If five users with at least 3k reputation vote to close a question, it gets closed with the closing reason chosen by the majority appearing as the official closing reason. There are five possible reasons for closing at MSE. So I'm curious what happens if there is no majority reason. What happens with the vote tallys 2:2:1, 2:1:1:1 and 1:1:1:1:1?
See https://meta.stackexchange.com/a/10583/151385 for the details on Meta.SO. It states
What if multiple close reasons are used on a question?
If a moderator participates in the closure, the reason the moderator selects is displayed. Otherwise, the question gets closed with the most frequently given reason. If there is a tie, the latest reason is used. However, if multiple potential duplicates were suggested, all of them will be displayed in the automatically generated "possible duplicates" box.
