The Central City Church building was recently damaged by a fire that occurred overnight. The insurance company will not pay on a claim if it is determined that a fire was started deliberately. Since nobody was in the Central City Church building at the time the fire swept through the structure, the insurance company will most certainly reimburse the church for the damage caused by the fire.

Which of the following is an assumption that is required to reach the conclusion above?

【选项】The fire was not deliberately started by someone who then left the building before the fire grew.
