Why are historians able to rely on well-known museums for accurate information about the past?

Because

Explanation:

In museums there is usually information about certain object. And about other information?

Usually there is a group of people who check the information, compare it to other similar ones and then "publish" it (hope I used the correct word)

That's the reason why information in museums is usually quite correct

Though hope someone else answers your question too

Like the question you asked about, it's always better to have other sources of information to compare with

i believe george gallup used a poll in 1936

to find facts and details to use as evidence! : ) hope this .
