Question

since 1950, the united states geological survey (usgs) has tracked the volume of fresh water used in the united states. the graph below shows the volume of fresh water withdrawn, or taken by humans for any use, in a given year. the data were collected every five years, starting in 1950 and ending in 2005.
volume of fresh water withdrawn
per year in the u.s.

data source: united states geological survey
select the statement that is supported by the data.
the volume of fresh water withdrawn per year
increased every five years between 1950 and 2005.
the volume of fresh water withdrawn per year
increased steadily until 1980.

Explanation:

To determine the correct statement, we analyze the bar graph:

• For the first statement: From 1980 to 1985, the volume of water withdrawn decreases (the bar for 1985 is shorter than 1980), so it does not increase every five years.
• For the second statement: From 1950 to 1980, each subsequent bar (every five years) is taller than the previous one, showing a steady increase in the volume of fresh water withdrawn per year until 1980.

Answer:

The volume of fresh water withdrawn per year increased steadily until 1980.
