In "by the waters of babylon, before john leaves, he is told that three things are forbidden. which is not forbidden? a. to cross the river b. to go alone c. to go to the place of the gods d. to travel east

The three forbidden things are:

1. It is forbidden to go East.

2.It is forbidden to go to the "Dead Places", unless you're a priest searching for metal.

3. It is forbidden to cross the great river and look at the "Palace of the Gods".

So option B. To go alone is not forbidden.
Hope it helps!
