Read the following article and answer the question. Article: Countries must learn to share water fairly if they are to prevent warring over water as population growth and climate change make it ever more scarce. Farming uses 70 percent of the fresh water taken from the world's lakes and rivers and need from farms is set to increase by 14 percent in the next 30 years. Water conflicts can happen in water-stressed areas among local communities and between countries. The lack of instruments for water sharing _ already difficult conditions. In the absence of clear rules, things will not be organized or arranged in order and power plays an important role. While humans drink between 2 and 5 litres of water a day, it takes 1,000-2,000 litres to produce a kilogram of wheat and up to 15,000 litres to produce a kilo of grain-fed beef. The daily consumption of water per person is a thousand times more than the consumption through drinking. Already 1.1 billion people lack clean water and, with the world's population set to grow from 6.5 billion to 8 billion by 2025, 1.8 billion people will face water scarcity by then. Global warming will exacerbate the problem, especially in poor, dry areas. To improve cross-border cooperation on water use, the 10 countries on the Nile are negotiating a water-sharing agreement which the Food and Agriculture Organisation hopes will be a model for other areas where the scarce water can be shared out peacefully. Question: What's the passage mainly about? Answer:
OPTIONS:
- Water conflicts can arise in poor and dry areas.
- Countries must learn to share water fairly.
- What caused water conflicts.
- Water consumption is increasing.

Answer: Countries must learn to share water fairly.

Read the following article and answer the question. Article: Celia was shocked. She had always been in good shape during high school, but now, in her first year of college, she was suddenly ten pounds heavier. "My friends and I often had pizza or ice cream when we studied late at night," she said, "and I was always drinking Coke to stay awake." Celia's experience is common. Many students enter college and find it so different that they cannot deal with changes properly. They're away from their parents and in a new stressful environment. Pressures together with freedom to sleep and eat however they please cause many students to experience the "Freshman 15": gaining weight suddenly in their freshman year of college. Most students do not realize that the "Freshman 15" can cause some serious health problems. Of course, college-age adults are still developing bone mass, so gaining some weight is normal. Sudden weight gain, however, puts too much strain on the heart and lungs, resulting in little energy and some difficulty thinking and remembering. In later life, it can lead to heart disease, diabetes, obesity, and possibly cancer. The solution to the "Freshman 15" is simple--pay attention to developing good habits! In general: * Eat normal-sized meals at regular times. Eat slowly and enjoy it, so you don't need to go back for more. * Keep only healthy snacks in your room--and don't snack too often! * Control drinking and smoking. Alcohol has a lot of calories, and smoking too much makes exercise difficult. * Exercise regularly! Even just 30 minutes a day--such as walking quickly to class from your dorm--will make a big difference! Question: What do most college students fail to realize? Answer:
OPTIONS:
- Gaining some weight is normal.
- They have grown up.
- They have gained a lot of weight.
- Sudden weight gain may lead to serious health problems.

Answer:
Sudden weight gain may lead to serious health problems.
