Nanotechnology is a field of research that involves manipulating materials at the atomic or molecular level to achieve remarkable properties and functionalities. Recently, it has been discovered that certain nanoparticles used in consumer products can accumulate in the human body and cause adverse health effects. Supporters of nanotechnology argue that these concerns are overblown and that the benefits of nanotechnology, such as improved drug delivery and environmental cleanup, far outweigh the risks.
Which of the following, if true, most strengthens the argument of the supporters of nanotechnology?The supporters argue that the risks of nanotechnology are overstated and that the benefits are greater than the risks.
The best strengthener should show that nanotechnology produces major real benefits, especially benefits strong enough to outweigh
possible health concerns.
(A) The majority of nanoparticles used in consumer products do not have the ability to penetrate human skin.
This helps a little because it reduces one possible risk. But the concern is about nanoparticles accumulating in the human body, and this answer addresses only skin penetration.
(B) Recent studies have shown that the accumulation of nanoparticles in the body can be effectively monitored and regulated.
This helps by showing that the risk can be controlled. But it does not directly show that the benefits outweigh the risks.
(C) The health benefits of drug delivery systems using nanotechnology have significantly improved patient outcomes in clinical trials.
This is correct. It gives direct evidence that nanotechnology has produced significant medical benefits. That strongly supports the claim that its benefits can outweigh its risks.
(D) Fewer adverse health effects have been reported in countries that have implemented strict regulations on the use of nanoparticles.
This shows that regulation may reduce harm, but it does not directly support the broader claim that nanotechnology’s benefits outweigh its risks.
(E) Advances in nanotechnology are projected to reduce the cost of manufacturing environmentally friendly products in the next decade.
This gives a possible future benefit, but it is only a projection and is less direct than actual improved patient outcomes.
Answer: (C)
