Question

a source of freshwater
1 turning salt water into freshwater may seem like magic. but its not. many countries do it. today, few people do this to meet their water needs. but by 2025, 14 percent of us will lack freshwater. we will have to make more freshwater. so, desalination has a strong future.
2 desalination removes salt from water to make freshwater. people learned how to do this long ago. aristotle wrote about it in 320 bce. sailors turned salt water into drinking water in the 1770s. then methods got better during world war ii. soldiers in the desert needed water. in the 1950s, people found new ways to filter seawater. by the 1990s, many cities were making freshwater from the sea.
3 in the last 10 years, the use of desalination has grown. the largest projects are in saudi arabia, australia, algeria, and israel. in california, a new plant will soon serve the people of san diego.
according to the passage, why is desalination \a solution for the future\?
○ desalination plants are easy to build.
○ there is a large desalination plant in california.
○ people have been conserving water for a long time.
○ more places around the world are running out of freshwater.

Explanation:

To determine why desalination is "a solution for the future", we analyze the passage and options:

• The passage states "by 2025, 14 percent of us will lack freshwater. We will have to make more freshwater. So, desalination has a strong future." This connects to the idea that more places are running out of freshwater, making desalination a future solution.
• The other options are incorrect: There's no mention that desalination plants are easy to build (first option). The existence of a plant in California (second option) is an example, not a reason for it being a future solution. Water conservation (third option) isn't related to why desalination is a future solution.

Answer:

D. More places around the world are running out of freshwater.
