Atemporary gathering of people who are in close enough proximity to interact. crowd panic public moral panic mass hysteria mob fad

The answer is Crowd :DD

   Crowd

Explanation:  Every gathering of people who are close enough to communicate without some established rules or without any organization is a crowd.

Panic is a sudden fear due to an unexpected event or attack, and the reaction is a ruthless and spontaneous behavior to avoid a threat.

The public implies all people and their behavior, thinking, but not in some sudden and unforeseen situations, but usually.

Moral panic occurs when a new or different moral system arises in a society with established moral values, which causes panic in the moral sense.

Mass or collective hysteria represents collectively obsessive behavior due to the illusion of a real or imaginary threat, and is transmitted through rumors.

Mob is the emotional exploitation of a particular individual or group with some clear purpose or benefits.

Fad refers not to some unconventional behavior that is associated with a particular group of people in a very short time.

This statement is false!
 
It is false that political parties are mentioned in most of the articles in the US constitution, (just recall reading some articles of the constitution: if they were mentioned in most of them, you'd remember this).

In fact, they're not mentioned in the constitution at all!
