Official Solution:
Drop-down 1:
• From the graph, we can easily see that the longest segment in each bar belongs to HVAC, making it the biggest energy consumer. Its consumption per month ranges from approximately 200 kWh to 300 kWh.
Drop-down 2
• Each HVAC segment, ranging from 200 to 300 kWh, is less than — or in some cases equal to — half of the corresponding bar height but well above 20%. Fortunately, the drop-down options are spread far enough apart that we don’t need to calculate precisely. We can safely choose 40% as the best estimate.
Correct answer:
Dropdown 1: "HVAC"
Dropdown 2: "40%"
