You forgot to add the passage for this.
I'd say B and D. Elementary school reports don't necessarily equate to knowledge of a subject (and research on the branches of government doesn't help you know <em>how</em> to govern), so A is out. C is nice, but popularity and charm do not a leader make, he might have ulterior motives to being as such, maybe taking advantage of the power? B and D show things he has done that would give him useful skills in the position.
The only word I'm seeing that could be an adjective is the word "old".
(Correct me if I'm wrong, thanks!)
Have a great day!
The answer is:
"Last week I sent a tuner over to my parents’ apartment and had the piano reconditioned, for purely sentimental reasons.”
This is intrisic because she says, "purely for sentimental reasons" meaning she wasn't influenced by anything from the outside, this was something she did on her own based on how she personally felt. It was based on her emotions and her feelings. Hope this helps:)
