🔍 Key Concepts

• Identify which component in the illustration is the pinion gear (the smaller gear that meshes with a larger gear). • Notice the labeled shafts: #1 and #3 are aligned on the upper shaft, while #2 is on the lower shaft and #4 is on the right side of the housing. • Think about whether "between" refers to along the same shaft horizontally or vertically between upper and lower shafts.

💭 Think About

• First, locate the large bull gear on the lower shaft and then find the smaller gear that meshes with it. Where is that small gear positioned relative to the numbered points? • Ask yourself: does the pinion lie along the upper shaft between its two ends, or is it located more in line with the lower shaft and right-side housing? • Look carefully at how the upper shaft runs from #1 to #3. Where, along that path, is the small gear mounted?

✅ Before You Answer

• Be sure you can clearly point to the small gear that meshes with the large gear before choosing an answer. • Confirm whether #1 and #3 are on the same shaft and whether the pinion is mounted on that shaft or on the lower one with #2. • Double-check if "between" in the chosen answer correctly matches the actual physical position of the pinion gear in the cross‑section (not just above/below visually).
