A.I. Explanation:

Question Focus: Identifying the main supporting structure attached to the plinths

Correct Answer: frame

Passage Reference: with two giant plinths pointing up onto which an A-frame was attached, like a giant letter.

Why this is correct: On the diagram, this label points to the large angled structure holding the wheel. You hear the speaker say an A-frame was attached, which is commonly shortened to frame on diagrams.

Common Mistake: Some students write plinths because they hear that word first, but the arrow points to what is attached on top of them. This is a context shift trap.

Paraphrasing: Transcript: 'an A-frame was attached' = Diagram: 'frame'

Tips: Look carefully at what the arrow touches, not just the word you hear first.

Key Vocabulary:

• frame = supporting structure
• attached = fixed to

Question Focus: Identifying the structure placed over the piles

Correct Answer: base cap

Passage Reference: once these were securely in place, a base cap was installed over them as a kind of lock

Why this is correct: The label points to the flat structure sitting on top of the piles. The speaker clearly says a base cap was installed over them, which matches this position.

Common Mistake: Students sometimes write lock because the speaker uses that word as a description, but it is not the actual name. This is a paraphrase trap.

Paraphrasing: Transcript: 'a base cap was installed' = Diagram: 'base cap'

Tips: Ignore descriptive words and listen for the technical name.

Key Vocabulary:

• base = bottom
• cap = cover

Question Focus: Identifying the type of piles driven into the ground

Correct Answer: tension

Passage Reference: tension piles were being driven into the ground beside the River Thames.

Why this is correct: The arrow on the diagram points to the underground supports. You hear tension piles being driven into the ground, so the correct label is tension.

Common Mistake: Many students write piles, but the diagram already shows piles and needs the type. This is a partial truth trap.

Paraphrasing: Transcript: 'tension piles' = Diagram: 'tension'

Tips: When a compound term is used, the diagram may only need one key word.

Key Vocabulary:

• tension = pulling force
• pile = deep support post

Question Focus: Identifying how the capsules are attached to the rim

Correct Answer: rings

Passage Reference: each one linked by mounting rings that would support eager viewers as they rose above London.

Why this is correct: This label points to the small circular parts connecting the capsules to the wheel. The speaker says they are linked by mounting rings, so rings is correct.

Common Mistake: Students sometimes write spokes because they hear that earlier, but spokes connect the rim to the center, not the capsules. This is a context shift trap.

Paraphrasing: Transcript: 'mounting rings' = Diagram: 'rings'

Tips: Match the word to the exact part shown, not just something nearby.

Key Vocabulary:

• mounting = fixing
• rings = circular connectors

Question Focus: Identifying the area where visitors get on

Correct Answer: boarding platform

Passage Reference: And the last thing to be built is the first thing the visitor encounters, the boarding platform laid down underneath.

Why this is correct: The diagram label points to the flat area under the wheel where people enter. The speaker clearly names this as the boarding platform.

Common Mistake: Some students write platform only, but the full name is required and within the word limit. This is a partial truth trap.

Paraphrasing: Transcript: 'boarding platform' = Diagram: 'boarding platform'

Tips: If the speaker gives a full term and it fits the word limit, copy all of it.

Key Vocabulary:

• boarding = getting on
• platform = flat area

General Tips:

• Diagram questions follow the order of the recording, so use each answer to predict where the next one is coming.
• Always look at what the arrow touches on the diagram before choosing a word.
• Use the exact word you hear from the speaker, not a synonym.
• Check the word limit carefully. One extra word makes the answer wrong.
• Listen for technical names, not descriptive explanations.
