Answer :
Long and short term memory are said to be separate because brain damage can leave one but not the other memory intact.
How do we know that long-term and short-term memory are different?
When a person gets brain damage, it is entirely possible that they will no longer be able to remember things in the short-term, but remember them in the long-term. Or vice versa.
This shows that these memories are different because one can be affected independently of the other which wouldn't be the case if they were the same.
