In a recent study, a building trade group found that there are more fireplaces in the Southeastern portion of the United States than there are in either the Northeast or Upper Midwest. This finding is surprising, given that fireplaces produce heat and that both the Northeast and Upper Midwest are much colder, on average, than the Southeast, where warmer average temperatures mean that the season during which a fireplace could be used is much shorter.

Each of the following, if true, would help to explain the above discrepancy EXCEPT:

A.On average, houses in the Southeast are newer than those in the other two regions and newer houses are more likely to have added amenities, such as fireplaces

B.When outside air temperatures are very cold, fireplaces can actually decrease the temperature in a house by allowing an influx of cold air to come down the chimney when a fire is not lit.

C.Homeowners in colder regions are more likely to have a stove, rather than a fireplace, because a stove produces much more heat while a fireplace is largely aesthetic.

D.Compared with those in the other two regions, many more of the fireplaces in the Southeast use natural gas as a fuel instead of wood, producing very little heat but making them much cheaper and easier to use than wood stoves.

E.Although once an important part of home heating, fireplaces have now largely become status symbols for fashionable homeowners.

It was between D and E and I chose D (and got it wrong :( ). Need help, here's my reasoning:

We need to spot a choice that DOES NOT RESOLVE the paradox. Between D and E, i thought both resolve the paradox to some extend and E did it more. Therefore i marked D.

D.Compared with those in the other two regions, many more of the fireplaces in the Southeast use natural gas as a fuel instead of wood, producing
very little heat but making them much cheaper and easier to use than wood stoves.

-This tells us that in Southeast, the fireplaces were easier and cheaper to use and that is why we have a reason to believe that in Southeast there were more fireplaces than other two areas. Okay, But...
This reasoning is good enough to only a certain extent. Because the underlying reason for using a fireplace in Southeast at first place was still 'to produce heat'. Though it was cheap etc. people still used it for producing heat. Paradox not resolved!


E.Although once an important part of home heating, fireplaces have now largely become status symbols for fashionable homeowners.
-This choice, on the other hand, gives a completely different reason. It says that the temperature was never the reason for the Southeastern poeple to use fireplaces, it was rather a status symbol for them. And therefore, it had nothing to do with the outside temperature of the region (which is the actual reasoning in the argument). Therefore i felt that this choice is resolving the paradox more.

Please let me now where did i falter.

Dear Arhumsid,

I am happy to help!

Remember following points for resolve the paradox questions:

1. These questions generally do not have conclusion
2. These question have at least one premise and one counter premise

Well I would like to analyze answer choice D and E for you.

Argument:

Premise: More fireplaces in the Southeastern portion than either the Northeast or Upper Midwest

Counter Premise: Northeast and Upper Midwest are much colder than southeastern part (hence southeastern would require fireplaces to be used for less duration)


Now come to answer choices:

D.Compared with those in the other two regions, many more of the fireplaces in the Southeast use natural gas as a fuel instead of wood, producing very little heat but making them much cheaper and easier to use than wood stoves.

INCORRECT. It resolves that paradox. As per this answer choice in southeast region people are using fireplaces in place of wood stoves because the fireplaces are cheap.

Well, if this is the case then it resolve the paradox. This testify that higher number of fireplaces utilized by the people are not due to environment temperature but due to other utility (as a wood stoves)

E.Although once an important part of home heating, fireplaces have now largely become status symbols for fashionable homeowners.

CORRECT. It does not resolve the paradox.

OK. your thinking is correct that the fireplaces are used as fashion statement.

But does that resolve the paradox regarding disproportionate high number of fireplaces in southeast. No


Hope this make sense and helpful to you.

Can someone advice why B is eliminated? B only says why northeast or upper midwest has fewer fireplaces but does not mention why south has more fireplaces. All other options deal with both north and south midwest.

Dear hwgmat2015,

Please note that answer choice (B) does not mention any specific locality.

It mentions that:

When outside air temperatures are very cold, fireplaces can actually decrease the temperature in a house by allowing an influx of cold air to come down the chimney when a fire is not lit.

You can conclude from this statement:

- When outside temperature are more cold (Northeast and Upper Midwest) then there could be less number of fireplaces as it (when not lit) will allow cold air in the house

- When outside temperature are less cold (Southeast) then there would less impact of cold air coming into the house from unlit fireplace and hence number could be higher than much colder areas

Hence answer choice B resolves the paradox. Hope it makes sense!!!!

Moreover just evaluate answer choice B and E and see which one makes more sense to you.

Hey thanks WillGetIt!

Something clicked while reading your explanation and i was ready to accept with all heart that D indeed resolves the paradox. I was feeling like this :idea:
Last night i was quite adamant to digest this fact. I think, a good night sleep and your explanation in the morning did the trick ;)

D: Provides a differentiating factor between the two regions-
Fireplaces are cheaper in the Southeast than the other two regions. This reason is a probable explanation for the paradox.

E: Provides one more reason why more people have fireplaces-
fireplaces have now largely become status symbols. This is true for all the regions, Therefore doesn't explain the difference in numbers in one region. Hence, doesn't resolve the paradox.

:thumbup:

B does not resolve the paradox. We have to have new information that explain why SE has more fire places than NE and Upper MidWest do.
Choice E says. It is about the appearance not about cold weather. That explains the discrepancy. I dont know how B is not the answer.

Option B: Without any information on the % of the total time for which the fireplace is left 'on' in very cold temperatures, I'm not sure how this option, however true it may be, resolves the apparent discrapency.

Option E: Not convinced how this can be written off as a possible explanation for the discrepancy when this option implies very clearly that fireplaces have become an obsolete and/or irrelevant factors in heating homes, so very cold places can afford to not have fireplaces anymore??

The option that does not have a differentiating factor between the SE region and the other regions does not explain the discrepancy - the choices that explain the discrepancy must in some way state some difference (or some fact that implies some difference) between the SE and the other regions. All choices except E states such difference. E states that "fireplaces have now largely become status symbols for fashionable", implying fireplaces have become fashionable for people both in the SE region and the other regions. Hence it does not help explain the discrepancy.

Choice E is the correct answer because fireplaces as status symbols applies equally to all regions of the country and does not provide a distinction to explain the paradox of more fireplaces in the warmer region. Choice E, therefore, does not explain the paradox.
Choice A explains the paradox because newer homes are more likely to have fireplaces and houses in the Southeast are newer.
Choice B explains the paradox by indicating that fireplaces may not actually be practical in colder regions because they tend to cool the house when not in use.
Choice C explains the paradox with the fact that stoves are more useful in colder regions and are preferred over fireplaces in those regions.
Choice D explains that fireplaces in the Southeast often use gas fuel, which makes them easier to use, but provides little heat for cold regions.

VERITAS PREP OFFICIAL SOLUTION:



Correct Answer: E

The four incorrect answers will explain the paradox of more fireplaces in the Southeast, which is a warmer region. Choice E, the exception, is the correct answer because fireplaces as status symbols applies equally to all regions of the country and does not provide a distinction to explain the paradox of more fireplaces in the warmer region. Choice E, therefore, does not explain the paradox. Choice A explains the paradox because newer homes are more likely to have fireplaces and houses in the Southeast are newer. Choice B explains the paradox by indicating that fireplaces may not actually be practical in colder regions because they tend to cool the house when not in use. Choice C explains the paradox with the fact that stoves are more useful in colder regions and are preferred over fireplaces in those regions. Choice D explains that fireplaces in the Southeast often use gas fuel, which makes them easier to use, but provides little heat for cold regions.
