in the 1890s, southern states enacted a new form of black codes, called “jim crow” laws. these laws made it illegal for blacks and whites to share public facilities. this meant that blacks and whites had to use separate schools, hospitals, libraries, restaurants, hotels, bathrooms, and drinking fountains.

explanation:

to eliminate ambiguous remote or broad reference it is necessary to focus on anaphoric reference. by definition "anaphoric reference means that a word in a text refers back to other ideas in the text for its meaning." the references should be clear and leave no room for ambiguity.

in the first case the pronoun it probably refers to the car but it has not been mentioned before so we should replace it for the car. in doing so the statement becomes clear.

in sentence number   two   the pronoun he refers to charles dickens the author. yet, the first half of the sentence is about the book a tale of two cities. to repair this it would be better to rephrase the first half : after i read   a tale of two cities by dickens, he so as to remove the remote reference.
