Practice Listening: Multiple Choice, Single Answer ID: #4643 Short Marlin
Instructions ›
Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

About ten years ago, a specialist in fish science found that blue marlin off the south-eastern United States would dive a half-mile deep when chasing prey, but the same species living off the coast of Costa Rica and Guatemala stayed near the surface. What was preventing these expert divers from diving? It turns out that the marlin near Central America wouldn't dive deep because they were avoiding a large area of water that contained too little oxygen to keep them alive. The discovery is an example of the many ways sea life is already changing in response to a new reality: climate change is causing reduced oxygen levels in marine waters. Denise Breitburg, senior scientist at the Smithsonian Research Center, states, 'This is a global problem, and global warming is making it worse. It requires global solutions.'

Option 2: "Climate change is a problem which requires global solutions."

Explanation: This option accurately reflects the main idea of the text. The speaker emphasizes that climate change is causing reduced oxygen levels in marine waters and highlights the need for global solutions, as stated by Denise Breitburg. This aligns with the overall theme of the text.

Option 1: "Marlin and other sea life are adapting to climate change."

Explanation: While the text mentions that sea life is changing in response to climate change, it does not specifically state that marlin and other sea life are adapting. The focus is more on the problem of climate change and its effects rather than adaptation.

Option 3: "Global warming is reducing oxygen levels in the ocean."

Explanation: Although the text mentions that climate change is causing reduced oxygen levels, this option is too narrow. It does not capture the broader message about the need for global solutions to address the problem, which is central to the speaker's argument.

Option 4: "Marlin have stopped diving deep in some areas."

Explanation: This statement is a specific detail from the text but does not represent the main idea. The text discusses the behavior of marlin in relation to climate change but does not focus solely on their diving habits. Therefore, it does not encompass the broader implications of climate change that the speaker is conveying.
