"Order of the vertex" - Networks

[99.96]

Question 3 in networks:
In the network diagram, the order of the vertex that represents the ACT is?

What the hell is the order of the vertex?
I thought it was a misprint and it was meant to say degree instead. So i put down B which is apparently correct.

But for clarification, is order of a vertex the same thing as the degree or was it a misprint?

i had no idea either.. i thought it meant the order as in chronologically, so i put E, thinking d=the 4th letter haha

Did the exact same thing.
I'm positive my teacher said something about examiners using the word 'order' instead of degree just to trick some people up...or maybe i just hoped he did.
Either way its correct

i had no idea wtf order was either, but i assumed degree
in hindsight, TM69's answer made more sense, but was wrong
dat luck

Yeah i was thinking that, but something about that just didnt make sense, ended up going with my gut:)

Yeah, I just assumed degree....VCAA mistake?

[Natters]

not a mistake as it isnt unheard of, just an annoying and lame little trick on their part

[Hodgeyhodgey]

Just a different word for degree, sadly. Had me stumped for a little bit and I thought about putting 4, but I didn't change my answer at the last minute like a good little boy and it paid off!

Phew, I just assumed it meant "degree". ):

When I saw that question during reading time, I was like, "Why is there no glossary in my further book?!?!?"
