Answer 2

The sentence you provided appears to be incomplete, and it's unclear what you want to express. However, I can help you complete it based on my understanding. It seems like you want to express that eight volumes of an epic or epos were supposed to be published by 1984. Here's the completed sentence:

"Since 1984, eight volumes of the epos were supposed to have been published."

This sentence indicates that by 1984, the expectation was that eight volumes of the epos should have been published, but it doesn't specify whether they were actually published or not.
