Q: Read the following article and answer the question. Article: In the earliest stages of man's development he had no more need of money than animals have. He was content with very simple forms of shelter, made his own rough tools and weapons and could provide food and clothing for himself and his family from natural materials around him. As he became more civilized, however, he began to want better shelter, more efficient tools and weapons, and more comfortable and more lasting clothing than could be provided by his own neighborhood or by the work of his own unskilled hands. For these things he had to turn to the skilled people such as smiths, leather workers or carpenters. It was then that the question of payment arose. At first he got what he wanted by a simple process of exchange. The smith who had not the time to look after land or cattle was glad to take meat or grain from the farmer in exchange for an axe or a plough . But as more and more goods which had no fixed exchange value came on the market, exchange became too complicated to be satisfactory. Another problem arose when those who made things wanted to get stocks of wood or leather, or iron, but had nothing to offer in exchange until their finished goods were ready. Thus the difficulties of exchange led by degree to the invention of money. In some countries easily handled things like seeds or shells were given a certain value and farmer, instead of paying the smith for a new axe by giving him some meat or grain, gave him so many shells. If the smith had any shells left when he had bought his food, he could get stocks of the raw materials of his trade. In some countries quite large things such as cows or camels or even big flat stones were used for trade. Later, pieces of metal, bearing values according to the rarity of the metal and the size of the pieces, or coins were used. Money as we know it had arrived. Question: As men became more civilized they _ . Answer: | OPTIONS:
- all learnt to make by themselves the things needed
- had to travel a lot to look for what they wanted
- wanted better things than those they themselves could provide
- no longer provided food and clothing for themselves

Q: Read the following article and answer the question. Article: When Regis Mngwiro and the other villagers moved to a new place in southeastern Zimbabwe, Africa, they were happy to find a lake nearby. Now, they would no longer have to walk long distances looking for water. At last, they had a source of water what they call their own. But several days later, two young boys saw something they had never seen before--a huge animal was standing at the edge of the lake, eating grass. When the animal saw the boys, it walked into the lake and disappeared beneath the water. Regis looked into the story of the big creature that vanished into to the lake. "When I took a closer look at the dung , I realized that it was from a hippo ," he said. Twelve hippos were living in the lake. The villagers were worried. In the countrry of Zimbabwe, hippos attack humans more often than lions do. The hippos would often stay on the village side of the lake all day. This meant that the villagers could not go near the lake until the hippos got out. It was too long a wait for the villagers, because they needed the water from the lake to survive . "This is the only source of fresh water in the village," said a villager. "There is no way we can avoid this lake." So the women began moving in groups whenever they went to get water from the lake. Before collecting water, they made sure no hippos were nearby. The men began fishing in pairs, with one man always looking out for hippos. It took time, but these days, the hippos and humans live side by side. The villagers say that when the hippos find people coming, they swim slowly to the other side of the lake and mind their own business. The villagers do not go into the part of the lake where the hippos usually stay. They have learned to share the lake they both need to survive. Question: Before Regis and other villagers moved to the new place, _ . Answer: | OPTIONS:
- Regis had never heard of hippos
- they had their own source of water
