[spoiler]The phrase 'as old as' is used when two objects are equivalent of age; here, we are trying to say that one object is 2000 years older than the other. Hence, the answer is probably B.[/spoiler]

Have you wondered how you could have found such a treasure? -T

According to me - the sentence says, ... nearly 2000 years ...
Hence it might be better to use "Older than" instead of "as old as".
Also "Mediterranean" qualifies "predecessors" - we need a adverb "supposedly" instead of "supposed".
