Hello Everyone,

I have come across the below question and thought that this is an example of the verb coming before the subject. Could you please clarify this. Should it be plural or singular

The time when the apartment building in downtown Milwaukee started on fire has been determined by the fire department,but what is problematic to establish are/is the source of flame,the mechanism by which it ignited the building,and the extent of the damage.
If you have any questions
