Can some expert please explain why the answer is D and not B?
I initially chose B as well not now that I think of it, perhaps the answer is not B because it's too specific. If the answer choice said something like experience of people is important in good functioning of the government, that would probably make sense. But it states as "the most important" which is far-fetched and not what the argument depends on.
You are right about B.
Well, two aspects of B that formulate it i.e. "important factor" and "experience" are presented with as if they are central core of the passage which is not true.
"most" creates an impression that govt. focuses most on "experience" which logically if you push into the passage it does nothing to help it. Instead it feels misdirected. Even if "most" was not there, this choice would not have made sense.
HTHs.
