Let's analyze each statement based on the data provided in the table:
1. The United States uses more land to grow crops than to maintain forests.
- Crops: 408 million acres
- Forests: 671 million acres
To determine if this statement is true, compare the amount of land used for crops to the amount used for forests. Since 408 million acres (crops) is less than 671 million acres (forests), this statement is false.
2. The United States uses more land for parks and wildlife than for forests.
- Parks/Wildlife: 313 million acres
- Forests: 671 million acres
Compare the amount of land used for parks and wildlife to the amount used for forests. Since 313 million acres (parks/wildlife) is less than 671 million acres (forests), this statement is false.
3. The United States uses more land for parks and forests than for urban areas.
- Parks/Wildlife: 313 million acres
- Forests: 671 million acres
- Urban: 61 million acres
First, calculate the combined land for parks and forests:
[tex]\[
313\,\text{million acres (parks/wildlife)} + 671\,\text{million acres (forests)} = 984\,\text{million acres}
\][/tex]
Compare this combined amount to the land used for urban areas:
Since 984 million acres (parks + forests) is greater than 61 million acres (urban), this statement is true.
4. The United States uses more land for urban areas than for grasslands and ranges.
- Urban: 61 million acres
- Grass/Range: 614 million acres
Compare the amount of land used for urban areas to the amount used for grasslands and rangeland. Since 61 million acres (urban) is less than 614 million acres (grass/range), this statement is false.
Based on the data in the table, the true statement is:
- The United States uses more land for parks and forests than for urban areas.
So, the results for the statements are:
1. False
2. False
3. True
4. False
