Answer:
Two or more dependable sources that record the same event using the same facts is needed to establish historical accuracy.
Step-by-step explanation:
Artifacts can be open to interpretation because historians need to figure out what they are & what they mean about life in the time they were made.
Although primary sources are helpful, they are not indisputable because one person cannot completely confirm an event. Consider what would happen if future historians only used a conspiracy theorist's journal to figure out what life in our current time is like.
Religious documents often record fictional events.
Two or more dependable sources is the right answer because more resources mean that something is more likely to be true.
