what is the source of the sound?
The reading and lecture are both about quackers, which started in the 1960s and then stopped in the 1980s. The author of reading believes that there are some theories that can show sources of the sound. The lecture challenges the theories made by the author. The professor is of the opinion that these reasons are wrong.
First of all, the author suggests that the strange noises were related to the male and female orca whales, which alive in the areas where the submarines were picking up the sounds. This hypothesis is challenged by the lecture. She says that the orca whales settle in the area where the submarines heard the noises, but most of them live near the surface of the water while the submarines are in the deep zone, so the submarines could not hear whales' voices.
Secondly, the writer contends that the sounds were made by giant squids because they have complex brains, which can send sounds into the environment. Also, the article notes the sonar system cannot recognize giant squids because they are creatures that have no skeleton in the body. The lecture, however, rebuts this by asserting that the submarines detected the noises between two decades, and after that, the sounds disappeared. She elaborates on this by mentioning that giant squids have lived in the area until now, consequently, there is no rational reason that these animals were started to send the noise at the specific time and suddenly stop it.
Finally, it is stated in the article that Russian submarines were catching the sounds from foreign submarines that were patrolling the area, moreover, other submarines designed by specific apparatus that were undetectable by sonar. The lecture, on the other hand, posits that this statement has a problem because the source of sound appear to move and change direction very fast, whereas the submarines cannot do this work. Besides, she mentions that even today there are no submarines that can move and change a route quickly.
