Answer:
Individuality
Explanation:
Individuality is the attributes of a certain person or thing that separates them from others of the same class, mostly when strongly marked.
To explain this, let's consider a usual idiomatic statement in English:
"He/she marches to the beat of a different drummer."
We use the idiomatic statement to describe someone who happens to be unique from the crowd, thou a bit odd or eccentric, or who acts in an unpredictable and different ways.
Lets rephrase it this way, "in situations where people march along to the beat of a drummer, an individual could be hearing a separate drum-beat, because he or she is marching in a total different rhythm.
The sentence is a variation of that expression speaking of individuality.
