If the number of televisions sold in Borodia has not changed, and the number television assemblers in Borodia has gone down, this can mean only two things.

1. The reduced number of assemblers in Borodia means lesser TVs produced in Borodia. The difference is then made up by importing TVs from Vernland
2. The reduced number of assemblers in Borodia are more productive now than they used to be - and they are able to produce the same number of televisions as earlier.

1 is stated explicitly in the stimulus. Lets look at the options to see if we can find 2, or a better assumption, somewhere.

(A): This is not an assumption. It is possible that the assemblers in Vernland are more productive, and for example one assembler in Vernland can produce twice the number of TVs produced by one assembler in Borodia. In that case even if the TVs are being imported from Vernland, the decrease in assemblers in Borodia need not confirm exactly to the increase in the number of assemblers in Vernland
(B): TV features are irrelevant to the argument here.
(C): This is exactly assumption 2 that we mapped out earlier. Correct.
(D): This does not help to reach the conclusion of the stimulus. For instance, it is possible that the local market in Vernland expanded in this period, and in that case the additional TVs would be needed to just satisfy local demand, not import demand for Borodia.
(E): The difference in wage rates is not a factor here.

C is therefore correct.

Hi Ratinarace:

If you want to increase your critical thinking speed, I highly recommend you read "Critical Reasoning - Bible".
For assumption questions, we have 2 types: supporter assumption, and defender assumption. I won't talk in detail here. This question is asking you about supporter assumption.

The question wants you to explain the link: why a drop in the number of television assemblers in Borodia leads to an increase of TV import from Vernland. Clearly, there's a gap between "number of assemblers" and "TV import". The logic is: the number of Borodia TV assemblers decreases --> the number of TVs assembled in Borodia decreases --> Borodia has to import more TV from Vernland.

Name Q = the number of TV assemblers in Borodia
Name T = average hour/day to assemble a TV
Name K = the number of working hours/day for each assembler = constant.
Name P = total TV assembled/day = (K/T) x Q

The stimulus says Q decreased --> P only decrease if T stays the same of just decreases a little bit. Otherwise, if T decreases significantly --> P maybe increase --> so logic would be failed.

For instance:

Q= 100 people; T= 10 hours/TV; K = 10 hours --> the number of TV per a assembler per day = K/T = 10/10 = 1 TV/day --> total TV assembled/day = (K/T)xQ = 1 x 100 = 100 TVs

if Q changes to 50 people, T also decreases to 2.5 hours; K = 10 --> each person will assemble 4 TVs/day --> Total TV = 4 x 50 = 200 TVs --> P increases --> the logic is failed

Answer is (C). I'll try to explain via a hypothetical dialogue.

First identify the conclusion, which in my own words, translates to

"Borodia must have imported more TVs"

A skeptic would then ask, "what makes you come to that conclusion?"

I reply -- "well, because of a few reasons, which are stated in my premises":

1) Borodia sold the same # of TVs for the past 3 years
2) Borodia lost some of its own TV assemblers

1+2 Combined) Borodia sold the same number of TVs while employing fewer assemblers.

1+2+Conclusion) Borodia sold the same number of TVs while employing fewer assemblers. Therefore, they must have imported more TVs

Skeptic, still skeptical, then asks: "well...what if somehow, just SOMEHOW, there was another way Borodia supplied its TVs while employing fewer employees?"

I then reply, "well...I assume there wasn't any other way."

--------------------------------------------------------------------------

Now look at choice (C): The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.


This is telling me the few remaining TV assemblers in Borodia might have become more efficient and produced more TVs per hour.
Tying it back to my hypothetical dialogue:

"Like I said, I assume there is no other way Borodia produced the same # of TVs as last year, including this scenario"

Therefore, answer is (C).

Hi,

The passage in the question is one of those arguments, which, at e-GMAT, we classify as QPA arguments or Quantitative Predictive Arguments. We had written an article on the same some time back. It might help.

I think most people had mistaked hours to make one tv vs number of tv/workder.
I was thinking that hours/tv had not decreased.
This is the keyword.

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia. Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed. However, recent statistics show a droip in the number of television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.

I believe this is clearly (C).

It is true that there was a drop in the number of television assemblers in Borodia.

