How did marquette and jolliet strengthen french claims to the area around the mississippi river?

The way Marquette and jolliet strengthen French claims to the area around the Mississippi river:

Jacques Marquette and Luois Joliet set out to explore the whole area of Mississippi river in 4 months under the order of Frontenac for King Louis XIV who was an absolute Monarch. Jolliet thought that the whole north-west way of the river led to the Pacific Ocean.

Later they learnt from Indians that English or Spanish settlers were living along the south of the river.

After exploring, their expedition opened Mississippi to the trade and settlement for New France. Jacques Marquette was the very first European to discover the northern part of the river.

for the 2 countries u can do china and america because america has a democratic government while china has a communist government.

a democracy is a government run by the people either by directly voting or indirectly by electing representatives. an oligarchy is a government run by a few or a small group of people. a democracy and oligarchy are similar because both in an oligarchy and an indirect democracy, a small group of induvial determine the laws for a large group of people they are different because in an oligarchy it is easier to control and they do not have to answer to a large number of people in the country, unlike a democracy where they do have to answer to a large number of people an county that is a democracy would be the united states. a country that is an oligarchy would be the china.
