Final answer:
The assertion regarding nurses, doctors, and officers using coded language to differentiate between immigrants is likely false. Instead, structured discrimination and scrutiny, such as medical examinations and name alterations, were documented practices at points of entry like Ellis Island. The term 'Code Talkers' is relevant but refers to the use of Native American languages for secure military communication during World War II, not to immigration practices.
Step-by-step explanation:
The use of coded language by nurses, doctors, and officers to differentiate between immigrants is not extensively documented in historical accounts or academic studies. The statement itself could be considered false because it implies a systematic and exclusive use of code that doesn't align with widely accepted historical facts. Instead, there was structured discrimination and scrutiny of immigrants. This included the medical examination process at points of entry like Ellis Island, where immigrants underwent tests for diseases, such as trachoma, and where their names could be altered for simplicity by the inspectors. Of relevance is the Code Talkers program during World War II, where Native American languages were used for secure military communication, proving the concept of using coded language among specific groups was a practice in different contexts.
