Reading Time: 3 minutes

Sea Otters

Researchers were alarmed by the rapid decline of sea otter populations along the coast of Alaska, which play a vital role in the health of the ecosystem. Two main theories emerged to explain the die-off: environmental pollution and increased predation.

Pollution initially seemed like the most likely culprit. Known sources of pollution, like oil rigs, existed along the coast. Additionally, water samples revealed elevated levels of chemicals known to weaken immune systems, potentially leading to otter deaths.

Another piece of evidence for pollution was the decline of other sea mammals, like seals, in those areas. This suggested a broader environmental factor harming various species, which is a characteristic of pollution rather than targeted predation. Typically, predators that hunt across large areas, like orcas, focus on bigger prey.

Finally, scientists believed pollution could explain the uneven decline observed. Some otter populations saw drastic drops, while others remained stable. Ocean currents or other factors might have caused uneven distribution of pollutants along the coast, according to some experts.

Now play the Audio. 

Question:

Summarize the points made in the lecture and explain how the speaker cast doubt on specific points made in the reading passage.

Response Time: 20 minutes 

Transcript of the Audio for the Integrated Writing Task on Sea Otters

Professor: New research suggests that sea otters are most likely being eaten by predators, not dying from pollution.

Firstly, unlike what we'd expect if pollution were causing illness, there aren't many dead otters found on Alaskan beaches. This lack of carcasses actually strengthens the predator theory. If a predator hunts an otter, it likely eats it whole, leaving nobody to wash ashore.

Secondly, orcas typically hunt whales, but due to human hunting, these whales have vanished from the area. With fewer whales available, orcas have likely adapted their diet to include more readily available prey. This shift towards smaller sea creatures, including otters, could explain the decline in all the mentioned species.

Finally, the uneven pattern of the decline further supports predation as the cause. Otter populations in areas easily reached by orcas have suffered more, while those in shallow, rocky areas where orcas can't go have remained stable.

Sample Responses for the Integrated Writing Task on Sea Otters

For your benefit, we have included two sample responses below, representing contrasting proficiency levels (high-level and mid-level). A comparative analysis of these responses will equip you with valuable insights into the key linguistic elements that contribute to achieving a superior score on the TOEFL.

Mid-Level Response

The professor said pollution isn't the main reason for fewer sea otters. Unlike the passage, they say there aren't many dead otters, which wouldn't happen if pollution made them sick. The lecture also mentioned orcas having to eat different things because humans hunted their usual food, leading them to eat otters. Finally, the professor explained why some otter populations are stable – they live in areas where orcas can't reach them. (70 words)

Rater’s Comment 

This response effectively summarizes the key points from the lecture (pollution not the main cause, orca diet shift, location impacting otter populations) and highlights the contradiction with the reading passage (lack of dead otters). Here are some suggestions for improvement. Consider replacing "fewer sea otters" with "sea otter decline" for improved clarity. While the answer is clear, consider replacing "having to eat different things" with "switching prey" to demonstrate a wider vocabulary range. "Unlike the passage" can be replaced with a transition phrase like "contradicting the passage" to show a stronger understanding of the task (identifying contrasting information). Overall, this is a mid-level response that demonstrates an average grasp of the lecture's content and its relation to the reading passage.

High-Level Response 

The text and the lecture both address the concerning decrease in sea otter populations, but they differ on the main culprit. The reading points to environmental pollution along the Alaskan coast as the cause, while the lecture emphasizes predation by other animals. Firstly, the reading blames pollution sources for the decline, while the lecture argues that predators are directly responsible for hunting and consuming the otters. Secondly, the reading suggests pollution has a greater impact on otters due to the death of other marine mammals. The lecture counters this by proposing that the decline in orca populations, another prey for these predators, is also due to predation. Human hunting eliminated the whales, the predators' primary food source, forcing them to switch to smaller prey like orcas and eventually sea otters. Thirdly, the reading claims pollution explains the uneven decline patterns observed in otter populations. The lecture disagrees, attributing it to predator presence. The lecturer argues that areas with a robust predator population, like orcas, have lower sea otter numbers, whereas regions where these predators are scarce see a more stable otter population. In conclusion, the text and the lecture offer contrasting perspectives on the cause of the sea otter decline, with pollution versus predation being the central debate. (207 words)

Rater’s Comment

This response effectively summarizes the key points from both the reading passage and the lecture, highlighting the contrasting views on the cause of the sea otter decline. The use of transition words ("Firstly," "Secondly," and "Thirdly") helps structure the response and clarifies the progression of arguments. Additionally, the answer accurately explains how the lecture contradicts specific points from the passage. However, for a stronger response, consider including a sentence or two that demonstrates a deeper understanding of the connection between the arguments. Overall, a clear and well-organized response demonstrates a good grasp of the contrasting viewpoints.
