To identify which two speeches emphasize the theme of immigrants coming to America to escape difficult situations, you would need to reference the content of each character's speech. Based on the information given in the question, I can’t provide a specific answer without that context.
However, typically, speeches that express struggles, hopes for a better future, or the challenges faced in leaving one's homeland would align closely with the theme of immigration for better opportunities. If you can provide more context or content from the speeches, I could help determine which ones align with this theme.
