These types of questions are generally discouraged on Puzzling.SE. There are a few major problems that occur when these questions are asked:
- They can generate answers which are only subjectively valid - that is, to some people, they appear valid, and to others, they do not. An answer is only correct or valid by one’s own opinion, and cannot be determined to be clearly and objectively correct.
- They can generate answers that are objectively questionable - for instance, depending on the country you are in, or a cultural background.
- They can generate answers that depend on different interpretations of the question. In this case, the question may be unclear, or the restrictions and conditions of the question may not be fully defined, which may be able to be fixed by making the puzzle more well-specified.
That being said, if a limited number of answers can objectively be proven to be correct, or are otherwise demonstrably correct, then the question is very likely on-topic. Watch out for questions which have an unbounded or large number of possible answers, as they may fit the above criteria.
If you feel that a question should be considered on-topic for this site, or are still unsure as to how this pertains to your question, feel free to ask here on Meta about your specific question. The community will give helpful feedback where we can!
