Which source would best a historian understand the cause and effect of the great chicago fire on families?

The answer is letter C.) a newspaper editorial about families who were displaced.

A newspaper editorial refers to the opinion of a leading staff or writer of a newspaper. This would share data on how families were affected by the Great Chicago Fire, through the lens of an educated staff. The other sources presented only speak a small percentage of the families/people affected by the fire.
