When it comes to the source of odd sounds detected by Russian submarines from 1960s to 1980s, the speaker completely refutes the information from the reading material.
Initially, the author claims that the strange noises derived from the call of orca whales attracting a mate, which is similar to the sounds that the submarines found. However, the lecturer holds an opposite view. To be specific, it is known to us that orca whales live in the surface of ocean instead of deep sea where submarines usually sail. Evidently, those noises detected by those Russia submarines in the deep sea could not be the voice of Orcas who muttered on the surface.
In addition, in the passage, giant squid was brought under suspicion for the reason that they might emit some sound and even approach the submarines. The professor, nevertheless, argues against this viewpoint. To elaborate, the hazard occurred during only ten years, whereas if there are giant squid in that area, the noise would not disappear in ten years because they hardly migrate where they live for many years. As a result, the sound would continue for decades, which conflicts with the theory stated by the author.
Lastly, the writer professes that the sound was made by other submarines that were secretly patrolling in the deep sea. But from the listening, we know that direction of a submarine cannot change fast and acutely. While the sonar suggested that this object could divert its direction easily. Moreover, the engine of submarines are always accompanied with tremendous noise, which, as a matter of fact, these Russia submarines did not find at that time. So it is self-evident that this state made by the author is totally wrong.
