Explanation:
The U.S. Supreme Court is the highest court in the nation. Its decisions set precedents that all other courts then follow, and no lower court can ever supersede a Supreme Court decision. In fact, not even Congress or the president can change, reject or ignore a Supreme Court decision.

City-states would be independent, but their power would extend very little outside of the city-states borders.
Its TRUE that the effect of the crusades can still be seen today.
