#148 G won’t go unless J goes.

[ok123go123]

G won’t go unless J goes.

Why is it:
g -> j

and not
j -> g


Help is greatly appreciated, thank you

G is reliant on J. J is the necessary and can occur on its own. The sufficient, g in this case, relies on the j to be present and can never appear alone.

Like the commonly used example:

To get an A you must study.
So to obtain an A (aka g) studying is required (j). However, just because one studies does not guarantee an A grade; studying in itself is independent of getting an A grade. J can stand alone, g needs j's presence to appear. Lets say you got an A, well its given that you studied; g -> j.

Studying might get you so far, but the necessary studying (j) is required for a sufficient A grade.

Precisely!
