The reading and the listening are both about the " quackers." Which is an unidentified sound the Russian submarines heard through two decades in the North Atlantic and Arctic Ocean. The author of the reading believes that there are three possible theories about the source of this voice. The lecturer, on the other hand, challenges the statements made by the author. She is of the opinion that the source of the quackers is still anonymous. First of all, the author suggests that the odd noises were made by the females of Ocra whales to attract males during the breeding season. It is mentioned that these animals inhabit the area of the ocean where the sounds were heard. This argument is challenged by the professor. She says that these whales are indeed live there, but they live near the surface and not deep in the ocean where the submarine used to be. Furthermore, she argues that the sonars should be detected the existence of the whales. Secondly, the writer contends that the sound might be caused by a giant squid, emitted by them out of curiosity about the submarines, the article notes that this animal has no skeleton and that the reason it was not caught by sonar. The lecturer rebuts this by asserting that the voice was only soundable for twenty years, while the squid is still inhabiting the ocean until today, so there is no persuasive reason why this fish stopped abruptly making noises. Finally, it is stated in the passage that this sound might be from other military technology. The writer establishes that this encounterpoert submarine had been designed in a way that could not be detected by Russian technology. In contrast, THe professor posits that the noise was moving very quickly and quietly, she puts forward that there is no possible invention until this moment which can move in this silence and fast way.
