The main pattern of organization in the selection of this text is b. cause-effect. It is quite obvious that that is the correct option because the text simply blares it out loud. What I mean by that is that the text is not complicated--it gets right to the point. Transition words like first of all and another result are generally used when writing a cause and effect paper. To prove my answer option true, I provide you evidence from the text: sentence (1) is the opening statement and identifies the cause. Sentences (3) and (4) are followed as effects to the cause.
