Difficulty: MediumDrawing Inferences and Implications

Read the following transcript excerpt from a science podcast report on marine bioacoustic tracking:

'While satellite tags offer precise coordinates when pelagic species breach the surface, they provide virtually no tracking data when hammerhead sharks remain submerged in deep ocean trenches for months at a time. To address this blind spot, our conservation team anchored passive acoustic listening stations directly along known bathymetric ridges. This underwater array automatically logs the high-frequency acoustic pings emitted by tagged sharks without requiring them to surface, although each station has an effective detection radius of only five hundred meters.'

Statement: Based on the audio report, the acoustic tracking system would be unable to record the movements of a tagged shark that migrates exclusively through open pelagic waters located several kilometers away from the submarine ridges.

Answer: Answer

Answer

The statement is true because the acoustic listening stations are restricted to bathymetric ridges with a five-hundred-meter detection radius, meaning pelagic movements several kilometers away fall outside the system's operational reach.
The inference is valid because swimming several kilometers away from the ridges places the tagged animal well beyond the five-hundred-meter detection threshold of the anchored receivers, leaving the submerged movement unrecorded.

Step-by-Step Solution

1
Identify the operational constraints of the tracking technology in the transcript.
Acoustic stations are anchored exclusively along bathymetric ridges and can only detect acoustic pings within a 500-meter radius.
Establishing the spatial constraints defined by the speaker is necessary to evaluate the system's reach.
2
Evaluate the shark's migratory scenario described in the statement against the network constraints.
The shark travels several kilometers away from the submarine ridges, exceeding the 500-meter receiver range.
Comparing the shark's distance with the detection radius determines whether logging occurs.
3
Synthesize the conclusion to confirm the validity of the inference.
The system will fail to record the shark's submerged trajectory under the stated conditions.
Connecting the technical limitations to the scenario validates the truth value of the statement.
