Pacifist commented :Only four of them dpecited Liancourt rocks, 大日本沿海略図, �鮮�海岸図,日本本州�州�四国附�鮮, �鮮全岸 - all these four maps were not Korean maps, these are maps of Sea of Japan or its surrounding lands. So I suppose the Meiji government didn't think that Liancourt rocks to be Korean territory at all. Whis is it so?

I'd be happy to help you! Let's go through each sentence and correct them:

1) In the 19th century, the majority of black slaves were born in America, although they were originally deported from West Africa.
- "In the" should be added before "19th century."
- "Greater part" can be changed to "majority."
- "Was" should be changed to "were" to match the subject "black slaves."

2) They worked for white people as servants, housekeepers, or as slaves on extensive plantations.
- No corrections needed.

3) Working conditions were very harsh because every mistake or struggle for independence was punished through cruel tortures, and even death.
- "Struggle" should be changed to "struggles" to match the plural subject "mistake."
- "Death" should be preceded by "and" to indicate that it is a part of the punishment.

4) Slaves couldn't practice their original religion and had to follow a modified form of Christianity, which defined them as servants and didn't speak of independence.
- "Christianism" should be changed to "Christianity" for the correct term.
- "Hat" should be changed to "had" to match the correct verb form.

5) However, black people were able to preserve their culture thanks to the songs that were sung on plantations.
- "Conserve" should be changed to "preserve" for the correct term.
- The word "which" should be changed to "that" to introduce a restrictive relative clause.

6) Slavery was finally abolished in 1865 when the Northern States, guided by the Republican Party and President Abraham Lincoln, won the civil war against the Southern States.
- "Slaves" should be changed to "slavery" to make the sentence grammatically correct.
- "Guid" should be changed to "guided" for the correct past tense of the verb "guide."

7) In 1984, Orwell represents a totalitarian society in which every form of individuality and independence is forbidden, and the party has conformed people and their thoughts to its ideologies.
- "Represented" should be changed to "represents" in order to match the present tense of the verb.
- No other corrections needed.
