Answer:
1. suppressing a fire at early stages
Step-by-step explanation:
If we talk about a crowd so we know that it is very difficult to convince all the people at once and there is a chance of a conflict arising. And avoiding the conflict in any society cannot be solved immediately because everything needs time. So if we start educating people at early stages then they will come to know about their manners and the way to treat others. Let the conflict be a fire and education be the education of the public. So suppressing a fire at early stages mean educating the public from their childhood so that they don't produce conflict in public.
