The correct answer is: I have tentatively chosen an excerpt from the presidents inaugural address that i'd like to use in my report. Unfortunately, the passage is far too long to reproduce verbatim.
We use the word tentatively to show that the individual has attempt to choose the excerpt to use in his/her report. And lastly we use the word verbatim to explain that because the passage is too long, it is not possible to reproduce it line by line in for the report's means.
