Final answer:
Option b) 'Many individuals were deported without due process' is the sentence that best supports the idea the Palmer Raids unfairly targeted people from other countries, as it illustrates a lack of fair legal treatment based on their nationality.
Step-by-step explanation:
The student asked which sentence from the article supports the idea that the Palmer Raids unfairly targeted people from other countries. Looking at the provided options, the best choice is b) "Many individuals were deported without due process." This option directly addresses the injustice towards immigrants, as due process is a legal right and being deported without it signifies a lack of fair treatment specifically based on their nationality. In comparison, the other options either do not specify targeting based on nationality or are less directly related to unfair treatment of immigrants.
