31. The speaker says that one problem with nanotechnology is that
32. According to the speaker, some scientists believe that nano-particles
33. In the speaker's opinion, research into nanotechnology
The answer is C. The speaker mentions that 'with nanotechnology, society often gets the wrong idea about its capabilities.' This directly points out that one problem with nanotechnology is that it is misunderstood by the public, which matches option (C). Option (A) and (B) are both mentioned as fears or misunderstandings, but the main problem the speaker states is the general misunderstanding, not specific threats.

And with nanotechnology, society often gets the wrong idea about its capabilities.
The answer is B. The speaker says, 'Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and clear labelling,' and 'they believe that greater care should also be taken with nano-particles in laboratories and factories.' These statements show that some scientists think nano-particles should be handled more cautiously, which matches option (B).
