Question

Passage: The field of nanotechnology involves manipulating matter at the atomic and molecular scale to create new materials with unique propertiesNanotechnology has applications in medicine, electronics, and environmental scienceHowever, there are concerns about the potential health and environmental risks associated with the use of nanomaterials, which are not yet fully understood. What is one concern mentioned in the passage regarding the use of nanotechnology?

• A. Nanotechnology lacks applications in medicine
• B. Nanotechnology is too expensive to develop
• C. Nanotechnology may pose health and environmental risks
• D. Nanotechnology cannot create new materials
• E.

Hint:

When answering questions based on a passage, focus on explicit concerns or challenges mentioned by the author to identify the correct response

Answer 1

The Correct Option is C

The passage highlights several aspects of nanotechnology, including its wide-ranging applications in fields like medicine and electronicsDespite these benefits, it explicitly mentions concerns about the potential health and environmental risks posed by nanomaterialsThese risks are still not fully understood, making option (C) the correct choice
(A), (B), and (D) are incorrect because the passage states that nanotechnology does have applications in medicine, does not discuss cost concerns, and emphasizes its ability to create new materials with unique properties
