DoctorZIn, this article unmistakably reveals my ignorance. I can identify some, but not all, of the paragraphs' subjects.
Trying hard, I would guess (Para. 2) Pahlavi, (3) Khomeini, (4) ?Pahlavi? and ?Khomeini?, (5) Khomeini, (6) Pahlavi.
I believe you're correct. Here's how I thought of it:
#2) Shah's son, #3) Khomeini's grandson, #4 Shah's son(1st part), Khomeini's grandson (2nd part), #5) Khomeini's grandson, #6) Shah's son
How are we doing, Doctor?
