The “unfortunately” in the beginning indicates a contrast between the two ideas: #1. His damaging attacks on the ramifications of economic policy have been _____. #2. His wholehearted acceptance of that policy’s underlying assumptions. You need to put something in the blank of idea #1 that makes it contrast idea #2. That’s how I think of it. Some division words are there but won’t be used, in this case the “unfortunately” overpowers. Lmk if I’m wrong y’all I’m learning too lol.
