Read the following article and answer the question. Article: Real-life Friends Most people know the saying: A man's best friend is his dog; and that Diamonds are a girl's best friend. However, dogs can't offer advice or make you a cup of tea when you need one; and precious stones are cold comfort when you need a hug, and a shoulder to cry on. What are Friends? There are many ways to describe a friend. Friends are the family you can choose for yourself. Friends are a much better medication than medication is, and people who spend time with friends are happier with their lives as they are less lonely. A good friend will put you to bed when you're lost consciousness. Ensure you're not laid on your back, and remember to remove your shoes. You should be able to tell a true friend anything without being judged by them. How do Friendships Begin? This is an easy question. Find someone else who has similar interests with you. You now have another person to talk to about your shared interest but remember they like to talk too, so be prepared to shut up and listen once in a while. Hopefully they will have other friends and will introduce you to them, thereby expanding your circle. Friendships which begin due to location, for example, next-door neighbors or school classmates, rarely survive transitions such as moving to other neighborhoods, schools, colleges, jobs, immigration, and so forth. Attend a school reunion and you'll wonder what on earth you ever had in common with these people other than your age, although it is possible to have a friendship with someone you met at school. Mutually maintain it, and eventually become godparent or "uncle" to each others' children. How Friendships are Maintained To have a friend you must also be a friend and be prepared to be there for them should they need you. Failure in this respect would label you and you would most probably be abandoned. Boundaries Like every other relationship you have in your life, there are boundaries you shouldn't cross with your friends. One of those is money: Don't lend to your friend and don't ask for a loan... Question: The author brings in the topic by _ . Answer:

- giving negative examples
- raising a relative question

Read the following article and answer the question. Article: One day I was walking home along the street with my iPod on, when suddenly my headphones were knocked off my head and a man threw his arm around my neck, saying "Just be quiet." I was being attacked, and this man's arm was gripping onto me! I started screaming and tried to pull him off me, but failed. He was forcing me to walk towards the back of an auto repair shop and he just kept saying: "Be quiet." My mind froze with fear. Then I heard my great-grandmother's voice in my head. She was saying: "Come on now, I know you are stronger than that!" She was the rock in our family until she died four years ago. I have never had any self-defense training, but I went for it--I let out a loud scream as I kicked my leg back into his shin ! He let go of me and I ran off. When I looked back to see if he was running after me, I saw he was running in the opposite direction. Then I ran like crazy to a nearby drugstore. I asked the girl at the counter for the phone and called my mom. She picked me up five minutes later and I explained what happened through sobs. "I am calling the police!" She exclaimed. When we got home, two officers were waiting for us and I told them what had happened. After my experience, I was afraid to do anything. Things slowly got better, but I still don't like anyone going near my neck. The fear isn't totally gone--after all, the guy is still out there somewhere. But I had a new understanding of my own strength. I never expected to be able to fight off an attacker. I am stronger than I realized. Question: How did the author get rid of the man? Answer:

- Her loud scream scared the attacker and people came to help.
- Her great-grandmother's words gave her the strength to defend herself.

Answer: Her great-grandmother's words gave her the strength to defend herself.

Read the following article and answer the question. Article: With fifteen years prefix = st1 /Britainand other nations should be well on with the building of huge industrial complexes for the recycling of waste . The word rubbish could lose its meaning because everything which goes into the dumps would be made into something useful . Even the most dangerous and unpleasant wastes would provide energy if nothing else . The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out . The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city . This plant would recycle not only metal such as steel , lead and copper , but also paper and rubber as well . Another new project is being set up to discover the best ways of sorting and separating the rubbish . When this project is complete , the rubbish will be processed like this : First , it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed ; then it will pass through a powerful fan to separate the lightest elements from the heavy solids ; after that founders and rollers will break up everything that can be broken . Finally , the rubbish will pass under magnets , which will remove the bits of iron and steel ; the rubber and plastic will then be sorted out in the final stage . The first full-scale giant recycling plants are perhaps fifteen years away . Indeed , with the growing cost of transporting rubbish to more distant dumps , some big cities will be forced to build their own recycling plants before long . Question: The passage is mainly about_. Answer:
OPTIONS:
- a cheap way to get energy
- the location of recycling plants
- new ways of recycling wastes
- the probability of city environment

Answer:
new ways of recycling wastes
