Practice Listening: Multiple Choice, Single Answer ID: #4145 Short Seawater
Instructions ›
Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

Using NOAA's extreme sea level rise estimate, recommended for forecasts involving long-term infrastructure like this, the researchers say that 15 years from now, 4,100 miles of fiber-optic cable could be underwater. And 1,100 internet hubs could be surrounded by water. And remember, our land-based infrastructure isn't waterproof, like transoceanic cables are. "Seawater comes in, and cabling is not meant to work underwater. So signals will be interrupted and dropped. You know, the actual infrastructure itself might deteriorate." The researchers presented the peer reviewed findings at the Applied Networking Research Workshop in Montreal this week. They also write that large internet service providers including AT&T, Century Link and Inteliquent face the greatest risk. So if these predictions play out, internet companies need to harden their networks soon, they say. Or we could lose service during the emergency right when we need it most.

What does the speaker say is most vulnerable to sea water?

Option 3: "The biggest internet service providers"

Explanation: The text states that large internet service providers, including AT&T, Century Link, and Inteliquent, face the greatest risk from seawater. This aligns directly with the question about what is most vulnerable, as the researchers emphasize the need for these companies to harden their networks.

Option 1: "Emergency lighting networks"

Explanation: The text does not mention emergency lighting networks as being vulnerable to seawater. Instead, it focuses on internet infrastructure, specifically mentioning internet service providers and fiber-optic cables.

Option 2: "Chinese infrastructure companies"

Explanation: The text does not reference Chinese infrastructure companies at all. It specifically discusses large internet service providers like AT&T and Century Link, making this option irrelevant.

Option 4: "New transoceanic cables"

Explanation: The text mentions that transoceanic cables are waterproof, indicating they are not vulnerable to seawater. This contradicts the idea that new transoceanic cables would be at risk, making this option incorrect.
