Article: prefix = st1 /Gland, Switzerland - Rivers on every continent are drying out, threatening severe water shortages, according to a new WWF report. The report, World's Top Rivers at Risk, released ahead of World Water Day (22 March), lists the top ten rivers that are fast dying as a result of climate change, pollution and dams. "All the rivers in the report symbolize the current freshwater crisis, which we have been signalling for years," says WWF Global Freshwater Programme Director Jamie Pittock. "Poor planning and inadequate protection of natural areas mean we can no longer assume that water will flow forever.

Dams along the Danube River -- one of the longest flowing rivers in Europe -- have already destroyed 80 per cent of the river basin's wetlands and floodplains. Even without warmer temperatures threatening to melt Himalayan glaciers, the IndusRiverfaces scarcity due to over-extraction for agriculture. Fish populations, the main source of protein and overall life support systems for hundreds of thousands of communities worldwide, are also being threatened. The report calls on governments to better protect river flows and water allocations in order to safeguard habitats and people's livelihoods. "Conservation of rivers and wetlands must be seen as part and parcel of national security, health and economic success," Pittock adds. "Emphasis must be given to exploring ways of using water for crops and products that do not use more water than necessary." In addition, cooperative agreements for managing shared resources, such as the UN Watercourses Convention, must be ratified and given... Question: We can easily learn from the passage that _ .

Read the following article and answer the question. Article: People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular. Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person's breathing muscles. Smokers usually take in small amounts that the body can quickly break down. Nicotine can make new smokers feel dizzy or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers' risk of heart disease and stroke. Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases. Question: What's the main idea of this passage? Answer:
OPTIONS:
- Where did cigarettes come from?
- The effect of smoking on your body.
