The listening and reading material have a discussion about whales migrate behavior. The

writer give three reasons to argue that humpback whales use stars to migrate. However, they

are all against by the speaker in the listening passage.

Firstly, admitting that humpback whales are highly intelligence as the author claim, the

speaker strongly believe that there are no connection between intelligence and the ability to

use star to navigate. Since many birds, for example, ducks, can use stars to find their directions.

However, the intelligence of ducks are only among the average, thus, the fact that humpback

whales are highly intelligent cannot make them use stars to navigate.

Secondly, the writer hold the opinion that whales can migrate straight forward only because

passage claims. The speaker thinks it has nothing to do with using stars for migration. Though

these behavior is rare, there are animals raise head during thing which is not migration. Take

shark as an example, they often looks forward while hunting. Besides, whales often raise their

head during daytime. Since no stars can be seen under sunlight, these behavior can not be a

reason for the claim.
