The lecture and the reading passage give contradictory opinions on the topic of the decline of the sea otters, [ punctuation error ]the explanation of the decline is environment[ word form error ] pollution or predator attacks[unclear sentence  ]. The author gives arguments [argues  ]in favor of the former[  unclear pronoun],[ punctuation error ] nevertheless, challenged by the professor with a counterpoint and well-structured analysis[grammatical error  ].

Firstly, although the author believes that the sea otters were killed by[demised as a result of an  ] industrial chemical pollution basing[ word form error ] on water samples with[ unclear preposition ] increasing levels of chemicals, the professor refutes that argument by pointing out the absence of dead sea otters which were washed to shore[ lengthy unclear; split it ]. If the otters were killed by chemical pollution, there must[grammatical error  ] be observable dead otters, while the preyed otters are on the contrary[  unclear writing].

Secondly, the professor posits, [unclear; grammatical error  ]since the predators of the otters can[could  ] change their diet, that is, preying [preposition error  ]other animals to ensure the[article error  ] food supplication, the decline of a variety of animals cannot only be due to the chemical pollution, which is incongruous with the author[  unclear writing].

Lastly, the professor asserts that we can clarify the uneven pattern of otter decline through[using  ] (the predation theory rather than pollution)[incorrect comparison  ]. She contends that the accessibility of a location for predators[ ‘ access to a location ] is the decisive factor regarding the decline of otters. For instance, the shallow and rocky locations are hard to access, while the number of otters is scarcely reduced there.[be consistent with tense  ]
