Question

all other things being equal, the larger a wind turbines rotor diameter (the diameter of the imaginary circle swept by the turbines rotating blades), the greater amount of energy the turbine can generate. in a research paper on wind power, a student claims that in the united states, the amount of energy generated per newly installed turbine increased substantially between 2011 and 2021. which choice best describes data in the graph that support the students claim? choose 1 answer: in 2011, nearly 80% of turbines installed had rotor diameters of less than 100 meters, whereas only a little more than 20% of turbines installed that year had rotor diameters of 100 - 115 meters. no turbines installed in 2011 had rotor diameters greater than 115 meters, whereas the majority of turbines installed in 2021 had rotor diameters greater than 130 meters. most turbines installed in 2011 had rotor diameters of less than 100 meters, whereas most turbines installed in 2021 had diameters of at least 115 meters. the percentage of newly installed turbines with rotor diameters

Explanation:

The claim is about the increase in energy - generating capacity due to larger rotor diameters of newly installed turbines from 2011 to 2021. Option C shows a shift from most turbines in 2011 having diameters less than 100 meters to most turbines in 2021 having diameters of at least 115 meters, indicating an increase in the proportion of turbines with larger diameters which can generate more energy.

Answer:

C. Most turbines installed in 2011 had rotor diameters of less than 100 meters, whereas most turbines installed in 2021 had diameters of at least 115 meters.
