The answer is George Washington. Hope this helps :)
It would be that "c. the chairman of the veterans' bureau laundered nearly 200$ million" that was not a scandal associated with the harding administration, since this in fact happened during the previous term.
the last sentence is the one I think
What I can understand from your question, rational use suggest that you use things in a rational way or in a logical,astute,prudent way. This means, for example, you are lost in an island and you know someone is going to look for you in the following 10 days, still you dont know in which day you are going to be rescued. Because you are an inteligent human being you will decide to use your things in a rational way as if you dont do it you will have a shortage of supplies and most probably you are going to die.
-Hope this works...
