Script

Well, ongoing investigations have revealed that predation is the most likely cause of sea otter decline after all.

First, the pollution theory is weakened by the fact that no one can really find any dead sea otters washing off on Alaskan beaches. That's not what you would expect if infections caused by pollution started killing a lot of otters. On the other hand, the fact that it's so hard to find dead otters is consistent with the predator hypothesis. If an otter is killed by a predator, it's eaten immediately so it can't wash up on shore.

Second, although orcas may prefer to hunt whales, whales have essentially disappeared from the area because of human hunters. That means that orcas have had to change their diet to survive and since only smaller sea mammals are now available, orcas have probably started hunting those. So it probably is the orcas that are causing the decline of all the smaller sea mammals mentioned in the passage - the seals, the sea lions and the sea otters.

And third, the uneven pattern of otter decline is better explained by the orca predation theory than by the pollution theory. What happens to otters seems to depend on whether the location where they live is accessible to orcas or not. In those locations that orcas can access easily, the number of sea otters has declined greatly. However, because orcas are so large, they can't access shallow or rocky locations, and shallow and rocky locations are precisely the types of locations where sea otter populations have not declined.

Sample Answer

By Holly Lin (314 words)

The author talks about the cause of the decline of sea otters, and points out that pollution seems to be the main reason. The speaker, however, suggests that predation ought to be the deciding factor behind this phenomenon.

First, the writer mentions that oil rigs and other sources of industrial chemical pollution are indeed found along the Alaskan coast, and thus could have decreased the sea otter's resistance to diseases, further resulting in its decline. In contrast, the professor reminds that if this were the case, dead sea otters could have easily been seen along the shore, and since this did not happen, the predator hypothesis seems to be more persuasive, as it suggests that sea otters were eaten immediately after they were killed.

Second, the writing passage argues that the pollution theory applies as the entire ecosystem in the region seems to be affected, with the population of seals, sea lions and sea otters decreasing at the same time. Besides, although orcas may have been the cause of such large scale decline, these predatory creatures prefer hunting larger preys such as other whales; thus the predator hypothesis can be safely ruled out. Yet the speech points out that orcas can actually be the real cause behind this large scale reduction of multiple species, due to the fact that whales have decreased greatly in number because of human hunters, thereby forcing orcas to change their eating habits and hunt smaller preys.

Thirdly, the article states that the uneven pattern of otter decline suggests that ocean currents may have led to uneven concentrations of pollutants along the coast. However its listening counterpart refutes this belief, by stating that the uneven pattern can be better explained by the predation theory; in other words, orcas are large creatures and have trouble accessing shallow or rocky locations, which are exactly areas where sea otters are stable in number.
