This is a hard SA question, and I don't see what I am missing. How is answer choice A a sufficient assumption?
My diagram:
(Solution to environmental problem not caused by the government)--->(Major change in consumer habits)--->(Economically Enticing)
Therefore, (Not Economically enticing)--->(Few serious ecological problems solved).
What I am looking for: This is a pretty simply A to B to C argument, and the conclusion as a Not C in it. To link up the chain, say (Not solution to environmental problem not caused by the government)--->(Few serious ecological problems solved).
Answers B-E are way wrong, but I don't see how answer A paraphrases the sufficient assumption at all.

Contraposed (using De Morgan’s Law); "If there’s no major changes, then either there’s no solution to the problem or it’s caused by government mismanagement.”
I’ll be the first to admit it. I totally reverse engineered that one. But I can’t think of any other way to make A a sufficient assumption.
I think A includes that idea. I'm not sure how you're trying to link up the chain.
This is an SA question:
Premise: A solution that is not the result of government mismanagement requires major changes in consumer habits, Major changes in consumer habits require changes that are economically enticing (/GM→MC→EE)
Conclusion: If solutions aren’t made economically enticing, then few serious ecological problems will be solved. (/EE→FES)
Analysis: The structure is
A→B→C
———————
/C→D
We need to fill the gap. The sufficient condition of the conclusion triggers the the premise chain by denying the its necessary condition. The gap could be filled by either /B→D or /A→D. The D represents the new concept mentioned in the conclusion (few ecological problems), and we’ll need to make that a necessary condition to either the negation of B [no major changes (/MC)] or the negation of A [the result of government mismanagement (GM)]
Answer A fits the bill. All of the other answers are out of the scope of the argument’s gap.
Answer A bridges that gap. If only few problems are a result of government management, then the two worlds overlap almost perfectly. Only a few problems from the whole world will be outside of the world discussed by the argument. Since the conclusion doesn't say "No problems will be solved, but "few" problems will be solved" an almost perfect overlap is good enough to guarantee the conclusion.
