Question: Read the following article and answer the question. Article: Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world. So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls ? Why don't we use them for collecting energy? The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work? The Solar Road Panels will contain embedded LEDs which "paint" the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour ahead. The road will be able to sense wildlife on the road and can warn drivers to "slow down". There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving. Replacing asphalt roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips. We just can't wait to see more of these roads all over the world in the near future. Question: What is the text mainly about? Answer:
OPTIONS:
- Functions of the road in the future.
- Development of solar energy.
- Free energy on the road.
- Solar road of the future.
Answer: Solar road of the future.

Question: Read the following article and answer the question. Article: When school was out, I hurried to find my sister and get out of the schoolyard before seeing anybody in my class. But Barbara and her friends had beaten us to the playground entrance and they seemed to be waiting for us. Barbara said, "So now you' re in the A class. " She sounded impressed. "What' s the A class? "I asked. Everybody made superior yet faintly envious giggling sounds. "Well, why did you think the teacher moved you to the front of the room, Dopey? Didn' t you know you were in the C class before, way in the back of the room? " Of course I hadn' t known. The Wenatchee fifth grade was bigger than my whole school which had been in North Dakota, and the idea of subdivisions within a grade had never occurred to me. The subdividing for the first marking period had been done before I came to the school, and I had never, in the six weeks I' d been there, talked to anyone long enough to find out about the A, B, and C classes. I still could not understand why that had made such a difference to Barbara and her friends. I didn' t yet know that it was shameful and dirty to be a transient laborer and ridiculous to be from North Dakota. I thought living in a tent was more fun than living in a house. I didn' t know that we were gypsies, really (how that thought would have excited me then! ), and that we were regarded with the suspicion felt by those who plant toward those who do not plant. It didn' t occur to me that we were all looked upon as one more of the untrustworthy natural phenomena, drifting here and there like mists or winds, I didn' t know that I was the only child who had camped on the Baumann' s land ever to get out of the C class. I didn' t know that school administrators and civic leaders held conferences to talk about the problem of transient laborers. I only knew that for two happy days I walked to school with Barbara and her friends, played hopscotch and jumped rope with them at class intervals, and was even invited into the house for some ginger ale--a strange drink I had... Question: Immediately after the narrator was moved to the A class, what was the attitude of Barbara and Barbara' s friends towards her? Answer:
OPTIONS:
- Dislike
- Jealousy
- Apology
- Acceptance
Answer: Jealousy

Question: Read the following article and answer the question. Article: We each have a unique genetic (,) make-up. Every cell of your body has the same set of about 100,000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion combinations of DNA which come from the random mixing of your parents' genes. Except for identical twins , no one has the same combination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make. But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births---some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters. Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins. Scientists are trying to identify the different genes that influence our behaviour. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take... Question: Why are scientists studying twins? Answer:
OPTIONS:
- To find out how many twins are born every year.
- To discover what shapes us as individuals.
- To compare differences between twins.
- To study brother-and-sister relationships.
Answer:
To discover what shapes us as individuals.
