Number 1 in what?
You may already know that I taught a course on testing and grading. The rather silly stuff I wrote yesterday was motivated by trying to think of ways that I was No. 1. Of course, we could list the weakest, lowest first and move to the highest, best last. But if I am the best speller in the class, I typically have to state the size of the class to establish how good I am, writing "I am the best speller in the entire third grade of 114 students!" It is easier and faster to rank them best first, so that Number 1 is the best and number 2 is second-best. With a spreadsheet or some other software, it is easy to sort various columns quickly and accurately. OpenAI says that 2 billion people use the free Google Sheets and 1.2 billion use Microsoft Excel for handling and analyzing numbers.
Because each human is unique and our situations are always changing, I think it can be fun to toy with the criteria for ranking. It may be easy for students to think that the teacher knows the "correct" answer to test questions but as we get more knowledge, sometimes we find that what was taken to be the "right" answer isn't correct. More often, I think as we proceed through our lives, we find that skills and abilities that were not called upon in school turn out to be valuable.
