In the given set of materials, the main topic is centered on what can be the origin source of anomalous sounds called "quackers". While the author has proposed three commonly theories, the speaker in the follow-up material challenged them in a number of ways.
The first point in the article is that as orca whales colonized in the same location and made a similar sound in order to mate with a male, it might be the noise of calling each other. However, this was questioned by the lecturer as she stated that if it was related to orcas, not only could the noise be detectable as it was produced near the water surface but also it had to be visible with sonars.
Moreover, according to the essay, the source of sounds might be giant squids lived in deep ocean without any hard tissue. In this regard, these species could not be observable by sonars. Nonetheless, the lecturer states that this bizarre sound stopped about two decades in the 80s, which caused the assumption to be invalidated.
Last but not least, the writer has asserted that this sound might emit from other military submarines designed with a high technology to be invisible. Conversely, according to the orator, the technology would not progress at this pace to produce such a fast and silent submarine.
