Can anyone help me with the structure: mistake(confuse) sufficient/necessary for necessary/sufficient? Any explicit example would be be appreciated
Hi Hayley:
Here is an example of confusing necessary for sufficient:
The grass needs water to be green. Therefore, anytime there is water, the grass will be green.
(sufficient) grass is green --> (necessary) grass gets water
Therefore,
(sufficient) grass gets water-->(necessary) grass is green.
I just made that up but you can see how it confuses or switches what is necessary for what is sufficient. You can't switch them. Just because grass needs water to be green doesn't mean it doesn't also need other necessary conditions to be sufficient (sun, good manure, etc)
To add to why D is right, democracy is not necessary (not always NEEDED for political freedom) OR sufficient (won't always RESULT in political freedom). Nevertheless, it could still PROMOTE it.
