A.I. Explanation:

Question Focus: The diagram arrow points to the wheel that the water hits first.

Correct Answer: I

Passage Reference: The water enters through a hose pipe, and then it turns a water wheel. You can see where the wheel is marked by an arrow pointing upwards. It's called a water wheel

Why this is correct: At the beginning of the process, the speaker explains that water turns a water wheel. The arrow on the diagram pointing upward matches this part exactly.

Common Mistake: Students sometimes choose gears because both parts rotate. But the speaker clearly names this part as the water wheel. This is a paraphrase trap.

Paraphrasing: Transcript: 'turns a water wheel' = Diagram: 'water wheel'

Tips: When the speaker defines something by name, that is usually a direct diagram label.

Key Vocabulary:

• turns = makes rotate
• wheel = round part

Question Focus: The diagram shows the moving mechanical parts after the water wheel.

Correct Answer: F

Passage Reference: This action spins a series of gears. How are you going to describe the gears? There are two worm gears. one vertical and one horizontal. The horizontal worm gear drives a circular gear.

Why this is correct: The label is next to several toothed wheels inside the sprinkler. The speaker says the water wheel spins a series of gears, so the correct word here is gears.

Common Mistake: Some students choose crank because it is mentioned soon after. But the crank is already labelled on the diagram. This is a distractor trap.

Paraphrasing: Transcript: 'a series of gears' = Diagram: 'gears'

Tips: If the speaker says something is already labelled, do not use that word again.

Key Vocabulary:

• spins = turns
• series = several

Question Focus: The diagram label points to the long tube that carries water upward before it comes out.

Correct Answer: D

Passage Reference: Okay, then you could say the water passes through the spray tube.

Why this is correct: The diagram sentence is about where the water goes next. You hear the speaker say the water passes through the spray tube, so the correct label for that long pipe is spray tube.

Common Mistake: Students sometimes choose hose pipe because it also carries water. But the hose pipe is where water enters at the start. This is a sequence trap.

Paraphrasing: Transcript: 'passes through the spray tube' = Diagram: 'spray tube'

Tips: Follow the water path step by step. Diagram labels usually follow the same order as the speaker.

Key Vocabulary:

• passes through = goes through
• tube = long pipe

Question Focus: The diagram shows the top of the spray tube where water comes out, and asks what parts spread the water.

Correct Answer: A

Passage Reference: And the water is then spread over the lawn through holes at the top of the spray tube.

Why this is correct: The diagram label is at the very top of the spray tube where water exits. The speaker clearly says the water is spread over the lawn through holes. That directly matches what the diagram is pointing to.

Common Mistake: Some students choose spray tube because it is mentioned in the same sentence. But the label points to the openings, not the tube itself. This is a partial truth trap.

Paraphrasing: Transcript: 'through holes' = Diagram: 'holes'

Tips: When a diagram arrow points to small details, listen for words like holes, openings, or ends.

Key Vocabulary:

• spread = sent out
• holes = small openings

Question Focus: The diagram label is at the bottom showing what the sprinkler stands on.

Correct Answer: B

Passage Reference: How are you going to describe the gears? There are two worm gears. one vertical and one horizontal. The horizontal worm gear drives a circular gear. That gear is connected to a crank, which changes the motion. The crank is already labelled. Do you see the two white arrows? I see. OK. The water has passed across the water wheel. Then what? Okay, then you could say the water passes through the spray tube. Yes, I see. And the water is then spread over the lawn through holes at the top of the spray tube. How are you going to describe the base? How about this? The sprinkler stands on a base consisting of two metal tubes. which join at a hinge at one end and continue into a plastic moulding at the other. That's certainly starting at the bottom.

Why this is correct: The label is clearly at the bottom of the diagram. The speaker says the sprinkler stands on a base, so the correct answer here is base.

Common Mistake: Students sometimes choose hinge because it is mentioned in the same description. But the hinge is only one part of the base, not the whole bottom. This is a partial truth trap.

Paraphrasing: Transcript: 'stands on a base' = Diagram: 'base'

Tips: Bottom diagram labels usually match words like base, bottom, or support.

Key Vocabulary:

• base = bottom support
• stands on = rests on

General Tips:

• Diagram labels usually follow the same order as the recording, from top to bottom or start to finish.
• Listen carefully when the speaker describes where something starts or ends. This often matches diagram positions.
• If two options seem similar, check which one fits the exact place the arrow is pointing to.
• When the speaker says something is already labelled, do not choose that word again.
• Always track the process step by step, especially when water or movement is described.
