Both the reading passage and the lecture are about a strange sound called quackers that happened between 1960s till 1980s, and suddenly disappeared after that. Although the article highly suggests three reasons for the phenomenon, but the lecturer casts doubt on all of them and believes no one knows the real reasons and that the hypotheses suggested in the article have certain problems.
First, one might think the idea of male and female orca whales noise, pointed in the article, might sound logical, but the lecturer rejects the idea. She points to the fact that these marine animals live near the surface of water, while the submarine went deep into water. Thus it's not plausible to hear the noise of whales in that depth. Moreover, since whales are detectable with sonar, researchers must be able to detect them but couldn't. That's another proof for refuting the issue of whales.
In addition, the reading passage mentions giant sqids as a candidate for producing the noise and because they're not detectable with sonar, it can be a good guess at the first glance. Albeit giant sqids are a better candidate for the mystery, but we come up to this question that why did the noise disappear just after 1980 while the giant sqids lived in the ocean after that and do still live there? It doesn't seem reasonable to hear the noise just for two decades and then suddenly stop hearing it.
Last but not the least, the article points to a foreign submarine, but the lecturer challenges the idea, as we don't have the technology to build such quick submarines. Additionally, submerine's engins don't produce such low noise and even today, in this decade, we haven't been able to build a fast and low noise submarine like that. To conclude from what the lecturer said, it sounds impossible to believe in a foreign submarine.
