Practice Question
Question No.: CR 139
Page: 534

Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.

Sharon: But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed. So at any given time if a person knows approximately 50 workers, 1 or more will very likely be unemployed.

Sharon's argument relies on the assumption that

(A) normal levels of unemployment are rarely exceeded
(B) unemployment is not normally concentrated in geographically isolated segments of the population
(C) the number of people who each know someone who is unemployed is always higher than 90% of the population
(D) Roland is not consciously distorting the statistics he presents
(E) knowledge that a personal acquaintance is unemployed generates more fear of losing one's job than does knowledge of unemployment statistics

Note: There is another question (conclusion question) which is based upon the same argument. For reading and further discussion on that question, please use the following link:

Sharon's argument relies on the assumption that
1. normal levels of unemployment are rarely exceeded.
2. unemployment is not normally concentrated in geographically isolated segments of population.
3. the number of people who each know someone who is unemployed is always higher than 90% of the population.
4. Roland is not consciously distorting the statistics he presents
5. knowledge that a personal acquaintance is unemployed generates more fear of loosing one's job than does knowledge of unemployment statistics

It should be B. Imagine you have the following situation:

a town of 50,000 has 100% unemployment, and no one in this town speaks to anyone else in the country
the other 950,000 people in the country, or 95% of the population, all have jobs

Then only 5% of your population would know anyone who was unemployed - the 5% in the isolated town full of unemployed people. Sharon's argument assumes that unemployment is spread fairly equally across the population.

B it is
A) This is not an assumption and will not affect the argument/conclusion given.
B) negate this one and you get:
unemployment is normally concentrated in geographically isolated segments of the population
What is the implication of the above? If unemployment is concentrated in certain areas, how can we say that if someone who knows 50 persons will very likely know more than 1 person who is unemployed?
Let's take a simple number example. Country A has two cities: X and Y
City X: population = 100 --> 10 are unemployed
City Y: population = 100 --> 0 are unemployed
Total unemployment rate for country A: 10/200 = 5% --> as claimed by Sharon
As you can see in my example, unemployment is concentrated in a geographical location: city X
Hence, if that someone who Sharon is talking about lives in city Y, is it right to say that that person is likely to know more than one person who is unemployed? No, because that person lives in a city where there is no unemployment whatsoever.
Conclusion: We need to assume that unemployment is not isolated in geographically isolated segments of the population. If not, the argument falls apart.

A.

I am getting this by process of elimination.

(B) unemployment is not normally concentrated in geographically isolated segments of the population -- Geographical isolation is not discussed in the argument.

(C) the number of people who each know someone who is unemployed is always higher than 90% of the population -- General statement

(D) Roland is not consciously distorting the statistics he presents
-- This is not the assumption

(E) knowledge that a personal acquaintance is unemployed generates more fear of losing one's job than does knowledge of unemployment statistics -- General statement

I tend to differ with Paul. My answer is choice A.

Sharon's statement starts with the qualifier "Moderate level of employment is 5 percent...".
Whole of his arguement is based on the fact that these are very Normal and not alarming

It can only be true if the underlying assumption is A, hence the answer.
B is close but the there are no premises that hint difference in geographies.
All the other options can be ruled out

Sharon's argument relies on the assumption that

(D) Roland is not consciously distorting the statistics he presents
(E) knowledge that a personal acquaintance is unemployed generates more fear of losing one's job than does knowledge of unemployment statistics

Hightlight below
Sharonâ€™s argument assumes that people are generally similar in how likely they are to have among their acquaintances people who are unemployed. Since heavy concentrations of unemployment in geographically isolated segments of the population would produce great differences in this respect, Sharonâ€™s argument assumes few, if any, such concentrations. Choice B is therefore the best answer. If normal levels of unemployment were exceeded relatively frequently, and if Rolandâ€™s figure of 90 percent were an exaggeration, Sharonâ€™s argument would be unaffected, so choices A and D are incorrect. At exceptionally low
levels of unemployment, Sharonâ€™s argument suggests that choice C is likely to be false, so C is not assumed. The fear of losing oneâ€™s job is not part of Sharonâ€™s argument, so choice E is incorrect.

After I read the explaination, I still don't understand. Can someone bring me a better view? Thanks.

Hi,

You didn't include the explanation, so I hope this helps. I'd choose B.

A) this answer is out of the scope of the question.
B) this is the best answer. My first thought when reading S's response was that she was assuming that unemployed people are distributed evenly throughout the population. This would be required for her interpolation of the statistics to be true. B says nearly this, that if the unemployed aren't distributed evenly geographically, then her response isn't valid.
C) This answer is out of scope, and also contradicts R's facts, which we can assume are true for the purposes of the question.
D) Roland's facts don't figure into her response, only her interpretation so this answer isn't right.
E) This response is unrelated to the question.

B it is ---

(A) - doesn't convey any meaning
(C) that's what first person says. so it's contradictory.
(D) out of scope
(E) out of scope.

a tough one....

Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.

Roland here gives a big picture. He starts the sentence with "The alarming fact" which means he is making it big and adds a figure 90% of population knows someone who is unemployed...

Sharon: But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed. So at any given time if a person knows approximately 50 workers, 1 or more will very likely be unemployed.

But Sharon plays it down by saying normally umemployment is only 5%. But he ends the statement by 1 or more will very likely be unemployed.

I will go for 'A'

Use the POE method.

A) Sounds OK because Sharon is not alarmed with Roland's say. Lets
keep this aside.
B) Sounds a little away from the passage because Sharon does not
assume this and talks nothing about the geograpical area. Option (A) is
still the best one.
C) This is what Roland says, and not Sharon. This also uses the
word "always" which is generally not the right choice to make.
D) Sharon does not mean anything like this in her say. Out of scope.
Remember (A) is still our best choice.
E) No where in the conversation does it imply about losing one's job. This
choice is trying to go way beyond the discussion. Hence
cannot be the right choice.

Leaving us with Choice (A).

Will go with B.
Roland argues that 90% of people report that they know somebody unemployed. Whereas Sharon argues that the unemployment rate is only 5%. Hence if a person know 50 other persons..... one of them could be unemployed.
Now she is assumping that unemployement is not present in specific areas and is spread out to different geographical regions such that people are acquainted with different class of people.

Roland is freakin out that 90% of the people in Xanadu know someone in that country who is unemployed.

Sharon is asking Roland to chill out because that stat presented by Roland means that normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed. So, if a resident of Xanadu knows 20 people, 1 of them will most likely be unemployed.

Now this is only possible if the unemployed people are scattered evenly across the country.

Thats what I made out of it

Still cannot accept 'B'

'B' - unemployment is not normally concentrated in geographically isolated segments of the population ..
In other words they are spread across.
This, I believe, is a very generic statement and totally out of context. Morever the statement usesis not normally which will not fit into an assumption

Sharon is responding to Roland's statement and why would she talk some thing totally irrelevant to Roland's statement. [/b]

OA is B.

OE:

Sharon makes an equalizing statement about people and their acquaintance when she posits that, if an average person knows 50 workers, at least one of them is likely to be unemployed. Sharon's generalization must assume that this is the case eually throughout the country and that unemployment is not concentrated in some geographically isolated areas.

E. knowledge that a personal acquaintance is unemployed generates fear of losing one's job than does knowledge of unemployement statistics.
