Now onto @'s statement

(S) Add pennies to the jar until Bob tells you to stop.

(1) obviously accurate translation:

[not] add pennies to jar → Bob tells (has told) you to stop

(2) perhaps less obvious but also accurate translation:

Bob tells (has told) you to stop → [not] add pennies to jar

Why is (2) accurate? Because common sense. You're given instructions: Add pennies to the jar until Bob tells you to stop. Then, Bob tells you to stop. What do you do? If you're following instructions, you stop. That's it. (S) is biconditional.

(3) complete and accurate translation:

Bob tells (has told) you to stop ↔ [not] add pennies to jar

I'm a confused as to why in the Group 3 flashcards answers we had:

[not] add pennies → I tell you to stop

[not] I tell you to stop → add pennies

but JY's #2 above is different (T→/A vs the flashcard's /T→A). Does the order matter? Does which side we choose to negate matter?

Outside of the blossoms vs leaves, is another big reason for A being wrong because it rejects the information we're prompted with, of somebody being seeing both plants at the same time?
