Which democratic concept reflects judeo-christian influence?
a. people should elect their leaders.
b. responsible citizens vote in elections.
c. a person is innocent until proven guilty.
d. people are entitled to freedom of speech.

c. A person is innocent until proven guilty.

Explanation:

The Jews had "innocent until proven guilty" as a principle, since the law of Moses required them to have a justice system based on proofs.

The Witnesses stood next to someone accused, requiring to submit evidence, as stated in Deuteronomy.

A single witness was not enough, and judges were to carry a careful investigation to solve the case.

Deuteronomy 19:15 states:

You cannot convict anyone of a crime or sin on the word of one witness. You need two or three witnesses to make a case. If a hostile witness stands to accuse someone of a wrong, then both parties involved in the quarrel must stand in the Presence of God before the priests and judges who are in the office at that time. The judges must conduct a careful investigation

In case someone falsely blamed another one, punishment followed:

if the witness turns out to be a false witness and has lied against his fellow Israelite, give him the same medicine he intended for the other party. Clean the polluting evil from your company.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
