SS-> WG
It will be great if you could kindly advise.
Thank you.

In this case, we can rely on the sufficient and necessary condition indicator words. Recall:
The only: Sufficient condition indicator
Only: Necessary condition indicator
The stimulus says “only those flowers that smell sweet are worth growing in a garden”.
Since the word “only” comes before “the flowers that smell sweet”, we know that “flowers that smell sweet” is the necessary condition. That leaves "flowers worth growing in a garden" as the sufficient condition.
WG ? SS
I always remember it like this:
Only always introduces the necessary condition:
Only
Only When
Only Where
etc.
Unless it says “the only”. "The only" introduces the sufficient condition.
In other words, “the only” is… THE ONLY exception.
Hope this helps!
