Remember, Marshall had two versions of the speech: the official and the transcription. The official version was the one he intended to give, while the transcription was, well, transcribed from the version he did give. It only differs in the opening and closing bits.

Let's check out those differences in the ending.

In the official version, Marshall closes with a call to action. This is that appeal to American Exceptionalism. He says there's a problem, anyone smart would agree, and the United States has the power, and therefore the responsibility, to do something. The Marshall Plan Speech was an argument, and this was the mic drop.

For the transcription version, he includes some closing remarks. These are a few reiterations of what he was saying, pointing out that while he didn't mean to get technical, he had to. The problem is too distant from most people, he says, so he had to lay it out. That's how important what he's talking out is.

It feels a little more informal, and sounds like a man actually engaging with his audience. This is an important skill for a public speaker to have. Know when to stick with your remarks, and know when to talk like you're having a conversation.

Written version:

An essential part of any successful action on the part of the United States is an understanding on the part of the people of America of the character of the problem and the remedies to be applied. Political passion and prejudice should have no part. With foresight, and a willingness on the part of our people to face up to the vast responsibility which history has clearly placed upon our country, the difficulties I have outlined can and will be overcome. (8.1-3)

Live version:

I am sorry that on occasion I have said something publicly in regard to our international situation; I've been forced by the necessities of the case to enter into rather technical discussions. But to my mind, it is of vast importance that our people reach some general understanding of what the complications really are, rather than react from a passion or a prejudice or an emotion of the moment. As I said more formally a moment ago, we are remote from the scene of these troubles. It is virtually impossible at this distance merely by reading, or listening, or even seeing photographs or motion pictures, to grasp at all the real significance of the situation. And yet the whole world of the future hangs on a proper judgment. It hangs, I think, to a large extent on the realization of the American people, of just what are the various dominant factors. What are the reactions of the people? What are the justifications of those reactions? What are the sufferings? What is needed? What can best be done? What must be done? Thank you very much.
