In the given set of materials, the main topic is centered on what can be the origin source of anomalous sounds called "quackers" and people make several commonly theories to explain them. On the contrary, the speaker points that all the theories have arguments.
To begin with, the claim that quackers are the calls of ocra whales seems plausible, however, it is highly unlikely. The professor asserts that ocra whales live in the surface water not the deep ocean where the submarines remain. Also, even if there are orca whales, submarines could detect nearby whales by sonar. So orca whales cannot be the sources of the quackers.
Then, according to the author, quackers are caused by giant squid lived in deep ocean without any hard tissuethat is also again by the speaker. She tells us that if this theory is true, we could always hear the strange sound because giant squids are still alive. In fact, quackers which started in the 1960s disappeared after 1980s. Thus this assumption is invalidated.
In addition, the speaker also disapproves the third theory that they come from military technology like other country’s submarines. No submarines have the ability to change the directions so quickly. She also illustrates that till now, we have not own the technology to build a submarine with both fast speed and silent engines.
