How is this excerpt of an expository essay organized? excerpt: conversational ballgames this is connections academy language arts lesson 18 unit 3

I searched the excerpt which name is conversational ballgames and after I read it I got to the conclusion that it is organized the following way:

1.First, the author COMPARES the western-style conversation with the tennis game and she says that they are similar because in the western style when the person who is talking introduce a topic then she/he is expecting the other person to agree or disagree and keep talking about the reasons why, she says that she only doesn’t wait for you to agree or disagree, she expected more than that. Just like in the tennis game, if you throw the ball you expect from the other person to hit it back.

2.And then, when the author talks about Japanese-style conversation, she says that it isn’t like tennis or volleyball at all; there, she CONTRASTS the Japanese-style conversation with the two other games saying how different the games are from the Japanese-style.  

there is a sequence and logical steps to give an answer of a trouble.

1) strategy is necessary to develop an project idea.

2) to study and know the environment where you are going to work ( ecosystem).

3)   the materials resources to built the ideas.

4) to give a priority order in the context that you study. in this case human needs.
