With which place was Einstein associated in America?

Correct answer: Princeton

The correct answer is Princeton. After settling in the United States, Einstein became associated with the Institute for Advanced Study at Princeton, New Jersey, where he continued his intellectual and scientific work. The question uses a place-name clue from the later part of his biography rather than asking for a general American city. New York Theatre, Los Angeles Stadium, and Boston Harbour are invented or unrelated locations and have no meaningful connection with this biographical detail. Therefore option B is unambiguous. Remembering Princeton helps connect Einstein’s American years with the institution where he spent the later part of his career.
