Nanotechnology is the study and application of very, very small things-even smaller than what we usually think of as microscopic. For Instance, a human hair is between 80,000 and 100,000 nanometers in width. At this tiny scale, materials have many unique properties, such as less welght and greater strength. This new frontier of technology affects many Industries, from medicine and transportation to sports and entertainment. Its benefits are far-reaching. However, some feel that introducing this new technology could have unexpected consequences. Nanotechnology has the potential to transform daily life. Its use in medicine allows better Imaging for early diagnosis of diseases and other health problems. It also could provide the precise delivery of medicine to specific cells. Already many new cars have bumpers that can better resist dents, and electric cars have batteries that are cleaner and more efficient. In the coming years, sensors built into highways and bridges could help guide and improve the flow of traffic. Because of the new technology, baseball bats are more durable and resilient, tennis balls can bounce longer, and golf clubs can hit balls farther. Many new television and computer screens have brighter, clearer pictures. Nanotechnology offers many future benefits. Which statement provides an objective summary of the passage? 1. Nanotechnology applies to a wide range of industrial sectors, creating regulation problems for the government. 2. Nanotechnology brings unexpected changes to society, particülarly in the fields of medicine and transportation. O 3. Nanotechnology offers a chance to improve the quality of life, but the government intends to dramatically slow or halt its pace. 4. Nanotechnology presents an opportunity to create helpful products, but its development may be too quick to assess its risks.​
