I'm taking a test and have to guess the right answer to the question after the article. Article: The first robot was invented in the 1920s. Robots have appeared in many American films. In some films, they are stronger, faster and cleverer than people. In real life, robots are mainly used in factories. They do some dangerous and difficult jobs for humans. Robots also help disabled people, for example, blind people. Today many blind people have a guide dog to help them. In the future, guide dogs might be robot dogs. One kind of robot guide dog has wheels. It moves in front of the owner. It is very clever. It knows the speed of its owner's walk. The owner wears a special belt. The belt sends instructions to the owner from the dog, such as "Stop here" "Turn left" or "Turn right". In the United States, another kind of robot helps disabled people to take care of themselves in their daily life. The robot hears the sound of its owner's voice. It follows instructions such as. "Turn the page" or "Make a cup of coffee". Robots are also used in American hospitals. They can do simple jobs. At one hospital, for example, a robot takes meals from the kitchen to patients' rooms. It never gets lost because this robot has a map of the hospital in its computer memory. Though robots can help people in many different ways, they will never take the place of humans. ,. Question: A robot guide dog _ . Options: A: goes in front of blind people B: walk side by side with blind people C: has a map in its head D: helps patients with their meals

I'm taking a test and have to guess the right answer to the question after the article. Article: Everyone dreams of changing the world. But can teenagers really make a difference? And how can they go about it? Michael Norton's book 365 Ways to Change the World is a good starting point. The book gives an idea or task for every single day of the year. The tasks include offering to work at a local homeless shelter and planting a tree. The book says that one simple act, no matter how small, can help someone in need. It may even influence other teens to do something. Nathan Anthony, a student at Maple High School in Modesto, California, US, agrees. "It is impossible to get anything in life without giving something to someone or working hard at school or workplace," Anthony said. Another Maple student, Ariane Mota, has the same idea." Giving is our way of repaying those who help us," she said." Whether it is a helping hand or a donation, we should help others to make their day or life better." But how often do teens see peers helping a stranger or doing something nice for someone? According to Anthony, not a lot. He and Mota both believe this needs to be changed. "I help my friends by telling them that their lives are better than those poorer people," Anthony said." Humor is also a great tool." So whether you're helping to find a cure for bad illness or simply smiling at a stranger, do something every day to help change the world for the better. Question: According to Nathan Anthony, how many teens can be seen helping a stranger or do something nice for someone? Options: A: a lot of teens B: Hundreds of teens C: Some teens D: Millions of teens

I'm taking a test and have to guess the right answer to the question after the article. Article: At one time or another we have all stopped to think about the weather. Some days the weather is good. Some days the weather is bad. Sometimes a day that seems bad turns out better than you thought it would. There are ways of understanding the weather. One way is to study the clouds. No two clouds are ever alike. We can see the different kinds of clouds and watch them for signs of changing weather. To forecast the weather, there are three things about clouds. you should look for: movement, colour, and change. As a rule, the higher the clouds, the better the weather. And the lower the clouds, the worse the weather is likely to be. Fair-weather cumulus clouds* are another sign of good weather. These are clouds we often see on warm summer days. Clouds can tell you if a storm is on the way. If the thick, fluffy cumulus clouds get bigger early in the day, then you know it will rain. If there is a sudden, cool and dark thunder* cloud appears, then a storm is about to break out. Colours in the sky tell us about the weather, too. A golden ring around the moon warns us that a storm is on the way. A watery yellow sunset is a sign that rain may be near. The rainbow* has a message, too. The colours of the rainbow come from the sun rays shining through falling rain. If you see the sun in the east and a rainbow in the west, the rain may be coming your way. If the sun is in the west and the rainbow is in the east, the rain will be moving away from you. Question: High clouds usually suggest _ . Options: A: bad weather B: fine weather C: rainy weather D: windy weather
