Practice Listening: Multiple Choice, Single Answer ID: #41029 Short Powered Flight

Instructions ›

You will see a video about the pioneering advancements in solar-powered flight technology. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

Solar powered flight offers the possibility of remaining perpetually in the air like a satellite within the atmosphere. The pilotless Pathfinder, created in 1994 by Aerovironment, is a major step toward realising that goal. This ultralight has a 100-foot wingspan, made almost entirely of solar panels. The panels convert the sun's energy to electricity, which powers the plane's 8.5 horsepower. Orders later designs will be able to store enough electricity to allow the drone to fly through the night, and they'll possess the stability and power to remain above the cloud cover in the thin upper reaches of the atmosphere. Eternal planes such as this one may one day provide important storm tracking services, military observations, and communication capabilities.

What is the significance of the Pathfinder's design in the development of solar-powered flight?

Option 2: "He flew without a radio to communicate his position."

Explanation: This option is correct as the text explicitly mentions that Lindbergh took off 'with no radio to communicate his position.' This detail highlights a significant challenge he faced during his flight, as lacking a radio would have made navigation and communication extremely difficult.

Option 1: "He had multiple co-pilots to manage during the flight."

Explanation: This option is incorrect because the text states that Charles Lindbergh flew solo, meaning he did not have any co-pilots. The phrase 'flew solo' indicates that he was alone in the cockpit, which contradicts the claim of having multiple co-pilots.

Option 3: "He faced unexpected bad weather halfway through the flight."

Explanation: This option is incorrect because the text does not mention any bad weather during Lindbergh's flight. Instead, it describes the morning as foggy but does not indicate that he encountered unexpected weather challenges during the journey.

Option 4: "He had to make several emergency landings along the way."

Explanation: This option is incorrect as the text does not state that Lindbergh made any emergency landings. It describes his flight as a continuous journey from New York to Paris without mentioning any need for landings, which suggests that he completed the flight without significant interruptions.
