It's really not like a magical saying or phrase that is going to get a women to give you some sincere emotional response. It's actually more about you, than her.
Think about it. If you are just like any other random guy, that doesn't have much going for you, chances are your questions will be more scripted, or can even give off a "cold" feeling because you are sounding a robot spitting them out. It's hard to really put much into a question/comment when any topic aside from drinking and fantasy football is boring to you.
If you have strong goals, you know exactly what you want, you have confidence in yourself, and you can genuinely present yourself in that way, your conversations with women are going to connect with them more on an emotional level. Your own emotion on a topic will be seen when you ask her, and that is going to trigger the same response from her.
This is actually a huge topic that I'm surprised doesn't get more mention here. That may be because it closely connects to the main point so many posters (and this site in general) preach. Improve yourself and the rest will fall into place. There is no magic switch to flip to get an emotional response from a woman (aside from individual cases where a certain topic really hits home for some random woman). By becoming more interesting yourself and having more substance in your life, this will be a natural change.
