Practice Reading: Multiple Choice, Single Answer ID: #50242 Less Water
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
California grape growers in coastal areas can use less water during times of drought and cut irrigation levels without affecting crop yields or quality, according to a new study out of the University of California, Davis. Researchers focused on crop evapotranspiration, which was the amount of water lost to the atmosphere from the vineyard system based on canopy size. The weekly tests used irrigation to replace 25%, 50% and 100% of what had been lost by the crop to evapotranspiration. And they found that vineyards can use 50% of the irrigation water normally used by grape crops without compromising flavor, color and sugar content.

How much irrigation water is the most beneficial in maintaining the grape’s flavor profile and yield according to the research?

Option 3: "50%"

Explanation: The text explicitly states that vineyards can use 50% of the irrigation water normally used without compromising flavor, color, and sugar content, making it the most beneficial level for maintaining grape quality.

Option 1: "25%"

Explanation: The text states that the researchers tested irrigation levels of 25%, 50%, and 100%, but it does not indicate that 25% is beneficial for maintaining flavor or yield. Instead, it suggests that 50% is the level that does not compromise quality.

Option 2: "30%"

Explanation: The text does not mention 30% at all. Therefore, it cannot be considered beneficial for maintaining flavor or yield, as it is not part of the tested irrigation levels.

Option 4: "100%"

Explanation: While 100% irrigation is mentioned, the study indicates that using this amount is not necessary and does not provide any additional benefits for flavor or yield compared to using 50%.
