Read the passage below carefully, and then choose the best answer:
Have you ever noticed that our machines are getting smaller? Cell phones, cameras, computers and everything else look smaller every year. One kind of new science involves machines that are smaller than we can imagine. The name of this science is nanotechnology. Nanotechnology means doing science, engineering, and technology at a very very small level. In other words, nanotechnology is the science of tiny things. But how tiny is the science of nanotechnology? In nanotechnology, scientists work with things that are the size of a nanometer. One meter has one billion nanometers. Here is another way to describe nanotechnology: it is the science of observing and controlling individual atoms and molecules. Nanotechnology is a new word, but the idea of studying atoms and molecules has existed for a long time. In 1959, an American scientist Richard Phillips Feynman gave a speech in which he claimed that we can see and control molecules and atoms. About ten years later, a Japanese professor came up with the term “nanotechnology”. Because nanotechnology is so new, we are only starting to understand how we can use it. Nanotechnology could be very useful in medicine. In the future, doctors may use nanotechnology to help with organ transplants. An organ transplant is the act of putting an organ into another person’s body. Scientists think that with nanotechnology, they might be able to make a person’s body accept a foreign organ. Nanotechnology might also help doctors fight infections, find diseases in patients, and deliver medicine to the right spot in patients’ bodies. Nanotechnology might also be useful in protecting the environment. It might be able to help us save energy, reduce waste, and keep water clean. For example, nanotechnology might be able to make some materials such as steel stronger. If we have stronger steel, we will be able to use it longer. That way, we can produce less steel and save our resources. Nanotechnology might be useful in so many ways. This science of studying tiny things could change the world.
5. According to the passage, what will nanotechnology NOT do?
