Quakers are the odd underwater sounds in the North Atlantic and Arctic Ocean moving fast, which cannot be detected by the submarine's sonar. The passage presents three hypotheses regarding the causes of Quakers, all of which are contested by the lecture.
First off, the professor dismisses the orca theory with two arguments. On one hand, orcas always live in the surface of water rather than deep marine, although the two kinds of sounds are similar with each other. One the other hand, if orcas had indeed strayed nearby the submarines, they should been captured by sonar.
In addition, that giant squids, known as intelligent animals, emit the sound with curiosity about the submarines is also dismissed by the professor. In her view, Quakers were first detected in the 1960s and disappeared by the 1980s. While, giant squids continue to live in the deep ocean. She argues that if squids were the source, there would be no explanation why the Quakers started and ended all of a sudden.
Last, it’s considered incredible that the sounds come from foreign military technology. First, Quakers must change directions quickly and are capable of moving around, but no submarine at that time was this agile. Second, the Quakers were quite silent sounds, but all submarines at that time would emit engine sounds.
