Given below are two statements : Statement I : By 2025, two-thirds of world's people will be living in water stressed countries. Statement II : Growth of water withdrawal and consumption in Industrial sector is going to overtake that in Agriculture sector by 2025. In the light of the above statements, choose the correct answer from the options given below :
Statement I is true but Statement II is false
To determine the truthfulness of the given statements in the context of global water stress and industrial water consumption, let's analyze each statement individually:
Analysis of Statement I: "By 2025, two-thirds of the world's people will be living in water-stressed countries."
Analysis of Statement II: "Growth of water withdrawal and consumption in the Industrial sector is going to overtake that in the Agriculture sector by 2025."
Based on the analysis above:
Conclusion: The correct answer is: Statement I is true but Statement II is false.
