Practice Listening: Multiple Choice, Single Answer ID: #36640 Short Ethanol
Instructions ›
Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.
In 2015 alone, the ethanol industry created and supported more than 350.000 jobs. Ethanol also contributed nearly S44 billion to the U.S. Gross Domestic Product (GDP) — a number exceeding the total GDP of many countries. And the production of 14.7 billion gallons of ethanol means that the U.S. needed to import 527 million fewer barrels of crude oil to meet the country's demand for gasoline. New technologies are helping make Earth-friendly American ethanol even more sustainable. Enogen corn enzyme technology, available only from Syngenta, is an in-seed innovation and the industry's only corn designed specifically to enhance ethanol production. By incorporating grain from Enogen corn hybrids into its existing production process, an ethanol plant can reduce the viscosity of its corn mash from a consistency of oatmeal to lemonade, enhancing production efficiency and decreasing costs.

Option 4: "Enogen corn is specifically designed to enhance ethanol production."

Explanation: This option is correct as it directly reflects the text, which states that Enogen corn is designed specifically to enhance ethanol production. This aligns with the main idea of the text regarding the role of new technologies in improving ethanol production.

Option 1: "New technology is not creating any special earth-friendly ethanol."

Explanation: This option contradicts the text, which states that new technologies are making American ethanol more sustainable. The phrase 'not creating' directly opposes the information provided, making this option incorrect.

Option 2: "Ethanol plant helps to increase the viscosity."

Explanation: This statement is incorrect because the text indicates that the Enogen corn technology actually reduces the viscosity of the corn mash, not increases it. Therefore, this option misrepresents the information presented.

Option 3: "Helps to enhance efficiency and the cost."

Explanation: While the text mentions that the Enogen corn technology enhances production efficiency and decreases costs, this option is too vague and lacks specificity. It does not clearly connect to the specific technology mentioned, making it an incomplete representation of the text.
