EXHAUSTIVE:

A． indicate some possible technological benefits to the development of new and varied techniques in nanotechnology
B． argue that science involving the macroscopic tends to be exponentially more difficult than the science of the microscopic
C． defend the use of the bottom-up approach of building molecules as more efficient relative to the top-down approach
D． distinguish two different approaches in nanotechnology and comment on their differences and similarities
E． correct the misconception that the benefits of nanotechnology are likely to be seen in the near future

A． Nanotechnology research tends to be more focused on the process of building multiple molecules than chemistry research.
B． Nanotechnology research is increasingly less bound to operations on the microscopic level than it once was.
C． The practitioners of nanotechnology tend to be more optimistic than pragmatic in choosing its methodology.
D． Nanotechnology research involves a much greater level of technical knowledge, on the whole, than chemistry research.
E． Nanotechnology research tends to be more concerned at this stage with precision than convenient mass production.
