[单项选择]You’ve probably had the experience of having someone fall in love with you when you didn’t feel the same way. In such a case it’s hard to know what to do. You don’t want to be so obvious in your efforts that you make an enemy of him.

And as awareness of nanotechnology grows, they will begin to understand that it covers a range of different ways of doing things, some of which carry some risk and others do not.
