To answer your question accurately, I would need specific information about the content of the speeches given by each character in the second part of the play "I Am American." However, without having that content available, I cannot determine which two speeches emphasize the theme of immigrants coming to America to escape difficult situations.
If you have details about the speeches made by Shana Bloomstein, Jane Bradford, Max Littlefoot, Ty Smith, and Juanita Ramirez, please share those, and I can help analyze which ones highlight that theme. Alternatively, if "I Am American" has been discussed in a particular way in your studies or class notes, those insights could also lead to a better answer.
