Answer:
The answer is ¨They know that new evidence may lead to new impertaians.¨
Step-by-step 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.
Alright the next answer im prove is wrong is ¨they are looking for evidence to predict the future¨ . Historians most of the time do not try to predict the future but understand the past better.
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.
