Which choice most effectively uses data from the table to complete the statement?
For chart or table questions, first underline exactly what the question is asking for (here: region, category, and whether it wants the greatest or least value). Then, limit your attention to the correct column or row, list or mentally note the relevant numbers, and identify the maximum or minimum as needed before matching it back to the label. Avoid looking at extra parts of the table so you do not get distracted by irrelevant data.
Hints
Focus on the right region
Make sure you are only looking at the numbers under Region A (liters), not Region B.
Identify the largest number
Write down or underline the Region A values for all four activities and then decide which of those numbers is the greatest.
Connect the number to the activity
Once you know which number is greatest in Region A, look straight across that row to find the corresponding activity name.
Step-by-step Explanation
Locate the correct part of the table
The question asks about water use in Region A and wants to know which activity used the most water. Focus only on the Region A (liters) column and the activity names in the leftmost column.
Compare the Region A values
Read the values in the Region A column for each activity:
- Showers: 55 liters
- Laundry: 40 liters
- Toilets: 60 liters
- Faucets: 30 liters
Now compare these numbers to see which is the largest.
Match the largest value to the activity
The largest value in the Region A column is 60 liters. This value is in the row for Toilets, so the activity that used the most water on an average day in Region A was toilets.
