Practice Listening: Multiple Choice, Single Answer ID: #3754 Short Animals and Noise

Instructions ›

Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

Animals as well as humans are effected by noise. There is evidence to show that some whales, for example, died when they beached themselves after being exposed to excessive sonar-the noise produced by submarines as they navigate underwater. It’s been shown that whales produced louder sounds when communicating with each other when sonar equipment was on in their vicinity. This was doubtless because they needed to make themselves heard by their fellows, perhaps to warn each other of danger, or tell one another about a food source. Another example of how noise can affect animal behavior is given by the European robin. In urban areas this small bird sings at night rather than during the day.

What is the main point the speaker is making about whales and sound pollution?

* Listen to the recording and select the correct answer

Increased sound pollution means whales ‘talk’ more at night than during the day Research shows whales communicate to warn each other of sound pollution Whales may not survive in some situations where there is sound pollution Sound pollution from submarines has little impact on whales and other creatures

Option 3: "Whales may not survive in some situations where there is sound pollution"

Explanation: This option accurately reflects the main point of the text. It discusses how excessive sonar can lead to dangerous situations for whales, such as beached whales that die after exposure to sonar. This aligns with the overall theme of the text regarding the negative impact of sound pollution on whale survival.

Option 1: "Increased sound pollution means whales ‘talk’ more at night than during the day"

Explanation: This option incorrectly states that whales talk more at night due to sound pollution. The text does not mention whales singing at night; it specifically discusses their increased vocalization during the day when sonar is present. Therefore, this option misrepresents the information.

Option 2: "Research shows whales communicate to warn each other of sound pollution"

Explanation: This option suggests that whales communicate specifically to warn each other about sound pollution. However, the text indicates that whales increase their vocalizations to communicate with each other in response to sonar noise, not specifically to warn about sound pollution. This misinterpretation leads to its incorrectness.

Option 4: "Sound pollution from submarines has little impact on whales and other creatures"

Explanation: This option contradicts the text, which provides evidence that sound pollution from submarines has significant effects on whales, including increased vocalization and instances of death when beached. Therefore, stating that it has little impact is inaccurate and misleading.
