How many years after its establishment did the San Francisco Fire Department celebrate its 150th anniversary?

• A. 125 years
• B. 150 years
• C. 100 years
• D. 75 years

Answer: (A)

The San Francisco Fire Department was established in 1866. To determine when the 150th anniversary was celebrated, you would add 150 years to that year, resulting in the year 2016. To find out how many years after its establishment that was, you subtract the establishment year from the anniversary year: 2016 - 1866 = 150 years. However, the question asks how many years after its establishment the Department celebrated its 150th anniversary. This is where the calculation can seem misleading in the context of the options. To clarify, one must think of how many years passed from the establishment to the point of celebrating the 150th anniversary. In fact, 2016 minus the establishment year of 1866 gives a sum of 150 years, which is not the choice presented but rather means that 150 years is when the celebration occurs. Thus, the two options that would indicate a timing interval in the choices don’t directly answer the question as intended, with A suggesting a misinterpretation in calculating the elapsed time. The correct approach is to consider that the anniversary was celebrated 150 years after the establishment, so the direct question becomes about understanding the timeline rather than simply counting back from the event
