What does this passage imply about the importance of
laws within individual states?
for laws to be just they must be common to all
humankind
laws reflect the customs of each state and
common laws of mankind.
all laws should be made available to other nations
so that they can make use of them.
natural reason is the only source of all laws for all
people

b. Laws reflect the customs of each state and common laws of mankind.

Explanation:

In a federal type of government, each state has the right to draft its own laws.  This is important because it allows each state to make decisions based on its particular situation.  Since not all states are the same in terms of population, economic activities, size, etc., it is important for each state to be able to make laws that are in its best interest.  These laws will therefore reflect the customs of each state, but will always be based on the common laws of mankind.
