Article: Most people go to a doctor in their own town or suburb . But people in the Australian _ can't get to a doctor quickly. The nearest doctor is sometimes hundreds of kilometers away so they have to call him on a two-way radio. This special doctor is called the "flying doctor". He visits sick people by plane. When someone is very sick, the doctor has to fly to the person's home. His plane lands on a flat piece of ground near the person's house. Sometimes the doctor has to take the patient to hospital. Flying doctors take about 8,600 people to hospital each year. However, most of the time the person isn't very sick, and the doctor doesn't have to visit. He can give advice on the radio from the office at the flying doctor center. He can tell the patient to use some medicine from a special medicine chest . There is one of these chests in every home in the outback. Each bottle, tube and packet in the chest has a number. The doctor often says something like this," take two tablets from bottle 5 every four hours."
Answer: the nearest doctor is sometimes very far away from them

Article: Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors. Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them. 1. What makes us human? Just looking at your DNA won't tell you - human DNA is 99 percent _ to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on - have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity for co-operation and our trading skills are what make us unique. 2. Why do we dream? Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream. Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain. 3. Could we someday live forever? Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes and cancer, are diseases of aging, treating aging itself could be the key to extending our lives. Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism , which are all leading to the invention of drugs that can slow down the aging process. If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered.
Answer: to explain what were once mysteries to our ancestors

Ex Output:
The main point of the passage is _ .

Ex Input:
Article: The journey to the moon had been the first step toward future exploration in space. The distance between the Moon and Earth is very short indeed when compared with the distances between Earth and the other planets. Mars, the nearest planet to Earth is millions of miles away. Traveling to the planets will be man's next aim. Such travels will be more challenging than the trip to the moon and certainly more adventurous. Recently, two American spaceships, Vikings 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither confirmed nor ruled out. Russians have discovered that the surface of Venus is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense and the pressure is nearly a hundred times greater than that of the Earth's atmosphere. Scientists believe man may find planets which have the same conditions as those we have on Earth , but man should realize Earth will be his only home for a long time and begin to love and care for it.
