Need and Invention The Greek philosopher Plato said, "Need is the mother of invention." This means that when people have a need, they are motivated to create something to meet that need. For example, people needed a way to communicate over long distances, so they invented the telephone. They needed entertainment, so they invented the television. They needed to see in the dark, so they invented the light bulb. Inventions are often born from people's needs. Without needs, many great inventions might never have been created. So, the next time you face a problem, think about how you might solve it creatively. ( )1. What does "Need is the mother of invention" mean? A. Inventions are always useful. B. Needs motivate people to create inventions. C. Only great people can invent things. D. Inventions are made for fun. ( )2. What need led to the invention of the telephone? A. The need for entertainment. B. The need for light at night. C. The need for long-distance communication. D. The need for faster travel. ( )3.

Discovery and Invention Discovery and invention are two different concepts. A discovery is finding something that already exists but was not known before. For example, Christopher Columbus discovered America, but the land was already there. He just found it. An invention, on the other hand, is creating something that never existed before. Thomas Edison invented the light bulb, which did not exist before he made it. Discovery is about finding, while invention is about creating. Both are important for human progress. Discoveries help us understand the world, and inventions help us change it. ( )6. What is a discovery? A. Creating something new. B. Finding something that already exists. C. Making a new invention. D. Changing something old. ( )7. What is an invention? A. Finding something that exists. B. Creating something that never existed. C. Discovering a new land. D.

What does the passage say about both discovery and invention? A. They are both important for human progress. B. Discovery is more useful. C. Invention is more difficult. D. Neither is important. C. Using Rereading Strategy Rereading is a useful reading strategy. When you don't understand something, you should stop and reread certain parts. For example, if you read "He believed that machines were too slow to process images," you might ask, "What does 'process' mean here?" Then you can reread the sentence and think about the context. Rereading helps you understand the meaning better. It also helps you find answers to your questions. This strategy is especially helpful for understanding complex texts.
