An archeologist discovers an official-looking seal during an archeological dig. the seal is cylindrical in shape and is much like what a king would use when signing letters. not long after, the archeologist finds a clay tablet covered in cuneiform script. the archeologist translates the words on the tablet. he discovers that it states a set of laws and rules that the citizens of the civilization must have had to follow.

The civilization had a functioning government in place that decided the law of the land.

Explanation: This is the only logical conclusion that we can get from the information providen by the passage. Let's begin, the passage shows us that there was probably a king in that civilization as the official looking seal is similar to others. The archeologist can compare his knowledge from other ancient civilizations and supose that this one has that thing in common. The tablet with cuneiform script demonstrates that the civilization was organized enough to have laws and rules, there were some problems that were so common the government needed a way to treat them.  

So the government was stable enough to apply rules over the citizens, making it functional.

The things we can't know from the information is who wrote in the tablet, it could be the king or someone designated for that job. The content of the tablet doesn't say if there was one king or various governors. Lastly, the things found out by the archeologist only give us information of that specific civilization, we can generalize.
