We can say that Obama does not use an objective tone in the excerpt because he gives his personal opinions on democracy, as stated in option A.
What is an objective tone?
We say a speaker uses an objective tone when he does not convey his personal opinions or biases. A speech is objective only when it conveys facts, without any sort of personal views included.
That is why the excerpt from President Obama's speech that we are analyzing here cannot be considered objective. All of what is said can be disagreed with. Many people may have a different opinion and counter-argue by saying that American democracy is never taken for granted, or that its democratic institutions do not need any rebuilding.
For that reason, we can select option A as the correct answer.
- No, because he gives his personal opinions on democracy.
