6. Approximately what percentage of the "bachelors" — the men who populated America's Chinatowns until the 1960s — were actually married?

Incorrect! You answered (c) 20%.

The correct answer is (d) 50% of these men were actually married, but the Exclusion Act prevented them from bringing their wives over from China. As Bill Moyers says in the series, these years tell a story, "of a people in between countries, often unsure to which they belonged. It's about families kept apart — lives shaped and mis-shaped by Chinese custom as well as U.S. law."
