Editorial: The mayor plans to deactivate the city’s fire alarm boxes, because most calls received from them are false alarms. The mayor claims that the alarm boxes are no longer necessary, since most people now have access to either public or private telephone. But the city’s commercial district, where there is the greatest risk of fire, has few residents and few public telephones, so some alarm boxes are still necessary.

Which of the following, if true, most seriously weakens the editorial’s argument?

(A) Maintaining the fire alarm boxes costs the city more than five million dollars annually.
(B) Commercial buildings have automatic fire alarm systems that are linked directly to the fire department.
(C) The fire department gets less information from an alarm box than it does from a telephone call.
(D) The city’s fire department is located much closer to the residential areas than to the commercial district.
(E) On average, almost 25 percent of the public telephones in the city are out of order.

Will go with B
If there are auto fire alarms then there is no need for manual fire alram boxes used to call the fire dept. Hence even though there are no pub phones in comm district, the comm district is still safe without the manual fire alarm boxes

I think E is incomplete
The arg says "since most people now have access to either public or private telephone" whereas E talks about only public telephones

B for sure ! We want to find something that weakens this particular stance "City commercial buildings need alarm boxes because they have no phopnes"

(B) does just that. If the building all have automatic fire alarm systems that are linked directly (note the key words here) to the fire department, then fire boxes are completely redundant because no one is going it, ever.

In (E), tellign us 25% of the public telephones in the city are out of order does not dispute the argument that alarm boxes are not required.

I have been fallen into trap answer B.

I chose B because B support the fact that why alarm box is not required. By now I have realized that argument is about why alarm box is required in commercial building.

Wilfred,

What has to be weakened here? Mayor plans to deactivate the city’s fire alarm boxes or the commercial or necessity of alarm boxes in city’s commercial district? I am confused. Opted answer E assuming that since public telephones are not necessary, alarm boxes should be present.

Hi ,

Basically the mayor claims that the alarm boxes are not necessary but the author of the editorial adds on that the alarm boxes are necessary in commercial spaces.Thus to undermine the author's argument we have to understate that the commercial spaces also do not need any alarm boxes.

Lets look at the options below:

(A) Maintaining the fire alarm boxes costs the city more than five million dollars annually.Out of scope.We do not know how the city's expenses are related to the alarm boxes.
(B) Commercial buildings have automatic fire alarm systems that are linked directly to the fire department.CORRECT as this provides a reason as to why the commercial buildings dont need an alarm box.
(C) The fire department gets less information from an alarm box than it does from a telephone call.
The fire department is still alerted either from an alarm box or through the telephone call.The information is passed on to the fire department.Moreover it does not differentiate between normal spaces and commercial spaces.
(D) The city’s fire department is located much closer to the residential areas than to the commercial district. : Out of the arguments scope.
(E) On average, almost 25 percent of the public telephones in the city are out of order.: out of scope of the argument

Can someone also explain a step by step approach to solve this question please?

Hi prep,

I am happy to respond.

Conclusion of the above argument - some alarm boxes are still necessary.
Reason as suggested from the argument - the city’s commercial district, where there is the greatest risk of fire, has few residents and few public telephones. SO, this goes against the mayor's plan/claim. So, the alarm boxes will still be necessary for the city's commercial district.

Option C - The fire department gets less information from an alarm box than it does from a telephone call.
This option is stating the advantage of the telephone calls over alarm boxes. That's good. But as we already know from the argument that the city’s commercial district, where there is the greatest risk of fire, has few public telephones, so instead of the advantages of the telephone calls, we still need the alarm boxes. So, this option makes the argument stand as it is. Therefore, incorrect.

Step by Step approach -
Its a weaken question, so,

1. Firstly, look for the conclusion.
2. Look for the premises which makes that conclusion hold. (Then, try to predict an answer. That will solidify your reasoning for the argument.)
3. Look for an alternate cause or something that weakens the conclusion along with the reasoning that is leading that conclusion to hold.

If we look at the correct option for this question,

Option B - Commercial buildings have automatic fire alarm systems that are linked directly to the fire department.
This provides an alternate reason which weakens our conclusion of requiring the alram boxes still. So, correct.

Hope you got the soultion for your question.

Detailed solution for this question :

The editorial argues that fire alarm boxes remain necessary in the commercial district, because the specific alternatives to the alarm boxes to which the mayor refers-public and private phones-are not common there. The question asks you to identify a weakness in the editorial’s argument in favor of keeping alarm boxes in the commercial district.

Choice B is the best answer. If commercial businesses use a different alternative-alarm systems connected to the fire department-then the editorial’s conclusion is not well supported.

Neither choice A nor choice C gives any reason to think that the alarm boxes are not necessary, although both choices prove grounds for deactivating the boxes if they are no longer necessary.

Choice D emphasizes the need to make sure that fires in the commercial district are reported quickly and does not weaken the editorial’s argument.

If public telephones are often out of order (choice E), there is more, rather than less, reason to think that the alarm boxes are necessary.

B indicates that there is exists an alternate mechanism, which alerts the fire department even without the presence of fire alarm boxes. Hence the Mayor's conclusion is strengthened and the editorial's conclusion is weakened.
