    Hi An,

    I like your critical thinking here.  I don't have access to the drawing associated with this question.  Could you please post it?  If the storage is S-1 and the gallery is A, you are correct that it'd need to be 2 hr not sprinkled, or 1 hr sprinklered.

    But I'd bet a sprinkler head is shown on the plans (?) or sprinklers are mentioned somewhere in the scenario.

    The answer uses this chart from IBC Ch 5: 

    Hope this helps!

    Yes, in the basement there is a room called out as " Mechanical Sprinkler" I assume it indicates that the whole building is sprinklered.
