The correct answer for this question is this one: "to explain the rights of heirs and grandsons." In this excerpt from President Kennedy's 1963 Civil Rights Address, he included the examples of President Lincoln's efforts to end slavery and social and economic oppression in order to explain the rights of heirs and grandsons.
Hope this helps answer your question and have a nice day ahead.
        
             
        
        
        
Greek and Latin matter because it helps us with the pronunciation of words and the origin of words.  When we know about where these words come from, how they are broken down (with suffixes and prefixes), and how each are pronounced, you better understand not only the word, but the meaning and the logic behind the word.  This also aids in reading comprehension.  Greek and Latin is key to understanding vocabulary, and a good vocabulary helps you to understand what you are reading.
 
        
             
        
        
        
Remember, the thesis statement offers a summary of your main point.
ie.
Essay title: You will never understand a person  until you consider things from his point of view.
Essay thesis: It is important to consider things from others point of view because you can develop a different perspective of the world and comprehend the emotions of others. 
All work is mine, as it is from an essay I wrote in my freshman year.
