Explanation: This statement is true because, people who are dependent on each other are more likely to be tolerant of each other because they still need each other. While the reverse is the case for two persons independent on each other. For instance, in an independent relationship or conversation between person A and person B, knowing fully well that they both have no need of each other, it would be easier for them to have a disagreement because they have nothing to lose if they part in different ways.
On the other hand, person C and D who are dependent on each other would be more tolerant of each other in an argument.
It is true that putting thoughts into words requires a knowledge of a language's structure and vocabulary. Not so much of its structure, but you definitely need to know a few words if you want to get your thoughts across.
