in nassau county, new york
near newark, new jersey
near pittsburgh, pennsylvania

The correct answer is B. In  Nassau County, New York

Explanation:

The word "Levittown" refers to different massive suburbs that were created after the World War in the U.S. and Puerto Rico and that were called "Levittown" because these suburban developments were created by the company Levitt & Sons. The objective of these suburban areas was to prove an alternative to cities especially to those that return from the war and their families. The first Levittown was built in New York in Nassau County, Long Island between 1947 and 1947 and this was followed by a Levittown in Pennsylvania (1952), New Jersey (1958) and later Puerto Rico (1963). Therefore, it can be concluded the first Levittown was built in Nassau County, New York.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
