Answer:
Ancient Egyptian writing became more complex over time.
Step-by-step explanation:
The given excerpt tells us that ancient Egyptian writing became more complex over time. Writing in Egypt began about 3100 B.C. and it consisted only of hieroglyphs of names or titles that accompanied images of important people. However, by 2500 B.C. ancient Egyptian writing became more complex - complete sentences began appearing on tombs, as well as lists of offerings to the Egyptian gods. We can conclude that, from then, their writing became even more complex.
The text doesn't claim that ancient Egyptian writing was found only on tombs, that only wealthy people had tomb inscriptions, or that most of the Egyptian writing was about Egyptian gods. These things are mentioned, but that doesn't mean that they were the only things that existed. This is why the first option is the correct one.
