Question

an effect of the supreme court’s ruling in scott v. sandford was that
legal protection for slavery was strengthened.
legal protection for slavery was weakened.
the abolitionist movement was strengthened.
the missouri compromise was strengthened.

Explanation:

The Scott v. Sandford (Dred Scott) ruling stated that enslaved people were not citizens and that Congress couldn’t prohibit slavery in territories. This strengthened legal protection for slavery. The other options are incorrect: the ruling weakened the abolitionist movement (not strengthened it) and declared the Missouri Compromise unconstitutional (so it wasn’t strengthened), and it strengthened, not weakened, slavery’s legal protection.

Answer:

A. legal protection for slavery was strengthened.
