Where are the Dateline offices located since 2011?

• A. Moved to the 4th floor in 2011
• B. Moved to the 2nd floor in 2009
• C. Stayed on the 3rd floor
• D. Moved to the 1st floor in 2012

Answer: (A)

Interpreting a timeline and how “since” signals a change that started in a specific year and continued afterward. If the Dateline offices have been located somewhere since 2011, that means the move happened in 2011 and has remained at that location from then on. The option that states they moved to the 4th floor in 2011 fits this interpretation exactly: the change occurred in 2011 and has been in place since. The other choices describe different floors or different years, which would place the change before 2011 or after 2011, not beginning in 2011 and continuing onward.
