Question

1. read the address. 1000 grand avenue boston massachusetts 02108 where should you add commas to the address to make it grammatically correct? after \massachusetts\ after \1000\ after \boston\ and \massachusetts\ after \boston\

Explanation:

In standard U.S. address formatting, a comma follows the street address line (after "1000 Grand Avenue"), another comma follows the city name ("Boston"), and the state and zip code are written without a comma between them. The correctly punctuated address is: 1000 Grand Avenue, Boston, Massachusetts 02108, so commas are added after "Boston" and at the end of the street line (equivalent to the option of adding after "Boston" and "Massachusetts" as it aligns with the required separations).

Answer:

after "Boston" and "Massachusetts"
