Question

look at the same graphs. think about how the population and the volume of fresh water withdrawn changed between 1980 and 2005.
u.s. population size
volume of fresh water withdrawn per year in the u.s.
groundwater other fresh water
data source: united states geological survey
select the statement that is supported by the data.
between 1980 and 2005, the population increased steadily, so more fresh water needed to be withdrawn over time.
between 1980 and 2005, the population increased steadily, but the total volume of fresh water withdrawn changed only slightly.

Explanation:

To solve this, we analyze the two graphs:

Step 1: Analyze the U.S. Population Size Graph

The line graph for population (1980–2005) shows a steady upward trend, meaning the population increased steadily.

Step 2: Analyze the Fresh Water Withdrawal Graph

The bar graph for fresh water withdrawal (1980–2005) shows the total volume (groundwater + other fresh water) changes very little—after 1980, the bars are roughly the same height.

Now, evaluate the statements:

• First statement: Claims “more fresh water needed to be withdrawn over time.” But the water withdrawal graph shows little change. Eliminate.
• Second statement: States “population increased steadily, but the total volume of fresh water withdrawn changed only slightly.” This matches both graphs.

The population graph (1980–2005) shows a steady increase. The fresh water withdrawal graph (1980–2005) shows the total volume (groundwater + other fresh water) has only slight changes (bars are roughly equal in height after 1980). The first statement’s claim of “more fresh water needed” contradicts the water withdrawal data, while the second statement aligns with both graphs.

Answer:

Between 1980 and 2005, the population increased steadily, but the total volume of fresh water withdrawn changed only slightly.
