Question 151·Easy·Command of Evidence
In a greenhouse experiment, researchers grew four varieties of tomato seedlings under the same light and watering conditions. After six weeks, the researchers recorded the average height of the seedlings in each variety. The results are shown in the figure.
The researchers concluded that the variety with the greatest average height after six weeks was the ____
Which choice most effectively uses data from the figure to complete the statement?
For command-of-evidence questions with a figure, restate what the sentence is asking for (here, the greatest average height), then go straight to the relevant feature in the visual (the tallest bar). Finally, choose the option that exactly matches the label tied to that data point, without adding information that is not shown.
Hints
Focus on the conclusion
The blank refers to the variety with the greatest average height after six weeks.
Use the bars as evidence
Look for the tallest bar in the figure, since a taller bar means a greater average height.
Check the label under that bar
Read the variety name directly below the tallest bar on the x-axis.
Step-by-step Explanation
Identify what the figure measures
The bars show the average height after six weeks for each tomato variety.
Find the tallest bar
Compare the four bar heights and locate the one with the greatest value.
Match the tallest bar to the variety
The tallest bar corresponds to the Heirloom tomato, so that variety had the greatest average height after six weeks.
