Yet 24 about grinding poverty, hunger, and dreadful need proceed more from the United States than from countries with one-fortieth of their living standard.

The amount of potential human discontent has always been 38 — misery, failure, misfitting, bitterness, hatred, envy 39 telling. It has usually failed of 40 , and in the past it was accepted passively as being beyond help.

Passage 1
In the United States, it is not customary to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 p.m. If someone receives a call during sleeping hours, he assumes its a matter of life or death. The time chosen for the call communicates its importance.
In social life, time plays a very important part. In the U.S.A., guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts of the world. Thus, misunderstandings arise between people from cultures that treat time differently.

A. its a matter of work
