Using
egmat's falsification method to arrive at assumption, we can find what can strengthen this argument:
Premise: Everyone now owns a phone and they can call the fire department in emergency anytime from their personal telephone.
Conclusion: Removing the public alarm boxes will reduce the number of prank calls.
Falsification questionIn What scenario: Removing the public alarm boxes will not reduce the number of prank calls.
Given that: everyone now owns a telephone
One scenario can be:
- When people are doing prank calls from their personal phone as well.
So assumption can be negation of above scenario
Assumption: People won't do prank calls from their phone. Anything around that will strengthen our conclusion.
Going through the answer choices:
(A) The fire department traces all alarm calls made from private telephones and records where they came from. -
Damn, that's exactly what we were looking for. It connects with our assumption and this should be the answer but let's go through all answer choices and reject each of them.(B) Maintaining the fire alarm boxes costs Springfield approximately five million dollars annually. -
This statement doesn't even relate to our conclusion(C) A telephone call can provide the fire department with more information about the nature and size of a fire than can an alarm placed from an alarm box. -
How can a telephone call provide this much of information and how does it relate to the conclusion of removing boxes
(D) Responding to false alarms significantly reduces the fire department's capacity for responding to fires. -
That's actually strengthen the conclusion but the biggest flaw is that what if people start calling from their personal phone and have prank calls(E) On any given day, a significant percentage of the public telephones in Springfield are out of service. -
We don't have anything to do about the number of telephones which are out of serviceHence,
A is the best choice.
