For chart-based command-of-evidence questions, translate the statement into a clear task (here, “highest average blood glucose” means “tallest bar”). Then compare the plotted values and choose the option that exactly matches the label of the data point that best supports the statement.
Hints
- Hint 1
Focus on the y-axis meaning
Check what quantity the y-axis represents and what a taller bar means.
- Hint 2
Look for the maximum value
Find the bar that reaches the highest point on the y-axis.
- Hint 3
Read the label under that bar
Use the x-axis label directly below the tallest bar to choose your answer.
Step-by-step
- Step 1
Identify what the chart measures
The y-axis shows average blood glucose (mg/dL) measured 30 minutes after each snack, so the highest bar corresponds to the highest average blood glucose.
- Step 2
Compare the bar heights
Scan the four bars and note which one reaches the greatest y-value (the tallest bar).
- Step 3
Match the tallest bar to its label
The tallest bar is labeled sports drink, so the snack associated with the highest average blood glucose level is the sports drink.
