he unemployment rate in Prelandia fell from 8 percent in 1881 to 7 percent in 1886. It cannot, however, be properly concluded from these statistics that the number of unemployed people in 1886 Prelandia was lower than it had been in 1881 because ________.
Conclusion:

Even when the statistics shows that the employment rate has decreased, it cannot be concluded that total unemployed population has gone down. We need something that will explain this paradox

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886- Incorrect. They may be not staying in one job but might be be shifting jobs hastily. this does not affect the unemployment rate, even if we assume that they leave work completely and stay unemployed, the percentage must have gone up
(B) The total available work force, including those with and without employment, increased between 1881 and 1886- Correct. If the total work force(employed + employed has gone up), then even if the rate has gone down, The number of people can be same or lower. Hence the statistics could be wrong
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881- Out of scope.We are not concerned about other states
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers-Incorrect . If this was the case, it could have been reflected in the percentages above
(E) help-wanted advertisements increased between 1881 and 1886- Irrelevant. Increase in just advertisements doesn't necessarily they have all been posted by unemployed people and their corresponding number has also increased.

Pre-think: So there is a percentage change, but what about the total number? If the total number rises more than the influence of percentage change, that can be the answer on the question. 8%*total number ago > 7%*total number now?

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886. WRONG. Don't have a straight influence on the quantity of people that have a job.
(B) The total available work force, including those with and without employment, increased between 1881 and 1886. RIGHT. That's about the total number of people.
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881. WRONG. Don't influence on the quantity of people that have a job at all.
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers. WRONG. Displacement doesn't mean change in total number.
(E) help-wanted advertisements increased between 1881 and 1886. WRONG. We can't say that it is influenced by raise of total number of people.

The unemployment rate in Prelandia fell from 8 percent in 1881 to 7 percent in 1886. It cannot, however, be properly concluded from these statistics that the number of unemployed people in 1886 Prelandia was lower than it had been in 1881 because ________.

Pre-thought
because --- is the reason we have to give for the inference
employment rate decreased from 8 to 7 --> cannot conclude the number of unemployed people in 1886 was lower than 1881

lets say 1000 people are eligible for employment in 1881---> 8*1000 = 80 are unemployed

in 1886 --> 7*(1000+x) =70+7*x ---> where x is the rise in total population of eligible for employment
So we don't know x so we can't infer there is a rise or drop in the unemployed men


(A) The average time that employees stay in any one job dropped during the period 1881 to 1886--Incorrect
the time employee stay in a job is not necessarily the reason as one might get a job in hand and changed

(B) The total available work force, including those with and without employment, increased between 1881 and 1886-Correct
exactly as per our pre though --> total increase then the no.of unemployed may remain same decrease or increase --This is the conclusion of the argument


(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881-Incorrect
No comparison is in the context of the argument ,this so comparison cannot be the conclusion of the argument

(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers-Incorrect
high pay jobs were replaced by low pay resulting movement of workers with in Prelandia or outside is not mentioned--so more confusion cannot be the reason for conclusion

(E) help-wanted advertisements increased between 1881 and 1886-Incorrect
advertisement for employment increased doesn't mean no.of job increased , one could repeatedly do many
and this doesn't mean unemployed decrease

This is an easy question. To answer this question you need to follow the argument closely. We know that larger percentages do not necessarily mean larger numbers, because there can be a difference in the total number.
This is what we are looking for in the argument. Let's get down to POE.

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886
This is irrelevant as we are not told about the average time.

(B) The total available work force, including those with and without employment, increased between 1881 and 1886
This is correct, there could be fluctuations in the workforce Due to which the number of unemployed could have been the same .

(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881
We again cannot be sure of this. To validate it we would need all the stats. Hence incorrect.

(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers
Again we cannot be sure of this as well. The argument doesn't make differences between high paying and low paying.

(E) help-wanted advertisements increased between 1881 and 1886
This is irrelevant to the argument.

Hence the correct answer is b. PS this is a very tested pattern on the GMAT.

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886
This does not impact the unemployment rate.
(B) The total available work force, including those with and without employment, increased between 1881 and 1886
if the total number of people increased than we cannot conclude this finding.
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881
mid western industry is out of scope.
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers
The large number of people working had left the job and migrated/displaced and this led to reduction in the number of people avaliable for that job and also those looking to get that job. Also those with low skill took up new job opportunity and this lead to this finding.

