The reading passage contends that there are three theories about what might have caused the sounds “quackers”, which seemed to be moving with rapid speed. On the other hand, the lecturer brings up several theories that contradict this argument.
First of all, the lecturer questions the validity of the reading passage’s theory that the sources of the sound were calls of ocra whales during a courtship ritual. This is attributed to the fact that even it is plausible, the whales live on the surface of ocean, not in the underwater. However, the source of quackers was detected from in deep underwater. Also, it is obvious that the location of the whales is detectable by scientists who are able to study them easily. Thus, the reading passage’s first theory is invalid.
Moreover, the lecturer cast doubt on the theory in the reading passage that the strange noises were caused by giant squid that live deep in the ocean. This is because the odd sounds were reported from 1960. However, from 1980, the sounds were disappeared out of the blue. In order to support this theory, it would be detected continuously because giant squids still live deep in the ocean. Consequently, the reading passage’s second theory is refuted.
Last but not least, the lecturer disagrees with the theory in the reading passage that the strange sounds detected by the Russian submarines were from some military technology which were patrolling the area secretly. It is obvious that no country could not have developed the technology which changes quickly the direction of submarine in company with silent engine sound as undetectable as by sonar. As a result, the reading passage’s final theory is contradicted.
