Hello. You did not submit the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
The only way to answer this question is to read the text it refers to. During this reading, you will be able to identify if the authors disagree, if they present opposite opinions on the same subject. Once you've identified this, you will need to understand what point in this issue they disagree with and why this disagreement is happening. This reason will be exposed in the textual evidence, where the authors will present sentences that justify their opinions, showing why this opinion is correct.
What these authors discover about the research will be presented in the conclusion of the text, in the last paragraph, where the authors can infer about everything that was discussed in the text.
