can I modify the question to what it should be?
as a teacher at night I can see ,whets the problem

in line..

I think the question should be:
what induced voltage the panel version X brand Y that we have studied will
tolerate at its input,before giving false alarm or trouble?

and this one:
whats the unit of measure for attenuation?

this one is better?
Under the code X of country Y that we studied,A detector installed in a
residence that would meet U.L. requirements would be?

or this would make sense....
4.During troubleshooting, of the power supply of the panel X,the voltage
should be checked...

Humm this one is special,and need a total workout...
Where should we never plug our transfo?(you can select more then one answer)

Another thing about local electrical code..

What is the minimum temp variance needed to trip a passive infrared motion
detector,model X Brand Y

And the last
In a 12 volt system, what voltage should be read across a closed switch with
a 6k ohm resistor,if the sensing circuit use the same impedance,as the end
of line resistor?

And the answer cannot even be clear,cause if we read the last question
(before or after the modification)

"what voltage should be read across a closed switch" if the switch is close
and we mesure the voltage across it..the answer is?  NADA nothing,zip
,zero..the damn switch is closed...............

those question are so badly form that even someone speaking another language
(like me) can point that total unusefuleness of it..
