Another Kaplan CR

by davy420 » Tue Nov 04, 2008 9:24 pm
A survey recently revealed a high correlation between a household level of education and its library. Specifcially the more years of college and graduation school education recieved by the household members, the more books in the household library. The survey also indicated that the higher the education level of the house hold the greater the percentage of books that are not works of fiction in its library.

Which of the following can be properly inferred from the survey cited above?

A. People with higher levels of education prefer reading nonfiction to work of fiction.

B.Household with low education level generally own more works of fiction than do household with higher education levels.

C.House with lower levels of education generally own more works of fiction than nonfiction

D.The higher the education level of household the fewer works of fiction owned by the household

E.Household with high education level generally own more nonfiction books than do household with low education

Can somebody explain why D is not the answer? thanks

Okay are you trading your explanation with OA ?

Why don't you simply explain what makes E a better choice, so we can all learn from each other ?

A. People with higher levels of education prefer reading nonfiction to work of fiction.

Preference is not stated.



B.Household with low education level generally own more works of fiction than do household with higher education levels.

This question involves percents, NUMBERS are trap. We don't know whether they have more or less books.



C.House with lower levels of education generally own more works of fiction than nonfiction


Again NUMBERS can not be inferred from percents


D.The higher the education level of household the fewer works of fiction owned by the household


It explains a co-relation, which is implied in the stimulus. I will choose D


E.Household with high education level generally own more nonfiction books than do household with low education

Same thing..we can't compare NUMBERS.

Can somebody explain why D is not the answer? thanks

@logitech

sure..
here it goes..

premise 1: A survey recently revealed a high correlation between a household level of education and its library. Specifcially the more years of college and graduation school education recieved by the household members, the more books in the household library

premise 2: The survey also indicated that the higher the education level of the house hold the greater the percentage of books that are not works of fiction in its library

according to premise 1,

Household with high education level ===>> more books in library(than low education)

According to premise 2,

higher the education level of the house ==>> gr8er % of non-fic books.

from 1 and 2..
Household with high education level ==>>>gr8er % of non-fic books

explanation:
accor. to 1 household with higher education will have more books than low educated household..

and as % of non fiction books will be more ,As E says...

Household with high education level generally own more nonfiction books than do household with low education

Also,take numbers..
higher education household = 100 books
lower .... = 50 books

non fiction books % for higher educated is more..thus they will have more books in their library, generally.

I hope this helps...

I generally ask for OA so that i dont spend time to explain whats wrong, :wink:

I apologize if that goes against the rules of the forum.!!

Thank you raunekk. I believe that when we explain something, whether it is correct or not, we learn so many things from them and how other people look at the way we think.

I appreciate your help and knowledge you are bringing to this forum.

Sorry about that guys the OA is E

I don't understand how you can infer E (Household with high education level generally own more nonfiction books than do household with low education) when the stem does not mention anything about household with low education.

That is why I picked D

many a times i get stuck up with an inference question..
then..
i generally choose an option on the basis of the strength of the language and ten try to analyse..
In,
D.The higher the education level of household the fewer works of fiction owned by the household

The percentage is less...not the number of books...

if he has around 10,000 books....so then even if its 10% ..he will have 1000 fiction books...thus even if the percentage is less,,there is no surity that the books will be fewer or not..

@davy420
E Household with high education level generally own more nonfiction books than do household with low education...

it doesnt just talk about household with low education but also abt Household with high education ..there is a comparison,, so i think u shouldnt ignore it...

if it wud hav talked just abt low education household.. then there wud hav been a problem...

thanks,

I see I see what D is saying is that there are fewer fiction books but we can't compare that with nonfiction books because there can be more fiction books than non fiction.

But then isn't B and E saying the same thing

B and E are different

(we know HE has more # of books than LE and that % of non fiction for HE is greater than that for LE)

taking raunekks example

HE: 100 books (say 20% non fiction) gives 80 fiction, 20 non fiction
LE: 50 books (say 10% non fiction) gives 45 fiction, 5 non fiction
so, HE has more fiction then LE, B is not neccessarily true
HE has more non fiction (this is what E says)

E is right because E says about percentage

D is wrong because D says about level which is not mentioned is the stimulus
