Answer
If the database is open, then either the system is in its initial state or the monitor is put in a closed state.
Work Step by Step
Lets do, me, and in stand for the propositions.
"The directory database is opened,'' "The monitor is put
in a closed state," and "The system is in its initial state,'' respectively.
Then the given statement reads -iin ___, (do ___, me).
By the third line of Table 7 (twice), this is equivalent to in V (-ido V me).
In words, this says that it must always be true that either the system is in its initial state, or the data base is not opened, or
the monitor is put in a closed state.
Another way to render this would be to say that if the database is open,
then either the system is in its initial state or the monitor is put in a closed state.
