Both the lecturer and the reading passage discuss whale stranding. The lecturer, however, refutes the author's claim on few possible reasons for whale stranding, by presenting three counter-arguments.
First, the lecturer claims that whale stranding due to wind patterns is disputable. The author does not account for the fact that whales exist all over the world where there are various wind patterns. For example, the wind pattern in the west part of US is different from the east region. This counters the author's claim that the flow of wind, due to wind patterns cause whales to be stranded.
Second, the lecturer asserts that illness would unlikely be the reason for whale stranding. This is because healthy whales are also stranded and stranded whales are able to swim again once they are put back in to the sea. This refutes the author's assertion that illinesses causes living whales to be stranded near shore.
Lastly, the lecturer says it is controversial that whales which are unable to detect coaslines become stranded. He says that only some whales end up in the beaches althoughh all whales use the same sonar system. Also, whales that live by the coastline, that are infact more possible to become stranded, rarely become stranded. This opposes the author's statement that coastlines that whales cannot detect cause them to be stranded.
