40 days are important because:-
Grade wise:- If you were to miss out on 40 days of classes, it would bring you very behind in your classes. Your grades would drop tremendously and you would get stressed.
Health wise:- If you dont brush your teeth for 40 days, or even go off your diet for 40 days, your health would be in danger. YOU NEED TO BRUSH YOUR TEETH AT LEAST TWICE EACH DAY!! Also, make sure you keep a balanced diet. :)
The answer would be letter D. <em>The hideous and revolting conduct of the past and present</em>

B, although maybe the main argument to sustain the author's point, it's still not the main idea he aims to pass.
The author intent is to show what the Fourth of July looks like from the slaves' point-of-view. For that, he reminds people of the disparity between them (free white people) and slaves, of how the feelings of liberty and justice do not encompass all. And because of it, this day may be a celebration occasion to them, but to slaves, it's a 'mourning' occasion, with nothing to rejoice or be proud of. Finally, he concludes by stating "<em>Whether we turn to the declarations of the past, or to the professions of the present, the conduct of the nation seems equally hideous and revolting.</em>" - which is the answer to the question.
