Passage Reference: In 1992, an offshore landslide caused a tidal wave of only about 3 feet high that struck a low tide, so Humboldt's County, where it hit

Common Mistake: Some students write landslide only. That loses an important detail and changes the meaning. This is a partial truth trap.

Paraphrasing: Transcript: 'an offshore landslide caused a tidal wave' = Diagram: 'cause of tsunami'

Tips: For cause labels, listen for phrases like caused by or was caused by.

Key Vocabulary:

• offshore = away from the coast
• landslide = large movement of earth

Question Focus: Wave height for the Pacific Ocean earthquake example

Correct Answer: zero feet

Passage Reference: On January 13, 1992, a Pacific Ocean earthquake off the coast of San Salvador, registering 7.6 on the Richersdale, didn't cause any ocean disturbance at all.

Why this is correct: The diagram asks for the wave height of this event. The speaker says there was no ocean disturbance, which means the height was zero feet.

Common Mistake: Students often write no wave or no disturbance, but those exact words are not in the diagram format. This is a synonym trap.

Paraphrasing: Transcript: 'didn't cause any ocean disturbance' = Diagram: 'wave height'

Tips: When you hear negatives like didn't or no, be careful not to miss them. This often signals the correct answer.

Key Vocabulary:

• disturbance = movement
• zero = none

Question Focus: Cause of the Papua New Guinea tsunami

Correct Answer: submarine earthquake

Passage Reference: This wave was caused by a magnitude 7.1 submarine earthquake.

Why this is correct: The diagram box points to the cause of the Papua New Guinea tsunami. The speaker clearly explains it was a submarine earthquake.

Common Mistake: Some students write underwater earthquake because it sounds similar. You must copy the exact words from the speaker. This is a paraphrase trap.

Paraphrasing: Transcript: 'submarine earthquake' = Diagram: 'cause'

Tips: In FIB questions, always copy the exact wording you hear, not your own synonym.

Key Vocabulary:

• submarine = under the sea
• magnitude = strength

Question Focus: Number of people killed in the Papua New Guinea tsunami

Correct Answer: 3000

Passage Reference: on July 17, 1998, was 23 feet high and killed at least 1,200 people. This wave was caused by a magnitude 7.1 submarine earthquake. On July 17, 1998, a Papua New Guinea tsunami killed roughly 3,000 people.

Why this is correct: The diagram asks for the number of deaths. The speaker says the tsunami killed roughly 3,000 people, so the correct number is 3000.

Common Mistake: Students sometimes write 1200 because it is mentioned earlier. That refers to a different event. This is a context shift trap.

Paraphrasing: Transcript: 'killed roughly 3,000 people' = Diagram: 'number killed'

Tips: When several numbers are mentioned, always check which event the diagram box refers to.

Key Vocabulary:

• roughly = approximately
• killed = caused deaths

Question Focus: Height of the wave caused by the ancient Norwegian landslide

Correct Answer: 30 feet

Passage Reference: Finally, about 8,000 years ago, a massive undersea landslide off the coast of Norway sent a 30-foot wall of water barreling

Why this is correct: The final box of the diagram shows the wave height from the Norway landslide. The speaker describes it as a 30-foot wall of water, which matches 30 feet.

Common Mistake: Some students write 40 feet because that number appears earlier for a different tsunami. This is a sequence trap.

Paraphrasing: Transcript: '30-foot wall of water' = Diagram: 'wave height'

Tips: Stay focused until the very end of the recording. The last answer often comes in the final example.

Key Vocabulary:

• wall of water = very large wave
• barreling = moving fast

General Tips:

• Diagram and table questions follow the order of the recording. Use the previous answer to know when the next one is coming.
• Always respect the word limit. Even one extra word makes the answer wrong.
• Copy the exact words you hear. Do not replace them with your own synonyms.
• Listen carefully for numbers and match them to the correct event.
• Watch for signpost words like 'however' and 'finally'. They often introduce new examples.
