CR: The average hourly wage of television assemblers in Vern

[tim]

It definitely takes practice. Good luck down the home stretch.

Hi Ron,

I understood why C is correct answer but want to know why D is wrong?
How can I eliminate D?

Thanks,

Here's the easy answer: Once you know that C is correct, ALL the other answers are wrong. End of story. No problem on the GMAT has two correct answers.

What makes you think D is relevant?

The basic answer to your question is that D is irrelevant. Without knowing what connection you saw——or, more properly, what connection you thought you saw——it's not possible to answer your question in more detail.

Hi ron,
As to D, I feel like if the production of V does not increase, and B's production decreased.

How can you make the conclusion that "the number of televisions Borodia imports annually from Vernland has increased."?

...
How can you make the conclusion that "the number of televisions Borodia imports annually from Vernland has increased."?

the green part makes me think you're trying to use the negation method. are you trying to use the negation method?
if so, then you have the goal backward. when you negate something that's supposed to be an assumption, you want to destroy the argument. not prove it!

[RonPurewal]

oh, and, this...

, and B's production decreased.

where are you getting this?
there's no evidence for this statement anywhere in the passage.

the passage states that the number of people assembling televisions in B has gone down, but that's definitely not the same thing as what you wrote here.
in fact, THE ENTIRE PURPOSE OF THIS PROBLEM is to test whether you can realize that "fewer people producing tv's" is different from "fewer tv's being produced".

... and, finally, don't forget that choice D is one of the wrong answers.
so, if you're asking "why doesn't this work?" ... well, it's not supposed to work. it's an incorrect answer choice.

Pre-thinking:
The time taken to assemble television set has not decreased either it is of the same value or increased, but not decreased for sure.

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.
This doesn't guarantee the conclusion as the number would have increased because of two reasons: Sales have increased in Vernland or the sale has remained constant, but the time to assemble a television has increased.

B. Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
Completely OFS, not even a contender for the right answer 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 in frequency with our thinking.

D. The number of televisions assembled annually in Vernland has increased significantly during the past three years.
This is quite similar to Option A.
This doesn't guarantee the conclusion as the number would have increased because of two reasons:
Sales have increased in Vernland, or the sale has remained constant, but the time to assemble a television has increased. AlternativelyVernalnd is now Importing to Borodia

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.
OFS.

Although we can easily eliminate D, but we can test negation.


Conclusion: Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed.Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.

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.

Negated Sentence: The average number of hours it takes a Borodian television assembler to assemble a television has decreased significantly during the past three years.
This now means that average hours have decreased now Borodian should make more television and hence there will be surplus television than demand. This kills the possibility of import. C stands in competition for the correct answer.

D. The number of televisions assembled annually in Vernland has increased significantly during the past three years.
Negated Sentence: The number of televisions assembled annually in Vernland has decreased significantly during the past three years.


I always get confused in negation. I negated D and the negated version also seems to be killing the conclusion that Vernland is importing from Borodia.

When I apply negation D also seems to be a correct option.

[RonPurewal]

for choice D, i don't know why you are thinking about importing things INTO vernland... go back and read the question again.

in any case, this is an OG problem, so, it shouldn't even be on this forum anyway. this thread is now locked.
