half of the drawing, which side is port and how can you tell? Once you know that, where exactly does frame 127 fall between the marked frame numbers on the scale? • At frame 127 on the lower portside, what specific symbol(s) and text labels are shown there, and which of the answer choices best matches that label? • Are there any nearby labels (like CO₂ station numbers or pump numbers) that might distract you from the main piece of machinery at that location? How can you separate those from the machinery being asked about?

✅ Before You Answer

• Confirm you are on the lower engine room portion of the drawing (not the upper). • Confirm you are on the portside of the centerline and lined up with frame 127 using the frame scale. • Read the exact label next to the machinery symbol at that location and match that wording to the closest answer choice.
