Difficulty: MediumExtracting Supporting Details and Facts

A marine biologist delivers an oral presentation on seabird conservation in the Beagle Channel: 'Over a four-year tracking project in the Beagle Channel, our research team deployed GPS telemetry tags on 80 adult Magellanic penguins. Our collected data revealed that during the chick-rearing phase, the penguins traveled an average foraging distance of 28 kilometers per trip, with 75 percent of their dives targeting depths between 15 and 30 meters where juvenile Fuegian sprat congregate.' Based on the presentation, during the chick-rearing phase, three-quarters of the tagged penguins' foraging dives occurred at depths between 15 and 30 meters.

Answer: Answer

Answer

True
The statement is confirmed as true because the presenter directly reports that 75 percent (three-quarters) of the foraging dives took place between 15 and 30 meters in depth.

Step-by-Step Solution

1
Locate the specific supporting detail in the presentation that addresses the dive depth of Magellanic penguins during the chick-rearing phase.
Identified the segment stating that 75 percent of their dives targeted depths between 15 and 30 meters.
Accurately identifying the exact factual segment is necessary to verify supporting evidence.
2
Compare the quantitative data and depth range in the statement to the transcript details.
The numerical fraction 'three-quarters' matches '75 percent', and the specified depth range of '15 and 30 meters' matches the audio text directly.
Direct alignment between the transcript evidence and the statement proves factual validity.
