Answer:
A) It provides an interesting firsthand experience of an immigrant whose sister was “indeed momentarily rejected” because she had been sick and had bloodshot eyes.
Step-by-step explanation:
"some immigrants were detained at Ellis Island for more examinations." This sentence gives you the advantage to get more information about what the answer will be. Use "who" "what" "where" "when" in your process of elimination. What happened? Who was there? Where did this happen? When did this happen?
Hope this helps!!!
