So-called environmentalists have argued that the proposed Golden Lake Development would interfere with bird-migration...

In the stimulus, it says that "virtually every" development proposal brought before the council in recent years indicates that their expressed concern for the environment... but then the answer says: "Not every" development proposal opposed in recent years by these so-called environmentalists was opposed because they believed it to pose a threat to the environment. I don't understand what these two statements are saying and why A isn't just repeating what the stimulus says.
