Can you please check these sentences I'm not sure of?

Thank you very much.

1) A white man asked Rosa Parks to give up her seat to him/to get up because he wanted her seat/to stand up-
Which ones are best?
2) The boycot would have been a success, if Rosa Parks hadn't refused to give up her seat to a white man.
3) The Civil Rights Movement was a non-violent organization, which fought for civil rights and equality for black people.
4) Martin Luther King campaigned against segregation laws.
In the famous speech he gave (held/made)
5) He believed that people should be discriminated against on the basis of the color of their skin. He wished there would be a day in which people wouldn't be judged by the color of ther skin but by the content of their character.
6) Five years later Martin Luther King was dead (is the same as "died"?)
The Civil Rights Act was passed in 1964, which protected black people discrimination and in 1969 schools were desegregated.
7) I use the net to do (carry out) school research, look up information I need for school and keep up to date on what happens in the world.

Choose the five ....

1) In the first sentence, there are a few options that can be considered correct, depending on the intended meaning:

- A white man asked Rosa Parks to give up her seat to him.
- A white man asked Rosa Parks to get up because he wanted her seat.
- A white man asked Rosa Parks to stand up.

2) The sentence is grammatically correct, but the word "would" should be "could" to indicate a hypothetical situation: "The boycott could have been a success if Rosa Parks hadn't refused to give up her seat to a white man."

3) The sentence is mostly correct, but it should be "...which fought for civil rights and equality for black people" instead of "organization" to clarify that the Civil Rights Movement was an organization.

4) The sentence is correct, but the word "held" is more appropriate than "made" in the context of delivering a speech. So it should be: "In the famous speech he held..."

5) The sentence has a minor error. It should say: "He believed that people should not be discriminated against on the basis of the color of their skin." Additionally, the word "people" is repeated, so it could be rephrased as: "He believed that there would be a day when individuals wouldn't be judged by the color of their skin but by the content of their character."

6) Yes, "Martin Luther King was dead" is the same as "Martin Luther King died."

7) The sentence is correct, but I would suggest a small change. Instead of "carry out," you can use the word "conduct" to make it sound more formal: "I use the net to conduct school research, look up information I need for school, and keep up to date on what happens in the world."

Overall, your sentences are well-constructed and convey their intended meaning effectively. Great job!
