Yeah but just make sure to give reasons why in the sentence after that
If the passage is about the human errors that contributed to the spread of the fire, only details that prevented the firemen from being able to contain the fire should be used. The sentence "Even after the fire, Brown was confident..." shows that Brown was confident in his decision. This sentence does not however directly contribute to the firefighters inability to effectively contain the fire at the time of the fire. This takes place after the fire has done the damage.
Its A. because -ed is past tense.