But the total number of television sets assembled in Borodia does not need to be decreased, if the average number of hours taken to assemble one television set has significantly decreased.

Like this:

Before
- Number of TV assemblers = 10
- Average hour needed per one TV set = 2
- Number of TV sets assembled per day = 120

After
- Number of TV assemblers = 5
- Average hour needed per one TV set = 1
- Number of TV sets assembled per day = 120

Therefore, if the average hour needed to assemble one TV set is decreased, Borodia does not need to import more TV sets.



However, (D) doesn't have to be assumed since there also is a possibility that Vernland reduced the local sales of the TV sets and increased export, or that the demand for TV sets in Vernland decreased.

C it is,

The argument here concludes that as the number of manufacturers in Barodia has decreased, It implies that the imports from Vernland have increased.

The missing piece of information is that in addition to the specified premise, we also need to be told that the remaining manufacturers left in Barodia have not increased their output, if they have, then the conclusion is destroyed.

Option C, provides us with this missing information and therefore serves as the assumption for the argument.

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia. Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed. However, recent statistics show a drop in the number of television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.

Which of the following is an assumption on which the argument depends?
1) Assumption question: Find the core of the passage first
-> Conclusion: The number of TVs Borodia (B) imports from Vernland (V) has increased
-> Key premises: 1) Market demand of TV in B is the same for last 3 years, 2) B's TV are more expensive to make due to wage difference, 3) No. of TV workers in B has reduced

2) Identify the missing link (pre-thinking)
-> B's TV may not be more costly afterall, since increase in wages can be offset by the decrease of # TV assemblers. So cost is unlikely to be the issue. Demand for TVs is however the same. There must be a link between Demand for TV vs the TVs that B makes that necessitates the import of V (i.e. not making enough to meet demand perhaps)


3) Evaluate answer choices

A. The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.
No link to r/s of demand vs import. Alternatively, if V has more TV workers than B, what effect does it make to increasing import? None. Eliminate this.

B. Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
This is a good suggestion to the r/s of demand vs import. However, passage did not include this information so this is OOS. Eliminate this.

C. The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.
This means that B's TV takes longer to make, now that there are lesser workers. This does gives a reason why B has to import from V... because demand outstrips supply within B and have to depend on V instead. Keep this in for now.

D. The number of televisions assembled annually in Vernland has increased significantly during the past three years.
V makes lots of TV now. Will B import them? Who knows (as in does any premises in the passage support this?) No. Eliminate.

E. The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years.
This suggest a change in the cost of making TVs. Both B and V will have narrowing cost differences. Does this have any r/s to demand and import? No - cost is not the topic here.


4) Consolidate
We are left only with 1 candidate through POE. Answer therefore is C. i.e. demand outstrips supply in B, therefore B has to import TVs

OG:
C
What assumption does the argument depend on? The fact that fewer individuals in Borodia are working as TV assemblers is offered as evidence that TV imports from Vernland into Borodia have likely increased. That piece of evidence is relevant only as an indication that the number of TVs being produced within Borodia has decreased. But a drop in the number of TV assemblers does not indicate a drop in the number of TVs being assembled if the number of TVs an average assembler puts together has increased. Thus, the argument must be assuming that the average time it takes an assembler to put together a TV has not significantly decreased.

This choice is the correct one - the author is assuming the time it takes to assembly one TV in Borodian has not changed. For if it had decreased, the whole argument would collaps > there would be less workers producing the same number of TVsets.
The argument doesn't mention that number of TVs decreased.



How is that necessary?
This is a terrible explanation.
How might the argument collapse if C doesn't hold?
Not even an expert comment on this question.
It's awfully bad that no one can explain this answer.

This is regarding your query.
I Analysed the argument first as below.
Attachment:

What can be reason for this Conclusion?

No change in Total sales and
reduction in labor.

Assumptions that must account for the conclusion

    Either skill must have improved i.e., less people are able to assemble more TVs then before 3 yrs
    OR
    the possible reduction in number of TVs due to reduction in assemblers has been supported with imported TVs from Vernland........i.e., conclusion.

