Question Focus: The diagram label points to the long moving part that pulls the train up the hill.
Correct Answer: G
Passage Reference: The traditional lifting mechanism is a long length of chain running up the hill under the track. The chain is fastened in a loop, which is wound around a gear at the top of the hill and another one at the bottom of the hill. The gear at the bottom of the hill is turned by a simple motor. This turns the chain loop so that it continually moves up the hill like a long conveyer belt.
Why this is correct: The diagram shows the long moving part under the track. The passage clearly says the lifting mechanism is a long length of chain that moves up the hill. So the answer is chain.
Common Mistake: Many students choose belt because the passage says "like a long conveyer belt". But that is only a comparison, not the real name. This is a paraphrase trap.
Paraphrasing: Passage: 'long length of chain running up the hill' = Diagram: 'moving lifting part'
Tips: When the passage says "like" or "as", look for the real object name, not the comparison.
Key Vocabulary:
- mechanism = machine part
- conveyer belt = moving belt
Question Focus: The diagram label points to the shape formed by the chain around the top and bottom.
Correct Answer: F
Passage Reference: The chain is fastened in a loop, which is wound around a gear at the top of the hill and another one at the bottom of the hill.
Why this is correct: The diagram shows the chain going around and coming back again. The passage says the chain is fastened in a loop, which matches this shape exactly. So the answer is loop.
Common Mistake: Some students choose gear because the loop goes around gears. But the label asks for the shape of the chain, not the wheel it wraps around. This is a context shift trap.
Paraphrasing: Passage: 'fastened in a loop' = Diagram: 'chain shape'
Tips: Check if the label wants a shape, a movement, or a machine part. Do not mix them.
Key Vocabulary:
- fastened = fixed
- wound around = wrapped around
Question Focus: The diagram label points to the round wheel at the top or bottom that the chain wraps around.
Correct Answer: B
Passage Reference: which is wound around a gear at the top of the hill and another one at the bottom of the hill.
Why this is correct: The diagram shows a wheel that the chain goes around. The passage clearly names this part as a gear. So the answer is gear.
Common Mistake: Students sometimes choose motor, but the motor turns the gear. It is not the wheel itself. This is a cause vs object confusion, a type of context shift trap.
Paraphrasing: Passage: 'wound around a gear' = Diagram: 'round wheel'
Tips: If two parts work together, ask which one you can actually see in the diagram.
Key Vocabulary:
- gear = toothed wheel
- wound = wrapped
Question Focus: The diagram label points to the power source that turns the gear.
Correct Answer: C
Passage Reference: The gear at the bottom of the hill is turned by a simple motor. This turns the chain loop so that it continually moves up the hill like a long conveyer belt. The coaster cars grip onto the chain with
Why this is correct: The diagram shows the device connected to the gear that makes it move. The passage says the gear is turned by a simple motor. So the answer is motor.
Common Mistake: Some students choose engine, but the passage clearly says the roller coaster has no engine. This is a contradiction trap.
Paraphrasing: Passage: 'turned by a simple motor' = Diagram: 'power source'
Tips: If the passage says something does NOT exist, never choose it from the options.
Key Vocabulary:
- motor = machine that makes things move
- turn = rotate
General Tips:
- Diagram labels usually follow the same order as the passage. Read from top to bottom.
- Always match the exact meaning, not a comparison or example.
- If two options seem similar, ask what the diagram label is really pointing to.
- Cross out each option after you use it to avoid repeating mistakes.
