Question: Article: Color is very important in our daily life. It can influence our choice of purchase when we go shopping and can also affect the way we look and feel. A person can be naturally attracted to one particular color1 while finding another color1 repulsive. The influence of color1 on human emotions and feelings is very powerful and designers, advertisers, artists and even doctors use  _ in their professions for different purposes. Every day, without even thinking about it, we use color1 to communicate our feelings. For example, the color1 we choose to wear is one way of expressing ourselves. It says something about the person, how he or she feels, and how he or she wants others to feel about the wearer. In other words, color1 talks. A person who wants to appear stylish and mature will usually wear dark color1s or black. A person who wishes to appear youngish, pure and innocent dresses in white, like the choice of a bride's wedding gown. Also clothed in white are doctors, dentists, nurses and hospital in-patients as the color1 expresses comfort, cleanliness and professionalism. Brown, blue or grey clothes are the usual color1s worn by office workers so as not to draw unnecessary attention to them. They are, in a way, conveying the message that they want to be noticed for their work, not their appearance. People who wear bright, strong color1s like to be attractive and these color1s are particularly popular with actresses, singers and party goers. In the past, common people were not allowed to wear certain color1s. In Thailand, for example, only kings, queens and members of the royal family could wear purple while in ancient China, yellow was the color1 reserved for the emperor and the empress. Nowadays, people can wear whatever color1 they like or as they think appropriate.

Question: Article: Late that afternoon I took the train back to Sydney . There I found another surprise waiting for me . My room at the hotel had been given to somebody else and they had no room for me. Harkin had known my travel plans and had planned everything . How could he have booked the room only for three days ? There was nothing to be done but to find another hotel. The waiters were happy to find me a new hotel , and when I said that I was happy to stay at the airport , thinking it might be cheaper than staying in the city , they suggested the Holiday Inn at the airport . There was one small matter : the room rate was $ 300 per night . The best hotel in Katoomba had wanted only $ 145 . I asked if there was anything cheaper they might suggest but they warned that most hotels would already be full by this time. The hotel was far from the train station , so I had to take a taxi , at $ 25 . On the way to the Holiday Inn , we passed a hotel just two blocks from the Holiday Inn that advertised a room rate of $ 104 . At the desk I asked if their room rate could go down a lot . " No , this is a 4-star hotel," the waiter told me . " In that case ," I replied , " I'll just walk the two blocks to the cheap hotel." But she warned me that they were probably full and that if I didn't take the room , it might not be available when I came back . Finally , I decided to take the room. The room itself was big , but the air conditioning couldn't keep up with the Australian heat . I couldn't sleep until about 1:00 am.
