An environmental report notes, “The smallest households use roughly 80 gallons of water per day.” According to the table, this amount of water is typically used by households with ____.
Which choice most accurately completes the statement using information from the table?
For table-based evidence questions, first restate what the question is looking for in simple terms (for example, “household size that uses about 80 gallons”). Then, go directly to the relevant column in the table, find the number or range mentioned, and read across to identify the matching category. Always rely on exact values from the table rather than choosing based on what “seems” small or large, and double-check that your choice answers the specific wording of the question.
Hints
Focus on the key number
The report mentions households that use roughly 80 gallons of water per day. Look for this number in the table.
Connect the number to household size
Once you find 80 in the water use column, check the number of people in household for that same row.
Use exact matches from the table
The report says “roughly 80 gallons,” and the table shows an exact value of 80 gallons. Use the household size from that row to choose your answer.
Step-by-step Explanation
Understand the statement from the report
The report says, “The smallest households use roughly 80 gallons of water per day.” That tells you two key things:
- It is talking about the smallest households (households with the fewest people).
- Those households use about 80 gallons of water per day.
Locate 80 gallons in the table
Look at the right-hand column of the table, labeled Average daily water use (gallons).
- Scan down until you find the value 80.
- Notice which row contains 80 gallons, then look across to see how many people are in that household.
Match the table to the statement and choose the answer
In the table, 80 gallons corresponds to a household with 1 person. So, the statement “The smallest households use roughly 80 gallons of water per day” is talking about households with 1 person, which is the correct completion.
