The primary purpose of the passage is to:
fight is between
(c)describe the evolution and application of a certain financial device &
(d)explain the popularity of leveraged buyouts during a certain period
MGMAT test review says C. I disagree.
D is more convincing b'cos the passage is about certain specific period "early to mid 80s" and in last para they say "The 1980s were the heyday of the leveraged buyout" I would call that popular.
whereas for C, wouldn't evolution pertain to what it was and what it it is now...evolution is about change; in this case it should have been change in the that financial device. Do we see any such change mentioned in the passage? Anything saying how it was practiced in past and how it is practiced now?
Please help.
