Universal symbols are designed for everyone, no matter where they are globally, to understand something. For example, a universal symbol could be the Red Cross, which symbolises health all over the world
<u>The proper answer to this question is "</u><span><u>kind of sign that is recognized by pretty much everyone".</u>
Reason:
<u>A universal sign would be like a peace sign. Everyone knows what it is and what it stands for (except for children) world peace. Universal signs are used to bring people together for a certain reason. Maybe a problem that was established a certain day of the year (probably a holiday) etc...
</u></span>Therefore the answer is a sign that everyone knows.
hmm u ask if you can talk about it probably apologize for what you said if say that you were out of it and weren't thinking something along the lines of that.
