I found this question online. It is about "Blaxicans" by Richard Rodriguez.
Answer:
The second sentence in line 3 really means that immigrants are changing America.
Explanation:
"Blaxicans" is an essay by Richard Rodriguez concerning how immigrants are assimilated by America and its culture, and how they can both influence and be influenced by it. In the first paragraph, line 3, the sentence "Immigrants seem to be bent on undoing America" does not truly mean what it says. Rodriguez relies on verbal irony, and this is one example of it. As we know, "to undo" means to reverse or overturn something. But this is not Rodriguez's point at all. Immigrants are not overturning America. Instead, they are changing and strengthening it.
