Hello. You did not enter the text to which these questions refer, which makes it impossible for them to be answered. However, I will try to help you in the best possible way.
To answer these questions you will have to read the entire text and acknowledge the argument that the author is presenting. This argument is an opinion, a positioning of the author on the subject he is presenting. In this case, to answer the first question, you must identify which sentences the author uses, in the text, to justify his argument, that is, these sentences are the evidence that the author uses to show that his argument is right.
To answer the second question, you need to reflect on whether or not you agree with the author's argument. If you agree, you must provide evidence that your agreement is correct. However, if you disagree, you must also present evidence and refute, that is, fight the author's argument.
To answer the third question, you will need to understand the decision making process that was made by the American government, before entering the Spanish-American War. These decisions must be compared with the processes presented in the text regarding these questions, until you find a similarity between a decision and a process. This similarity should allow you to make the comparison.
