Typical North Americans carry around with them an air space of about two feet in any
direction. They feel uncomfortable when they
are bumped or when this air space is
penetrated in any way. When they are required
to make some sort of physical contact with
other North Americans they do so by
extending their hand rather tentatively out
through their air space to join another hand
that has reached out through another air
space in what is known as a handshake. The
hands are then immediately withdrawn and
there is rarely another physical contact

The correct answer is C. Typical North Americans do not like to interact with each other at all.
