Many of the world's great cities are located on rivers, and almost every country has at least one river running through it that plays an important role in the lives of its people. Since the beginning of the history, people have used rivers for transportation . The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Gangs is great, but it is also important for transportation; Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation , however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it. Besides transportation, rivers give food, water to drink, water for crops , and chances for fun and entertainment for the people who live along their banks.

Write a multi-choice question for the following article, with the given choices and answer: Article: In the Caucasus region , nearly 50 out of every 100,000 people live to celebrate their 100thbirthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Caucasus people aren't alone. The Pakistani Hunzas, who live high in the Himalaya Mountains, and the Vilcabambans of the Andes Mountains in Ecuador seem to share the secret of long life too. These peoples remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasus people aged 110-140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked, "At what age does youth end?" most of these old people had no answer. Several replied, "Well, perhaps at age 80." The very youngest estimate was age 60. What accounts for this ability to survive (live) to such old age, and to survive so well? First of all, hard physical work is a way of life for all of these long-lived peoples. They began their long days of physical labor as children and never seem to stop. For example, Mr. Rustam is 142 years of age. He remembers his life experience: the Crimean War of 1854; the Turkish War of 1878; the Bolshevik Revolution in 1917. His wife is 116 years old. They have been married for 90 years. Mr. Rustam has no plan of retiring from his life as a farmer. "Why? What else would I do?" he asks. Oh, he's slowed down a bit. Now he might quit (stop working) for the day after 6 hours in the field instead of 10. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 5,000 to 12, 000 feet(1,660 to 4,000meters) above sea level. The air has less oxygen and is pollution-free. This reduced oxygen environment makes the heart and blood vessel system stronger. Another factor that may lead to the good health of these people is their isolation. To a great extent, they are separated from the... Options: A Cause and effect of long-lived life. B People in the world enjoying a longer life. C Factors leading to the health and long life of people. D A description of several societies where people living a long life. Answer: C Factors leading to the health and long life of people.
