When he saw it, he _ the cave entrance and stayed there, guarding it. From that day on, the man hid all his valuables in the cave, and to avoid anyone suspecting he was rich, he gave up his job, his home, and his friends. He constantly watched the approaches to his cave, wanting no one to find out about it. Fearing thieves, he guarded the cave all night long. He was so devoted to the cave that he hardly ate or drank. Before long, he fell ill. Many days passed, and he got thinner and sicker, losing all his strength. One day, when he could hardly move at all, he realized that it was his greed that had brought him to this extreme end. He understood that guarding his treasure had been of no use and no good. He decided to share it with others. He crawled into the cave to fetch some jewels, but discovered that the cave was almost empty. All he could find was a small emerald . He took it and left the cave, intending to give it to the first person passing by. Soon a woman approached and accepted the emerald with great joy. The man said to her, "I could have given you many more riches, but I don't know where they went. This is all I have now." "Are you sure there's nothing else?" replied the woman. The man shook his head and pointed to the cave. He found that some riches were still there; he saw some gold coins. He said, "Take them with you." The woman took both the emerald and the coins, and went away happily. In a while, an old man passed by and asked the man what he was doing there. The man replied, "What bad luck! Just a moment ago I gave a woman the few riches left over from the treasure I was guarding." "Are you sure there's nothing else?" The old man asked him. The man showed him the cave, and they found a box filled with jewels and gold. The man was shocked. The old man explained to him, "At last! At last someone has freed himself from the spell of this cave. You see, this is a...

Read the following article and select the best answer. Article: The "Neighborhood Watch" scheme all started a few years ago in the quiet village of Mollington after a number of burglaries in the village and the surrounding area. The villagers came up with the idea that they themselves could keep an eye on their neighbors' possessions while they were away on holiday. Since then, and with the support of the government and police, more than 50,000 "Neighborhood Watch" schemes have been set up all over the country. The object of each "Watch" group is to reduce the opportunities that criminals have in any particular street or area. Each villager who is a member of the scheme will call the police whenever they see something suspicious. It is the police who actually check out each report and look into what is happening. Villagers who are part of the "Watch" are not supposed to act as police or put themselves in danger. When a new "Neighborhood Watch" scheme is set up in an area, one benefit is that most burglars dare not take a chance on breaking into someone's house because they know that there is a high risk of being seen by neighbors keeping a lookout. Burglars also know that people are more likely to have fitted good locks to their doors and windows. Another benefit is that, since the "Neighborhood Watch" schemes came into existence, there is growing evidence of a new community spirit. It is bringing people together as never before, and encouraging people to care for each other. New friendships are being made, and contact is often established with old people living on their own, who are often the most frightened and the most at risk. Question: Another benefit of the "Watch" schemes is that _ . - a new community spirit is growing - old people are no longer frightened of crime - members of the "Watch" look after old people - different kinds of people are attracted to live in the area
a new community spirit is growing

Read the following article and select the best answer. Article: As the population grows and temperatures rise, it will become more difficult to grow enough food for everyone. So, scientists are exploring the planet for plants that do not need as much water as today's crops. The Mojave Desert in the US state of California is home to some of these plants. Scientist Heather Rose Kates of the University of Florida is in that desert. She is searching along roads for a plant called coyote melon which is a kind of squash .Coyote melon may not taste good, but it can be grown in places that have little rainfall. The desert where it grows gets just 15 to 20 centimeters of rain per year, or less. Other kinds of squash need at least two and a half centimeters per week to grow. Scientists are considering combining wild coyote melon with regular squash to see if they can make a tasty vegetable that doesn't need as much water to grow. That could be useful on a planet growing warmer and more crowded every day. Andy Jarvis works at the International Center for Tropical Agriculture. He says farmers will need to produce 50 to 70 percent more food by 2050 to feed the world. So, he says, researchers are studying the wild versions of farm-grown crops. But he says there is a problem. He says many wild versions of farmed plants are disappearing. He says they are threatened and scientists have not collected their seeds for future use. Scientist Kates is part of an international effort to gather these plants and save their seeds while it is still possible. Workers are collecting wild potatoes in Argentina and wild peppers in Para-guav. The plants and seeds will be sent for storage to the Global Seed Vault in Norwav and at Kew gardens in Britain. Ms Kates spends most of her time in a laboratory. She says gathering plants has helped her understand more about them. Question: Why do scientists study coyote melon? - It tastes good. - It is easy to cook. - It only needs little water to grow. - It is welcomed by many American people.
It only needs little water to grow.
