Almost 50 percent of water withdrawn in the US, is used up by thermoelectric power plants. The table below shows the amount of water withdrawn in the U. S., in billion gallons per year, between 1950 and 2005.

Year Amount of water withdrawn in the US (in billion gallons per year)

1950 180

1965 340

1975 420

1990 410

2005 410

Based on the table, which of these conclusions is most likely correct?

The number of thermal power plants decreased between 1950 and 1975.

The number of thermal power plants increased between 1950 and 1975.

Thermoelectric power plants used very little water between 1975 and 2005.

Thermoelectric power plants produced very little energy between 1975 and 2005.

Thermoelectric power plants used very little water between 1975 and 2005.

The number of thermal power plants increased between 1950 and 1975.

Explanation:

Here, the table that shows the amount of water withdrawn in billion gallons per year, between 1950 and 2005,

Year 1950 1965 1975 1990 2005

Amount 180 340 420 410 410

Since, 420 > 180,

Also, 50 percent of water withdrawn is used up by thermometric power plants.

Thus, thermal power plants in 1975 > thermal power plant in 1950

Therefore, the number of thermal power plants increased between 1950 and 1975.

Second option is correct.

Note : first option is incorrect.

Since, by the above table,

The least amount of water used by power plant is 180 billion gallons per year,

Thus, third option is incorrect,

Now, the table does not represents energy produced,

Fourth option can not be said correct.
