Here, why is option d incorrect?
Provisions were made against the advantages, but they were still skeptical about the proposal. The contradiction makes sense
Imagine you’re playing a game, and there are some rules (or “provisions”) to make sure everyone has a fair chance. But instead of these rules being against the problems or unfair parts of the game (which would make sense), they’re against the fun parts (the “advantages”). That would be pretty strange, right? Why would anyone make rules against the good parts of the game?
So, while “provisions” isn’t wrong by itself, pairing it with “advantages” creates a confusing message in this context.
