Write a multi-choice question for the following article: Article: Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world's population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn't have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy.

Write a multi-choice question for the following article: Article: Many things -- genetics, environment, the food you eat, illness, sleep, even the seasons -- influence your emotional state. But at the heart of it is how you regard yourself. If you have a healthy level of self-esteem, you not only cope with life's challenges better than people with low self-esteem, but you're probably more content, confident, and successful. You're probably also healthier. Studies show that positive self-esteem actually helps inoculate (......) people against depression and anxiety, conditions that may present increased risk of everything from colds to heart diseases. Most people's good sense of worth is rooted in their childhood -- in the early approval of their parents, teachers, and friends. But as we get older, most of us judge ourselves by our sense of how effectively we're managing in the world, especially in the areas of love and work. Our ability to love and to be loved can give us a sense of purpose and deep fulfillment. We can also find satisfaction and pride in work-related accomplishments and the people we meet and work with can reinforce our sense of self and our role in life. Once midlife comes along, however, our self-esteem can take a turn in response to changes in our lives. Marital relationship may change, children may leave home , and we may begin to scale back our work as we approach retirement. Of course, the view in the mirror may not be what it used to be, either. If you find your self-esteem eroding a bit, try to build it up again. As the saying goes, it's better to try something and fail than to be successful at not trying anything . Focus on goals that are linked to activities you're really interested in, so you'll enjoy a sense of purpose and gain pleasure from the pursuit whether or not you achieve your goal in full.