(E) help-wanted advertisements increased between 1881 and 1886
the advertisements are irrelevant to the statistics

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886Doesnt impact unemployment
(B) The total available work force, including those with and without employment, increased between 1881 and 1886
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881Statement talk about overall. Individual does not matter
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workersUnemployment does not consider it as factor. Be it high paid or low paid employment rate is not impacted
(E) help-wanted advertisements increased between 1881 and 1886Irrelevant

Unemployment can only increase in number despite decrease in percentage if the total number has increased
Lets take an example
lt initial population be 100 . 8% of 100 = 8
now new population be 1000 . 7% of 1000 = 70
this shows that despite decrease in percentage. total number increased.
B is the exact definition of this exception
Hence B is the answer

It is Given that % decreased but can't be concluded that number has decreased.
As per prethinking, population might have increased.
Which is option B

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 - Incorrect. Out of scope as average time that employees stay in any job is not discussed at all in argument. hence it is irrelevant.
(B) The total available work force, including those with and without employment, increased between 1881 and 1886 - Correct. if total work force has increased then 7% of higher number can be greater than 8% of lower number. Hence we can't say with surety that no of unemployed youth has decreased.
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881 - Incorrect. Out of scope. The argument does not concern itself with any data related to mid western states. Hence irrelevant to argument.
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers. Incorrect. Out of scope. The argument does not concern itself with high-paying industrial jobs to low paying job related displacement. This will just change type of job and will not have impact on unemployment numbers.
(E) help-wanted advertisements increased between 1881 and 1886. Incorrect. This data does not help in evaluating unemployment number change from 1881 to 1886.

IMO B:

The initial part of the sentence talks about percentages. later part represents actual numbers.
When this is the case, we usually need to look for the choice which shows that the number of people increased between 1881 to 1886.
B does that by telling that the available work force increased. so IMO B is the right answer

The unemployment rate in Prelandia fell from 8 percent in 1881 to 7 percent in 1886.
Here, the argument compares unemployment rate in terms of percent decrease without any reference to the exact number of people involved.

It cannot, however, be properly concluded from these statistics that the number of unemployed people in 1886 Prelandia was lower than it had been in 1881 because ________.
It is only possible when total number of available work force increased for the given period.

B is the clear winner.

IMO B

The argument states that,
1. Unemployment rate in 1881 is 8 percent > Unemployment rate in 1886 is 7 percent
2. The statistics can not conclude that, no. of unemployed people in 1881 > no. of unemployed people in 1886

Pre-thinking: Clearly we only know the rate has dropped, not the number, So if the no. of working/not working ppl in 1881 was 100, and the no. of working/not working ppl in 1886 was 1000, then no. of unemployed ppl in 1881 was 8, which is much more lower than no. of unemployed ppl in 1886, i.e., 70

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 - The duration an employee spends in job is not relevant here, we are looking for numbers of employees

(B) The total available work force, including those with and without employment, increased between 1881 and 1886 - Correct, in line with our pre thinking

(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881 - Other states are out of scope

(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers - We are not concerned about high/low wage or the no. of jobs. We are dealing with no. of working/not working ppl

(E) help-wanted advertisements increased between 1881 and 1886 - Irrelevant

B has to be the right answer.

The total available workforce, including those with and without employment, increased between 1881 and 1886----> THIS SAYS THE TOTAL NUMBER INCREASED IN SPITE OF DECREASE IN EMPLOYMENT RATE.

IMO B.

Premise: Unemployment rate has fallen from 8 % in 1881 to 7% in 1886. But this does not translate to a decrease in unemployment.

We need to find an argument which supports this stance-

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 -->They would still be employed and would not provide strength to the author's claims. Hence this is incorrect.
(B) The total available workforce, including those with and without employment, increased between 1881 and 1886--> This is correct. If the work force has increased, that means 8% of x will be lesser than 7% of 2x and hence provides strength to the argument.
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881 --> Irrelevannt. and would not provide strength to the author's claims. Hence this is incorrect.
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers--> People were still employed and the rate would have decreased. Hence this is incorrect.
(E) help-wanted advertisements increased between 1881 and 1886 --> Irrelevannt. and would not provide strength to the author's claims. Hence this is incorrect.

So the question is saying that though the unemployment rate in Prelandia fell from 8 percent in 1881 to 7 percent in 1886, if the actual figure of unemployed people was lower in 1886 compared to 1881 was not concluded properly - the rate decreased may not suggest the actual reduction in number but THE CONCLUSION IS SAYING THAT "It cannot, however, be properly concluded from these statistics that the number of unemployed people in 1886 Prelandia was lower than it had been in 1881 because ________"........why it cannot be properly drawn -

The unemployment rate in Prelandia fell from 8 percent in 1881 to 7 percent in 1886. It cannot, however, be properly concluded from these statistics that the number of unemployed people in 1886 Prelandia was lower than it had been in 1881 because ________.

