Essay topics:

Starting in the 1960s and continuing until the 1980s, sailors in Russian submarines patrolling the North Atlantic 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 orca 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 mate are similar to those that the submarines were detecting.

A second idea is that the sounds were caused by giant squid. Giant squid are giant 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 the 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.

Recently, there has been a debate on the sound heard underwater(Quakers).More specifically, in the reading passage, the writer puts forth three possible theories that might have caused the unusual sounds.In the listening, the lecturer is quick to point out that there are some serious flaws in the writers claim.In fact, he believes and addresses, in detail, the trouble with each point made in the reading text.

First and foremost, the author of the reading states that the odd nose is caused by male and female orca during conception rituals.Some professional, in the same field, however, stand in firm opposition to this claim.In the listening, for example, the professor states the orca leaves in shallow water, while the submarine leaves in deep sea water.Therefore they would not detect the sound.

One group of scholars, represented by the writer, thinks that another cause could be the presence of grant squid because they reside in the ocean and feed on big fish. Of course, though, not all experts in the field believe this is accurate.Again, the speaker addresses this point by claiming that the giant squid are detected in 1960 and analysis has shown that it continues for twenty years.Moreover, squid stays in the ocean while the russian submarine were patrolling.Therefore the sound would have be heard if it was truly the quaint squid.

Finally, the author brings his argument to a close by suggesting that the submarines pick up sounds from military technology the same as other countries that hid while patrolling in the area.Not surprisingly, the professor takes issue with this by contending that the sonar sounds revolve around because the submarine produces engine noise.Moreover, there hasn't been any useful apparatus to build a fast submarines.
