Which choice most effectively uses data from the table to complete the statement?
For table questions that ask for the greatest or least value, focus immediately on the relevant numeric column, scan all the values to find the extreme (smallest or largest), and then match that value back to its row label. Avoid doing any unnecessary calculations—simple comparison is enough—and double-check that you are answering "least" vs. "most" correctly.
Hints
Focus on the right column
Ignore the day names at first and look only at the numbers in the "Electricity used" column. What does "least" tell you to look for among these numbers?
Identify the smallest value
Write down or mentally list the four numbers: 28, 31, 29, and 27. Which one is the smallest?
Connect the number back to the day
Once you know which number is smallest, check the table to see which day has that value in the "Electricity used" column.
Step-by-step Explanation
Interpret the question
The question asks for the day when the household used the least electricity. "Least" means the smallest number in the "Electricity used" column of the table.
Compare the electricity amounts
Look at the "Electricity used" values for each day:
- Monday: 28
- Tuesday: 31
- Wednesday: 29
- Thursday: 27
Now, decide which of these numbers is the smallest. The numbers in order from smallest to largest are: 27, 28, 29, 31.
Match the smallest number to the day
The smallest number is 27. From the table, 27 kWh corresponds to Thursday, so the household used the least electricity on Thursday.
