Homeowner Representative: Statistics show that burglars often target houses that appear unoccupied. Therefore, when homeowners are away from their homes for several days, we recommend that they leave lights on, to give the impression that the house is occupied.
Crime Expert: The same lights continuously on all night long with no change give a potential burglar a clear signal that the house is unoccupied.

The Crime Expert uses which of the following techniques in responding to the Homeowner Representative?

A) calling into question an unstated assumption
B) pointing out an undesired effect of a recommendation
C) presenting new evidence that calls the conclusion into question
D) explaining that a reputed effect is actually a cause
E) demonstrating that the conclusion is true, but not for the reasons cited

OPTION A - INCORRECT
Well, this isn't exactly the technique that the crime expert is trying to achieve. The crime expert's response is an unstated assumption but it shouldn't be called into question because it doesn't benefit the home-owner representatives argument.

OPTION B - CORRECT
Putting the lights on seems like a good recommendation made by the home-owner representative to keep burglars away but the crime expert used the technique of pointing out an undesired effect about that recommendation, which is "the same light continuously on all night long with no charge give a potential burglar a clear signal that the house is unoccupied"

OPTION C - INCORRECT
This cannot serve as a new evidence because the same entity is still being referred to, which is "putting on the light", and it doesn't call the conclusion into question.

OPTION D - INCORRECT
Here, we do not know if the home-owner representatives recommendation is a reputed effect because it is just a recommendation.

OPTION E - INCORRECT
The crime expert wasn't trying to prove that the conclusion is true even with the reason that he gave.