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 - May be they switch jobs more frequently during the period 1881 to 1886, but they remained employed in other organizations as well; it is not what the argument is trying to justify.
(B) The total available work force, including those with and without employment, increased between 1881 and 1886 - Available workforce increased, rate of unemployment decreased then surely the number can vary but what my point of view is the actual figure of total workforce is unknown, we discard it .
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881 - Not in scope of the argument, DISCARD
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers- This in my thought is interesting as if the high paying jobs are now replaced with low-wage service jobs in 1886, the resulting displacement of hundreds of thousands of workers that creates a major confusion for the author to draw the conclusion properly it is saying the jobs are replaced (whether it is high paying or low wages we dont bother) but the employees are not terminated; IMO this is correct.
(E) help-wanted advertisements increased between 1881 and 1886 - Who cares, just ignore not, not in line with the argument stated.

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886: It does not tell us about the number of employees, so could not be a reason.
(B) The total available workforce, including those with and without employment, increased between 1881 and 1886: This is true. At least we know that the number of people has increased, thus it can be a reason.
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881: This is irrelevant regarding the paragraph. This does not give a clear picture of the whole industry and people working in them.
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in a displacement of hundreds of thousands of workers: This is again cannot be a reason. If low wages jobs are there then many people may join them, or may not. It does not give a clear picture of increasing or decreasing numbers.
(E) help-wanted advertisements increased between 1881 and 1886: This cannot be a reason for the unemployment rate.

IMO the answer is B.

fact: uRate decreased from 8 to 7 % between a period;
con: that the decrease in uRate "doesnt mean (not certain)" the NUMBER of unemployed also decreased between the same period;
asum: y cant we conclude that the NUMBER of unemp was lower in the same period that the PERCENTAGE of unemp decreased?

b-if the rate was 8% of a small workforce and fell to 7% of a huge workforce, then, the number of unemp could have INCREASED in the period.

Premise

There is a decline in unemployment (by %)

Conclusion

However, cannot conclude that the actual number of unemployed workforce diminished since.... (maybe total workforce increase in that period?)

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 - average time it is irrelevant
(B) The total available work force, including those with and without employment, increased between 1881 and 1886 - Total workforce increase so, a reduction in the percentage does not assure that there will be a reduction in the unemployed people number
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881 -other states, irrelevant
(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers -replace of high for low wage jobs is irrelevant
(E) help-wanted advertisements increased between 1881 and 1886 -we do not care about advertisements, so irrelevant

(B) is our answer.

After reading argument.


It comes straightway if population increases then we can reason it

Only option B states it in a very unique way !

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886

We have nothing to do with time.!!

(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881

It can be case that in some other cities rate is very much higher compared to that of these cities .


(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers

Again this is improper reasoning

Out of context

(E) help-wanted advertisements increased between 1881 and 1886


This is also.completely out of context

B wins

A IMO

Here are my reasons for each option

The unemployment rate in Prelandia fell from 8 percent in 1881 to 7 percent in 1886. It cannot, however, be properly concluded from these statistics that the number of unemployed people in 1886 Prelandia was lower than it had been in 1881 because ________.

Clearly we need to come up with a reason to prove that the number of unemployed people in 1886 did not decrease from 1881.

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886
This looks good. This option says the average length of employment decreased in 1886. This signifies that people actually had a lot of temporary jobs in 1886 as compared in 1881, so it is possible that more people would have been unemployed when their temporary jobs were over.

(B) The total available work force, including those with and without employment, increased between 1881 and 1886
Incorrect. If total available work force had decreases from 1881 to 1886, and unemployment rate also reduce to 7%, then the number of unemployed individuals should have dropped as well.

(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881
Irrelevant. We are looking at unemployment in the entire country, not geography specific.

(D) Many of the high-paying industrial jobs available in 1881 were replaced by low-wage service jobs in 1886, resulting in displacement of hundreds of thousands of workers
Incorrect. Wages are irrelevant.

(E) help-wanted advertisements increased between 1881 and 1886
Incorrect. "help-wanted" ads could be anything, including volunteering jobs. Even if they are paid jobs, it shows 1886 had more jobs than 1881 so it actually weakens the argument.

IMO :B
only way that rate decreased and unemployment rate didn't is if population has increased either working or non working, or some can be non working.
Option B gives that idea that work force has increased
