Answer:
D. Children are in danger because of the road conditions on Green Street.
Explanation:
An inference is a conclusion made based on pieces of evidence and reasoning. When we're reading a text, we can make various inferences based on the details we're offered. Not all information is presented explicitly, which is why this process is very important. That is the only way we will fully understand the text.
Based on the text you were given, we can conclude that children are in danger because of the road conditions on Green Street. We're told about how close to children cars and trucks are and how lucky we are that the number of accidents is relatively low. These are the details that lead us to this conclusion. This is why option D is the correct one.
The rest of the options aren't supported by details offered in the text, which is why they are incorrect.   
 
        
             
        
        
        
I feel like he's saying, when slaves came to America, they weren't welcome to all the holidays, they were whipped instead of celebrated (on this day particularly), and then the day finally comes when they get to celebrate the Fourth of July but they can't really celebrate it because too much bad stuff happened that day. He's been saying why should anyone celebrate it when they know slavery was going on at that time. Now Douglass was an African American and this is his perspective. If you ask a Caucasian what they did that day, they will have a different story. That's what Douglass means when he says, "The story of most nations is difficult to catalogue."  I hope this helps! :)
