The article discusses the strange sounds that were heard by Russian submarines that they called them "quackers" and provides three theories to unravel the mystery. The professor, however, believes that these theories are not accountable, and the scientists are still arguing about the source of the quackers, and she refutes each of the author's reasons.
First, the article explains that the sound could be emitted from orca whales during their courtship ritual. The professor doesn't agree with this point and states that it is highly unlikely. Because orca whales swim on the surface of the ocean, and submarines couldn't have heard their noises since they swim in deep surfaces. Moreover, the submarines should have monitored them by their sonar equipment, which they didn't.
Second, the author claims that it might have been a giant squid which made the noise. The professor refutes this point and states that the quacker sounds were heard only during the 1960s until the 1980s, and since the squids are always present in the area, they can't be the cause of the noises, and suddenly went silent.
Finally, the article indicates that it could be one of the other countries military submarines that made the noises. The professor disagrees with this point as well, and she says that it isn't possible. She explains that the source of the sound was moving quickly, and there wasn't engine noises companying the quackers. Therefore, the noises couldn't have been produced from submarines, since the movements were too fast, and no submarine could move that fast.
