The questions you asked are not very clear. In addition, this poem can also be understood in many ways. The two roads can be two work paths, two life directions, or even choices. Two different women. So I can only briefly talk about it from these two aspects.
1. The title is the guide for the entire poem.
2. There can be two jobs in front of you, or two women in front of you.
3. The less popular one may be because of the industry or because this woman is more innocent.
4. The theme is choice. There is no right or wrong. It is a pity not to choose. Maybe that is also a good way.
5. There can be many things, I guess it could be work or women.
6. The answer is the same as 4. Because you asked the same thing.
