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.
In fact, nanotechnology is used in the production of everything from toothpaste, sunscreens, and other cosmetics, to food packaging that
keeps its contents fresher, and clothes that are stain-resistant. An inventory in 2011 listed more than 1,300 products that contain nanoparticles,
and that list continues to grow each year. Its growth is so rapid there has not been enough time to study any negative impacts the technology
might pose. While the government and other interested groups are creating guidelines for nanotechnology development, regulations to protect
consumers and the environment are not yet in place. In the meantime, the study and use of nanotechnology continues to accelerate, yielding a
plethora of innovative products to improve modern-day living.
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, particularly 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.
