Use the passage below to answer all parts of the question that follows.
"But recently, in an interview with the French governor-general, we happened to discuss the situation in our province. Here are his views. He knows quite well that you are committed to your righteous cause and that you are also utterly selfless. But though you have no thoughts for your own person nor for your own family, you should at least attend to the sufferings of the population of a whole region. The governor mentioned this to me because he knew that I was from the same province as you and that we might together devise a plan to save it. His words are not worthless, and this is precisely the reason why I can no longer remain silent.
Are you not ashamed to see that the governor-general, who comes from a foreign country several thousand miles away, knows how to care for our people while we, who were born and raised in this country, remain blind to the sufferings of its people? How will they judge us, the generations a hundred years hence? I have always been taught that superior men should consider the care of the people as fundamental; who has ever heard of men who were loyal to their king but forgot the people's aspirations?"
