A misplaced filter label breaks the route

  • Outcome: relate a passage description to a labelled part, layer, branch or process stage, then copy the precise label within its local limit. Start with Reading orientation. Swapping a filter’s labels can send someone to the wrong component even when the copied words are spelled correctly.
  • Follow the drawing’s arrows or leader lines together with the passage’s relationships. These original schematic cases need no outside technical knowledge and offer no band prediction or timing calibration. A component diagram may use no flow arrows at all; locate the leader line’s endpoint instead.

The following passage and diagram are original practice material, not an official test item.

Water collected from a roof enters a filter at the top. A mesh screen catches leaves before the water reaches a layer of gravel, which holds back larger particles. Below the gravel, fine sand removes smaller particles. At the base, filtered water flows into a covered storage tank. A pump sends water from the tank to a garden when it is needed. The filter does not make the water safe to drink.

Read the diagram in the direction of the arrows before searching for any answer. This fixes the position of each missing label.

The diagram cannot hand you the answer just because it looks friendly.
