Hello. You have not submitted the texts to which this question refers, which makes it impossible for them to be compared. However, I will try to help you in the best possible way.
Your question shows that the two texts are different and present similar ideas. This presentation of ideas is made based on the evidence and supporting details that the texts present. Both the evidence and the supporting details are placed in a text to prove and justify the ideas and arguments presented, showing that these ideas and arguments are real and true. In this way, you can show the similarities that these texts have through the evidence and details of support that they have in common and are related to the ideas and arguments they promote. To present the differences between the texts, you must show the evidence and supporting details that are different between the two texts, but that are also related to the same ideas and arguments.
