Question

why were southern states opposed to california entering the union as a free state?
a. adding california as a free state would mean that there would be more free states than slave states.
b. other western territories would copy california and become free states.
c. representatives from california would outnumber representatives from the southern states.
d. representatives from california had expressed support for slavery in other territories.

Explanation:

The balance between free and slave states was crucial. Southern states relied on slavery for their economy. If California entered as a free state, it would tip the balance in Congress against them (more free - state representatives). This was a major concern as it could lead to policies unfavorable to slavery.

Answer:

A. Adding California as a free state would mean that there would be more free states than slave states.
