What is the meaning of the word “associated” in the first paragraph?

  1. specialized
  2. predated
  3. connected
  4. obfuscated

Answer(s): C

Explanation:

In saying the two things are “associated,” the author intends to describe two ideas that are linked or intrinsically connected.





What is the major difference between matter at the nanoscale and matter at larger scales such as millimeters or inches?

  1. At the nanoscale, metals are bendable, and at larger scales they are rigid.
  2. Matter has different and special characteristics at the nanoscale.
  3. At the nanoscale, matter has the same properties as matter at the atomic level.
  4. There is no difference.

Answer(s): B

Explanation:

Nanotechnology is the science of studying very small pieces of matter. A nanometer is bigger than an atom, but smaller than a millimeter. The author explains that matter at the nanoscale and matter at larger scales both have different and special characteristics: "At the nanoscale, the physical, chemical, and biological properties of materials differ from the properties of matter either at smaller scales, such as atoms, or at larger scales that we use in everyday life such as millimeters or inches."





Which claim from the passage best describes the benefits of nanotechnology?

  1. Scientists can develop novel technologies and products.
  2. Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1 to 100 nanometers.
  3. The different colors can be used in simple medical tests to indicate infection or disease.
  4. Unique properties of materials emerge.

Answer(s): A

Explanation:

Nanotechnology is the science of studying very small particles of matter. The author states that it is a new field that may help scientists develop new technologies and products that will be helpful in industry and medicine as a result of the different ways that matter behaves at the nanoscale.





What is the author’s primary purpose in writing this essay?

  1. to explain how to utilize the nanoscale
  2. to review the conversion between the nanoscale and nanotechnology
  3. to advocate for the usage of more nanotechnology
  4. to describe nanotechnology and what it is

Answer(s): D

Explanation:

The overall tone of the passage is informational and fairly dry. The topic is nanotechnology and the paragraph explains in some detail what it is and what its value is.
