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 ________.

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

We see that the unemployment rate fell from 8 percent in 1881 to 7 percent in 1886. However, the statistics cannot conclude that the number of unemployed people in 1886 was lower than it had been in 1881.

Now, 8 percent of X can be lower than 7 percent of Y if Y > X. We want to look for an option where the value of Y presented is higher than X.

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886
Our percentage calculation does not involve the time employees stay in the job. Eliminate.

(B) The total available work force, including those with and without employment, increased between 1881 and 1886
This says that the value of Y is more than that of X. This gives a valid reason. Keep.

(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881
Our calculation does not involve data from other regions.

(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
As long as then jobs were “replaced”, the employees could be considered employed. We are not considering wages in our calculation.

(E) help-wanted advertisements increased between 1881 and 1886
We are not sure whether an increase in the advertisement has any effect on our calculation.

Answer B

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. 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 ________.

Analysis:
1881 -->1886
unemployment rate: 8% --> 7%
Let say total population: P(1881)-->P(1886)
Conclusion: number of unemployed people wasn't lower in 1886 than in 1881.
which can strengthen the conclusion, if 8%* P(1881) <= 7% * P(1886) => P(1886) >= (8/7) * P(1881) ==> i.e. if total number of people increased from 1881 to 1886, the the conclusion can be strengthen


(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 --> irrelevant: average time can drop, still unemployment number can be lower
(B) The total available work force, including those with and without employment, increased between 1881 and 1886 --> correct: matches w/ analsyis
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881--> irrelevant: some states unemployment rate can be higher in 1886, still overall unemployment rate can be lower & unemployment number can be lower
(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--> irrelevant: we are talking about total unemployed people, so pay is irrelevant
(E) help-wanted advertisements increased between 1881 and 1886--> irrelevant: advertisement can be more because of more advertising facility or others, this has no impact on unemployment number

The unemployment rates in Prelandia fell from 8 to 7 percent in 5 years, but it cannot be properly concluded that the number of people reduced because ______. We need to finish the passage taking into account the information given and find the best logical ending. This is type of CR (Critical Reasoning) questions. Let us analyze each option:

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 - Even though the time spent by employees in any particular job dropped, it does not give the reason to think that it affected the number of unemployed people somehow. Incorrect
(B) The total available work force, including those with and without employment, increased between 1881 and 1886 - This statement supposes that total number of working people increased. In this case, if the workforce increase was significant, the number of unemployed workers could even grow despite the fact that the percentage of unemployed people decreased. Correct
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881 - The information about other states is irrelevant. 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 - In case high-paying jobs were replaced by low-wage service jobs, most probably people had to work at low-wage jobs, and this statement does not explain how the percentage is irrelevant to the total number of unemployed people. Incorrect
(E) help-wanted advertisements increased between 1881 and 1886 - The number of advertisements does not explain how the number of unemployed workers increased. It could have been increase in work places instead. Incorrect

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

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 ________.

Here we need to find the reason why despite the higher rate the number of people who were unemployed was lower.
Notice, that un the first sentence the author uses percentages and in the second he speaks about the number of people.
The first thing that springs in mind is that the population of Prelandia grew. Let's check the answers.

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 ----it does not explain why number of unemployed people was lower
(B) The total available work force, including those with and without employment, increased between 1881 and 1886 ---in line with pre-thinking.
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881 --- this option talks about some mid-western industrial states, but we consider Prelandia as a whole
(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 does not affect the unemployent rate
(E) help-wanted advertisements increased between 1881 and 1886 --- this is absolutely out of scope


The answer is B

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.

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 ________.

Prethinking: Rate fell but number cannot be concluded - as rate is a factor of 2 things "unemployed and total workforce". So total workforce might have increased significantly while unemployed people marginally increased or remained the same.

(A) The average time that employees stay in any one job dropped during the period 1881 to 1886 - Incorrect, as no impact on the rate of unemployment (not considered for arriving at the rate or number of unemployed people)
(B) The total available work force, including those with and without employment, increased between 1881 and 1886 - Correct, in like with prethinking.
(C) In some mid-western industrial states, the unemployment rate was much higher in 1886 than it had been in 1881. We are concerned with unemployment rate and total workforce in entire Prelandia. Intra-country differences will not affect the country's rate or number of workforce
(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 jobs were not lost but replaced so has no effect on the rate or total workforce
(E) help-wanted advertisements increased between 1881 and 1886 - Irrelevant, advertisement has no correction with rate or total workforce in the country

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.

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


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.

Answer (B).

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.
