Question 81·Easy·Command of Evidence
A biologist observed four bird species at the same backyard feeder and recorded the average number of feeder visits per hour for each species. The results are shown in the graph.
Based on the data in the graph, the species with the highest average number of feeder visits per hour was the ____. Which choice most effectively uses data from the graph to complete the statement?
For command-of-evidence questions that refer to a graph, first restate what the graph is measuring (what the y-axis represents). Then locate the specific evidence the question asks for (here, the greatest value) by comparing bar heights, and choose the option that exactly matches the labeled category for that data point.
Hints
Use the bar height
The correct choice is the species whose bar reaches the highest point on the y-axis.
Compare all four species
Check each bar’s height and note which one has the greatest average visits per hour.
Focus on the maximum value
Once you find the largest number on the graph, choose the species name directly below that bar.
Step-by-step Explanation
Identify what the graph measures
The y-axis shows the average number of feeder visits per hour, and each bar shows that average for one bird species.
Find the highest value
Look for the tallest bar (the greatest average visits per hour).
Match the tallest bar to its species
The tallest bar is for the black-capped chickadee, so the statement should be completed with black-capped chickadee.
