Which issue inspire the constitutional convention?

a. states were demanding more rights from the central government.
b. the war against great britain was going poorly.
c. the government under the articles of confederation was too weak.
d. conflicts over slavery between the states were becoming heated.

The answer to the question above is option C. It is actually the issue of Articles of Confederation that helped inspire the Constitutional Convention. The central purpose that urged the Constitutional Convention was the revision of the Articles of Confederation knowing that the government under this was too weak and incapable. When we say Articles of Confederation, this includes the established functions of the government, particularly the United States of America after its independence declaration.
