The question What kinds of places in Singapore require visitors to present their physical passport? was closed because it is a list question. However, from my understanding What qualifies as a "list" question and what doesn't?, if the question is well-defined and that there is a reasonably small number of possible answers, then the question shouldn't be closed as a list question.
As the answer to the question What kinds of places in Singapore require visitors to present their physical passport? shows, there are only about 4 such kinds of places (accommodations, medical, massage, places serving alcohol). I believe that qualified as a reasonably small number of possible answers. By comparison, to take another recent question, Which currencies are accepted for the visa on arrival in Laos, and what is the price in each currency? likely has 3 answers and was well received. And there are many questions with much larger list that were well received and not closed, e.g.:
- When and why do people clap/applaud after a plane lands?
- Why would you wrap your luggage in plastic?
- How to make dining alone less awkward?
- Where in the world can I travel with a COVID vaccine passport?
- Where can I take a selfie with kangaroos in Australia?
- Where can I find publicly accessible paternoster elevators?
- Where can I go to avoid planes overhead?
- (Where) Can I go to a "sleeper" cinema?
- Where can I see the Milky Way in Europe?
- Are Ginkgo trees in Japan rare and if so, where can I find them?
