The correct answer is:

A. Travel helps people understand the world around them.

In these words, Mark Twain expresses how important it is for men to travel, because traveling is acquiring a piece of knowledge, a piece of culture, customs, that are different in every part of the world. Enriches men and gives him a broad point of view about life.  

Mark Twain wants to emphasize that “Travel helps people understand the world around them.” since it opens our mind to new worlds, new people and their ways of living.

Option 2 is incorrect since traveling in itself is learning experience no matter if you are educated or not.  

Option 3 is incorrect as Twain means exactly the opposite, that travel opens your mind, it doesn't close it.

Option 4 is also incorrect since Twain does not refer to the costs of traveling and he does say that it is useful to most people.
