- The table data lists US water usage categories: Irrigation (115,000), Industrial (15,900), Mining (5,320), Electricity production (161,000), and Farming aquatic organisms (9,420).
- Comparing the values shows that the statement 'More water was used to produce electricity than to grow crops' (\(161,000 > 115,000\)) is accurate.
- The statement 'More water was used to grow crops than to mine land resources' (\(115,000 > 5,320\)) is also accurate.
- The correct statements are: \(\boxed{\text{More water was used to produce electricity than to grow crops and more water was used to grow crops than to mine land resources.}}\)
Explanation
- Data and Category Identification
The problem asks us to evaluate four statements based on the provided table of US water usage in 2010. We identify the relevant categories for each statement:
- 'Grow crops' corresponds to the 'Irrigation' category: \(115,000\) million gallons/day.
- 'Make products' corresponds to the 'Industrial' category: \(15,900\) million gallons/day.
- 'Mine land resources' corresponds to the 'Mining' category: \(5,320\) million gallons/day.
- 'Produce electricity' corresponds to the 'Electricity production' category: \(161,000\) million gallons/day.
- 'Farm aquatic organisms' corresponds to the 'Farming of aquatic organisms' category: \(9,420\) million gallons/day.
- Evaluating the Statements
We now test each statement against the numerical data:
- Statement 1: 'More water was used to farm aquatic organisms (\(9,420\)) than to make products (\(15,900\))'.
Comparing the values, \(9,420 < 15,900\), so this statement is incorrect.
- Statement 2: 'More water was used to make products (\(15,900\)) than to produce electricity (\(161,000\))'.
Comparing the values, \(15,900 < 161,000\), so this statement is incorrect.
- Statement 3: 'More water was used to produce electricity (\(161,000\)) than to grow crops (\(115,000\))'.
Comparing the values, \(161,000 > 115,000\), so this statement is correct.
- Statement 4: 'More water was used to grow crops (\(115,000\)) than to mine land resources (\(5,320\))'.
Comparing the values, \(115,000 > 5,320\), so this statement is correct.
- Conclusion
Based on the comparisons, both statement 3 and statement 4 are supported by the provided data. Therefore, the statements 'More water was used to produce electricity than to grow crops' and 'More water was used to grow crops than to mine land resources' are both accurate summaries.
Examples
In environmental science or resource management, understanding how much water different sectors consume is crucial. For example, a city planner might analyze this data to decide where water conservation efforts should be focused. Knowing that electricity production and irrigation are the largest consumers helps prioritize policies, such as introducing more efficient irrigation technology or water-saving cooling systems in power plants, thereby ensuring sustainable resource management.
