Hello. You did not inform the article to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
To answer this question, you will need to read the entire text and identify the part of the text where the topic you will need to analyze is exposed to. The authors will approach this topic through evidence, that is, through statements that justify their point of view and their position in relation to the topic. In that case, you must analyze what the evidence is similar and what is different, between these two authors, in order to be able to compare and contrast the way they approach the topic. These evidences can be presented explicitly, where the authors present them directly, or implicitly, where the authors present them indirectly and subjectively.
