CR - Logical gap assumption

by karthikpandian19 » Tue Jul 10, 2012 12:14 am
The CEO of a company that sells fuel-efficient automobiles recently won a lawsuit against a car dealership that sold fuel-efficient automobile models which were found to be imitations of his company's patented technology. Subsequently, all car dealerships have been prohibited from selling similar imitations. Thus, many car dealerships will now have to pay more for their inventories, because the patented automobile line costs significantly more than the prohibited imitations.

The conclusion above is based on which of the following assumptions?


(A) Most people are unable to distinguish the patented model from imitations.

(B) The patented automobiles are much more desirable than are the imitations.

(C) The patented fuel-efficient automobile is not available to some car dealerships.

(D) The lawsuit did not prohibit the sale of imitations of patented fuel-efficient small trucks.

(E) Car dealerships will continue to sell fuel-efficient automobiles.

The correct answer is E.
In order to solve this type of a question a good method is to try to contradict every answer choice and check whether it influences the argument.

OA is E



We're told that a car dealership was successfully sued by because it sold cars that violated a patent. As a result, all dealerships are now forbidden to sell cars that use the imitated technology that got the car dealership into trouble.

Based on this evidence, the conclusion of this passage states that car dealerships will have to pay more for their inventory because the patented line is more expensive.

We are asked to find an assumption that this conclusion relies upon. That is, we must determine which answer choice is a necessary premise; if the assumption is not true, the evidence will not lead to the conclusion.

Choice E is correct. This choice states that car dealerships will continue to sell any fuel-efficient automobiles. The conclusion of this argument relies on this premise, because it states that car dealerships will pay more specifically for the patented fuel-efficient automobiles. If car dealerships were to give up on fuel-efficient automobiles altogether (which negates this assumption), their inventory prices would not necessarily increase and the conclusion may not be true.

Choice A addresses consumers' inability to distinguish between the patented model and imitations. This is irrelevant to the conclusion of the argument, because imitation models are no longer available to consumers through car dealerships.

Choice B discusses the relative desirability of the two models. This is irrelevant, both because imitations are now prohibited, and because there is no clear relationship between the desirability of an automobile and the prices that the dealerships pay for their inventories.

Choice C is out of the scope of the passage. Limited availability of fuel-efficient automobiles wouldn't necessarily drive up the overall cost of the dealers' inventory (what about dealers who are unable to buy fuel-efficient automobiles at all?).

Answer choice D refers to "patented fuel-efficient small trucks," which is a different group than the set of patented fuel-efficient automobiles mentioned in the argument. One does not need to rely on this fact about small trucks being true to draw the conclusion made in the argument.

Choice E is correct.

This is an easy one.

Since the fuel efficient car cells are now patented, automobile manufacturers who were earlier selling cheap imitations will now need to pay more and hence sell for more. So the assumption here is that the dealers will still continue to sell these fuel efficient cars.

This choice is explicitly stated in E.

All other choices are either out of scope or do not effect the conslusion.
