why do historians continue to gather historical evidence for even well-known events they want to find artifacts to sell...they are looking for evidence to predict the future... They know that new evidence may lead to new impertaians... They assume that new technology will prove all of the old series incorrect...

pretty sure its "They know that new evidence may lead to new impertaians"

The answer is ¨They know that new evidence may lead to new impertaians.¨

Explanation:

Okay to prove to you this is the right answer I am going to tell you why the other answers are wrong. Lets start with ¨to sell the artifacts¨  okay the reason this is wrong is due to the fact historians do not sell artifacts they put them in museums.

Now lets prove the last answer wrong ¨They assume that new technology will prove all of the old series incorrect¨  Okay so historians do not get item from the past to just say how dumb their design is or how unefficient they are.

answer; i believe that the correct answer to the above question is; (tariff)
