### accompany-sufficient or necessary indicator?

Hello,

One of LR Question needs a diagram, but I am not familiar with how the word 'accompany' works in a conditional statement.

All immoral actions 'are accompanied by' feelings of guilt.

Should I diagram IAction --> Fguilty?

If the statement was feelings of guilt accompany immoral actions, should I diagram differently?

Please clarify on this Accompany Thank you!

Do not diagram differently. The different wording makes the two statements logically equivalent. It's like when an "if a, then b" is turned into "b only if a." In both cases, the "b" is dependent on "a." In both of your example statements, feelings of guilt are dependent on immoral actions. Focus on which is dependent on the other, not on wording order or anything else.

so,
A "is accompanied by" B = Requires, Needs, depends on
: A --> B
B "Accompany" A = is required, is needed, is dependent on
: A --> B

Correct?

A little bit weired grammatically...maybe I need the better understanding of the word 'accompany' itself though...still confused

I would add to the above that "A accompanies B" and "B is accompanied by A" are the same statement rephrased in the active and passive voices, respectively. Equally, consider "He hit the ball" and "The ball was hit by him." The emphasis might be different, but the meaning is the same.
