The article and the lecture are about three theories which have been proposed for clarifying the cause of a particular sound called “quackers” which was heard by sailors in Russian submarines in the 1960s. The author in the passage believes that those hypotheses are well-supported by certain evidence. However, the lecturer casts doubt on statements made in the reading. She thinks that those ideas are in debate since they present some problems for clarifying the cause of this phenomenon.
First, the author claims that one possible explanation is that the strange noises were produced by male or female orca whales which pretended to call each other during a courtship ritual. Nevertheless, this hypothesis is challenged by the lecturer who posits that despite living in these areas, they live on the surface and the submarine detected this sound in deep ocean which implies that it is unlikely that quackers have been heard by sailors and also under the circumstances the submarines’ sonar could have detected their movement.
Second, the article states that due to the soft bodies of giant squids, they could have produced this strange sound without being detected. Nonetheless, the lecturer discredits this point by clarifying that those quackers started being heard in the 1960s but suddenly stopped one decade later, although these marine creatures continue living in those areas which involve that they are not the transmitters of those sounds.
Finally, the author mentions that quackers could be produced by another foreign submarine which was secretly patrolling the area and they were not detected by the submarine’s sonar because the technology used presumably made it undetectable. The lecturer, on the other hand, puts forth the idea that it is unlikely that this type of submarine changed the direction so quickly and even today’s technology cannot make them so fast and silent as undetectable one.
