Directions: In this part, there is one passage followed by a summary. Read the passage carefully and complete the summary with the maximum of three words from the passage. Remember to write the answers on the Answer Sheet. Questions 1 to 5 are based on the following passage. Bright colors stir up a range of feelings. For example, the color red can cause people to feel excited. In fact, red can even make a person feel hungrier. Yellow can increase energy. Therefore, a room with strong red and yellow colors would be a good place to eat a lot of food quickly. On the other hand, darker colors, like blue can help people calm down. A blue room can be a good place to study, since people can concentrate more easily. However, it is easier to nod off in a blue room than in a red one. The colors of clothes can also affect feelings. Black and dark blue clothes can produce a sense of strength and seriousness. Therefore, a person in a black suit can seem like a leader more easily than one wearing white. If a person is wearing a dark suit and a red tie, he may seem both powerful and energetic. This may be why many politicians and businessmen wear dark suits with red ties. Brown and green clothes can produce a sense of confidence. It may seem easier to trust a person wearing green. Therefore, many people wear green or brown for meetings or interviews.Choice of color, for rooms as well as clothes, is not only about appearance. Summary:
