The Nordlingen WE luxury sports car uses a special imported rosewood

lexis and ankita nail it above - it's that addition of the word "major" that dooms (B). We don't need rosewood to be a MAJOR factor in the price...as long as it's a factor at all, then the increase in rosewood cost can still be reflected in the overall price.

Two big lessons here:

1) Precision in wording matters! Especially in the cases of the conclusions of arguments, the major premise leading to a conclusion, or assumption answer choices, if an adjective (like "major") or modifier is added, it's usually a huge deal.

Here without "major" (B) would be correct. But like lexis and ankita mentioned, we don't need rosewood to be a major cost contributor, and assumptions are necessary premises.

2) Whenever a conclusion of a strengthen/weaken/assumption question, or the objective of a plan/strategy question, mentions an increase or decrease, even a marginal increase or decrease will satisfy that! Unless that conclusion/objective specifically calls out a threshold (a major reduction, a 50% increase), then you just need to get some, even small, level of increase/decrease. But the testmakers know that your mind wants to go to a big increase/decrease, so there will be trap answers that tempt you with "but it won't be that big of an increase/decrease." Make sure you stay tight to the actual conclusion, which in this case is just "an increase."

"D". For the price to increase, wood has to be used and then its price has to increase. D tells us that author assumed that even in new models this wood be used.

The conclusion here is the last statement:
"Purchasers of the new models of the Nordlingen WE can expect to see that increase reflected in an increase in Nordlingen's ticket price".

It cannot be 'C' becos the conclusion is concerned about the increase in price & not about the usage of imported rosewood, so it is 'D'

Between B and D, I go with D. Argument assumes that this "extremely rare commodity" will still be used in the manufacturing of the cars.

I think D .
A - That is a fact
B - Well this may be as assumption
C - Out of context
D - Assumtion stronger than B
E - Out of context

Oh, I got some mistakes. After reread the passage, I concur that D is the best answer.

Let me crack B,
The conclusion must base on assumption that rosewood will still used in next generation of WE models.
B reveals flaw when we cast doubt on the MAJOR FACTOR, wonder what will happen if it is NOT major factor, but rather second or third factor? Price of WE still increases!

Therefore, D is BEST :D

First read and A, C and E are out.

B/w B & D apply negation tech. i.e. after negating the assumption should weaken the argument.
negating D demolishes the argument ... so go with D

always use negation in Assumption Q when stuck (only after eliminating a few options) !

Hello,

I am also torn regarding why B is not the correct answer. Could someone please provide insight about why B is out? It seems like a valid argument to me.

Thank you!
