Read the excerpt below and answer the question. authentic record containing it. Which word is closest in meaning to the word "authentic"? old-fashioned reliable initiative unaltered

I would say unaltered, since authentic means not false, real. I don't know the context behind this sentence to understand it better, but I can figure out it makes reference to the original, the real record.

The other words do not apply: old-fashioned is related to a past era, reliable does no necessarily imply real and initiative has to do with something that is introductory or preliminary.

Reliable
