well we know the answer is C, but its the most correct out of the 4, not
necessarily the ultimate correct answer.

>>>It's possible, but not the only possibility. Therefore you
can't answer A.
And if you're not certain, you can't answer the question. Because this
is the Oracle OCP exam. The thing that you've studied night and day
for. Everything you learned in the two-night class preparing you for
database administration and nuclear physics. This is crunch time, baby -
right or wrong? You make the call. Pressure's on. Which will
it be? What if this is the question that will put me under that
passing grade. A or C? A or C? Which will it be? What
will I do????? You want the truth? You want the truth? You
can't handle the truth!!!!!!!!!!!!!
I'm heading back to the espresso machine now...

there are two subjects in the IN set and at least 2 teachers have to teach
each subject, 2*2=4. Basic mathematics: at least 4 teachers will get a raise.
