I see some ambiguities there, probably the worst is

   Now that we know what items are, give a precise definition of the
   verbs "," and "+/"


http://www.jsoftware.com/help/learning/02.htm  has in section 2.5.2 -

Now we can say that in general (x , y) is a list consisting of the
items of x followed by the items of y.

Now we can say that in general +/ inserts + between items of an array.

... so I was shooting for an explanation of , and +/ in terms of items
just like above.

If I were taking this test, I would waste some time wondering if you
meant

[1] Describe the monads , and +/ in terms of the items of their arguments.
[2] ditto but for the dyads

Oh, that's a good point I never thought of the fact that , has both
monadic and dyadic cases..

Now I know how Henry Rich felt when I was complaining about "J for C
Programmers" :)