So skill related assumption mentioned above must be false............i.e., C.
I hope this helps. :)

This is clear from the word go.
My prethink assumption was MORE TVs were imported from vernland to make the sales remain same.
That's obvious.
How does that relate to C (average hour used to assembly TV...) I.e. how long it takes to assembly a TV in Borod. folks here must think I'm an idiot or something. but believe me I'm struggling to establish the logical link.

Please understand the causual argument hidden here.
Go through this article for the same.
http://www.beatthegmat.com/mba/2011/01/ ... -arguments

If you still have a doubt, best weapon to test the assumption is to negate it.
Try to negate C and then observe the conclusion to collapse.

I tried negating it and the conclusion became more powerful and inevitable.
If it takes them more time to make a telly then they would produce less TV and that's more reason Vernland has to come in so that sales remains same.

hi,
This might be the first time I have come across a OG Q which is not very convincing..
Yes, in the given choices C may be the best ..
So let me take C..
C. The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.
If the Borodian television assembler have started taking lesser time, why should it translate into fewer assembler?
Yes it would mean lesser hour spent on assembling ..

there is a point mentioned above that assembler will not shift to V because hourly wages are lesser as compared to B..
but if B was getting paid $7 per hour and was assembling 1 TV, whereas in V, they were getting $4 and were also assembling 1 tv in one hour..
But B has become more efficient and is now assembling 2 tv..
B is getting paid $3.5 per TV whereas C is getting $4 per TV..
Now yes the assembler in B could move to C
..

How does that relate to C (average hour used to assembly TV...) I.e. how long it takes to assembly a TV in Borod. folks here must think I'm an idiot or something. but believe me I'm struggling to establish the logical link.

Please understand the causual argument hidden here.
Go through this article for the same.

If you still have a doubt, best weapon to test the assumption is to negate it.
Try to negate C and then observe the conclusion to collapse.

Nevernevergiveup
I tried negating it and the conclusion became more powerful and inevitable.
If it takes them more time to make a telly then they would produce less TV and that's more reason Vernland has to come in so that sales remains same.

Am I missing something?


Hi Nez,

I have tried to cover it with my understanding. hope it helps:

This is defender assumption question. Definition (in my own words)

Defender assumption : it means when you conclude something from the information (premises) given, then any information that a critique/lay-man may use to attack/break that conclusion is what you have to defend the conclusion with by saying NO "this is not the case".

So defender assumption is that unstated premise, which the critque may use to attack and you would negate that infor to defend the conclusion.

V=Vernland, B=Borodia

FACT(Premise-1) : Avg hourly wage of V is less than B.

FACT(Premise-2) : Since B dropped Tariffs (charges levied on import of goods) on V's TVs, the #ofTVs sold has not changed.

FACT(premise-3) : Number of assemblers is dropped in B.

Conclusion : Number of TVs imports annualy has increased from V.

Explanation:
I am critique who is good at stats and just by looking at this argument i come and attack this conclusion by saying --->"The technology has increased and has been helping the assemblers so well that they can now assemble a TV in 10 hours which used to take 20 hours 3 years before. So companies in B has dropped the number of assemblers by half who can assemble as many number of TVs as previously assembled. It means that the reason for "the #ofTVs sold has not changed." is the new technology in B not that B has increased import from V.

So this is the information on which argument DEPENDS. Because its not stated as a premise hence it is ASSUMPTION. So if you as the writer tell this/add this in argument then your conclusion is just safe from THIS one particular attack.

Now how to apply this:
Whenever you try to pre-think or paraphrase, just try to think of the key things/points that may attack the conclusion. These points are related to main parameters of argument. In this questions these parameters are hourly wages, number assembler, number of television and average. Of course MOST of the times (at least me) cannot come up with anything on pre-thinking BUT i get know what parameters are there and how are they related.
Now this is very important atleast for someone who is preparing for the GMAT that s/he knows what can impact average, what can imapct number or what can impact hours or what can impact wages when all of these are related.

So when i was doing this question I could not paraphrase anything but the moment i saw hours in the choice i kept it safe and read other choices. took a little long but this was the real attacker.

For defender assumption most of the you will see that a answer choice using negative word is correct. so pick such choices first.WHY? "because you are saying this my conclusion and yeah this is NOT the case if u attack me with it." (general understanding).

Hope it helps :)
