TPO-32 - Integrated Writing Task
Starting in the 1960s and continuing until the 1980s, sailors in Russian submarines patrolling the North Alantic and Arctic Ocean would occasionally hear strange sounds. These underwater noises reminded the submarine crews of frog croaks, so they called the sounds “quackers” (from the Russian word for frog sounds). The sources of the sound seemed to be moving with great speed and agility; however, the submarines’ sonar (a method of detecting objects underwater) was unable to detect any solid moving objects in the area. There are several theories about what might have caused the odd sounds.
The first theory suggests that the strange noises were actually the calls of male and female ocra whales during a courtship ritual. Orca whales are known to inhabit the areas where the submarines were picking up the bizarre noises. Orcas have been studied extensively, and the sounds they make when trying to attract a male are similar to those that the submarines were detecting.
A second idea is that the sounds were caused by giant squid. Giant squids are gaint marine invertebrates that live deep in the ocean and prey on large fish. They are difficult to detect by sonar because they have soft bodies with no skeleton. Not much is known about giant squid behavior, but their complex brains suggest they are intelligent animals. It is possible they have the ability to emit sound, and perhaps they approached the submarines out of curiosity.
A third theory suggests the Russian submarines were picking up stray sounds from some military technology, like another country’s submarines that were secretly patrolling the area. Perhaps the foreign submarines did not register on sonar because they were using a kind of technology specifically designed to make them undetectable by sonar. The strange froglike sounds may have been emitted by the foreign submarines unintentionally.
The professor cites several reasons to explain why the points made in the reading are likely to be wrong.
First, orch whales live near the surface of the ocean. While submarine mostly bases deep in the water, orch whale lives near the surface of the water. As a result, the sound they made with the purpose to attract mate is not possible to pass that far. Besides, if the sound is really made by the whales, they should be detected by the sonar.
Second, the giant squid continues to live after the sound disappeared in the 1980s. The sound was first detected in the 1960s and continue to be found for two decades. If it were the giant squids making the cracker sound, the sound should not have stopped suddenly in the 1980s, at the time when the giant squids were still alive.
Third, submarines cannot change direction quickly and will cause some sound when in use. The sound that the sonar detected has the characteristic of moving around and change direction quickly. But because of the development of technology at that time, there is no submarine can achieve this. Furthermore, if it were other submarines, there would be engine sound accompanying their operation.
To sum up, because of the aforementioned reasons, the professor suggests that the reasons mentioned in the reading passage are unlikely to be valid.
