Answer:
The first part of this sentence is a fact, the second part is an opinion.
Explanation:
The reason why the second part is an opinion is because workers built the tombs, not the pharaohs. It is correct where it says the tomb were built for the pharaohs, but it wasn't by themselves; in fact, they didn't even do any of the work on the tombs, they just saw the progress of it.
The opinion is “to make sure they would have eternal life.” And the fact is “pharaohs built fabulous tombs for themselves.”
