1351

[asandova]

F is either before G or after H, but not both.

I chose

G-F-H or H-F-G

but it is saying that the correct answer is

F < G& H or G & H > F

am i just not seeing something? or misunderstanding the diagram?

i also had question #1353, which had the same language but used the variables J, M, and N but I got that one wrong too

In the answer you chose (G-F-H or H-F-G) can you see a situation in which F is before G but not after H (or F is after H but not before G)?

The issue is that that answer violates the "but not both" part.

Got it?
