Score: 64.2

The author of the passage lists three pieces of evidence to illustrate that the humpback whales have the ability to navigate by the stars. However, the lecturer thinks the claims in the passage are inaccurate and faculty [wrong word/repetition  ] .

To begin with, the author suggests that because of the[ their ] complex brain, the humpback whales are intelligent enough to navigate by the stars. This specific argument is challenged by the lecturer. He who claims that there is no connection between high intelligence and navigating by the stars. Especially,[wrong word  ] while ducks also use the stars to navigate, the intelligence of ducks is in the average level of animals. Therefore, navigating by the stars seems to be an inborn ability that doesn’t [ informal writing ] have a close relation with intelligence.

Moreover, the author argues that the humpback whales move in straight lines because they use external marks such as the stars to navigate. However, the lecture rebuts this[unclear pronoun/use concrete noun  ] by mentioning that the external sign the whales relied on is the magnetic field. Since the humpback whales have biomagnetite, they are sensitive to the magnetic field on[article error  ] earth.

Finally, despite the author points out that the spy-hopping behavior of humpback whales is the evidence that they look at the stars, the lecturer contends that other animals such as sharks also have the action of spy-hopping.[ wordy ] Nevertheless, sharks do this not to migrate by the stars but to find the prey. Besides, humpback whales always show spy-hopping behavior during the days when there is no star in the sky.[  ]
