The Emancipation Proclamation issued by President Lincoln A (triggered the start of the Civil War)
B (was supported by both Northern and Southern states.)
C (freed all enslaved people under Confederate control.)
D (was prompted by the Dred Scott decision.)

C

Explanation:

A is not correct because the Emancipation Proclamation was issued after the beginning of the Civil War in the year 1863. B is incorrect because the Emancipation Proclamation was not supported by those in the South. D would not be correct because the Dred Scott decsion was not a factor in issuing the Emancipation Proclamation. Also, that court case happened in 1857, which was 4 years before the Civil War began. C would be correct because it stated that slaves living in Confederate states would be technically free.

the catholic church withhold people's access to the bible during the middle ages.

people could go to church and listen to the teachings, but it was absolutely forbidden to own and/or read the books of both the old and new testaments. it was also prohibited to translate the books (which where originally in biblical hebrew) to any other language.

this was done so the church could remain in control of what their teachings were and to enhance their importance and power, while also being able to judge people's actions through information that was unavailable for the general public.
