ELTIS English Language Test for International Students — VIP Practice Exam

Read the following passage and answer the question. "The global water crisis has emerged as one of the most pressing environmental challenges of the twenty-first century. Approximately 2.2 billion people worldwide lack access to safe drinking water, and the United Nations projects that by 2050, nearly half of the world's population could be living in areas facing severe water scarcity. The causes of this crisis are multifaceted, encompassing not only population growth but also agricultural demands, industrial pollution, and the accelerating effects of climate change. Agriculture accounts for roughly 70 percent of freshwater withdrawals globally, making it the single largest consumer of this vital resource. As temperatures rise due to greenhouse gas emissions, glaciers and snowpacks that supply rivers and aquifers are diminishing at unprecedented rates, further reducing the available freshwater supply. Addressing this crisis requires a combination of technological innovation, policy reform, and changes in individual consumption patterns. Water recycling technologies, desalination plants, and precision irrigation systems have shown promise, but their widespread implementation depends on substantial investment and international cooperation." What is the main purpose of this passage?
