In the analyst's claim, they make a clear unstated link between the lowering of the cost of electric cars, and the increase in demand that will have for the sales and pre-order of electric cars in urban areas. However if price is not a factor for buyers when choosing cars, then this reduction will have little to no change for sales. We must find the answer choice that most fits this assumption.
Let us go through the answer choices
(A) Urban infrastructure, such as charging stations, will become more widely available in city areas this year.
It is not stated that accessibility to charging stations was ever a factor in the sales of electric cars.
(B) The performance of electric cars, in terms of speed and comfort, is on par with that of gasoline-powered cars.
Yet again, this is a premise that was not stated. Nothing was said regarding the relationship between electric cars and gasoline-powered cars. We do not know why people by electric cars, perhaps it has nothing to do with speed or comfort.
(C) City dwellers are primarily motivated by cost savings when choosing a vehicle.
The analyst clearly makes a link between the affordability of the cars and an increase in their sales. Therefore the assumption is that consumers must be primarily motivated by cost savings when choosing a vehicle. If they are motivated by other factors and not by cost savings at all, then changes in price will have little to no effect on sales.
(D) The cost of gasoline will remain stable throughout the year.
Again, we do not know why electric cars were chosen over gasoline-powered cars. This statement is not strong enough for an assumption. What if gasoline prices are not stable and go up, that will only benefit electric cars. Maybe they go down, but people still choose electric cars. We have no link between cost of gasoline and demand for electric cars.
(E) The production of electric cars will be sufficient to meet the increased consumer demand this year.
This answer choice is more tempting however the key is that both sales
AND pre-orders will significantly increase. Perhaps people will pre-order the car this year, and wait until next year for them to be delivered. It is not mentioned in the text that cars must be promptly delivered.
So the answer is C
Bunuel
Analyst Claim: The sales and pre-orders of electric cars in urban areas will significantly increase this year. The primary reason for this increase is that ongoing improvements in battery technology have substantially lowered the cost of electric cars, making them more affordable for city dwellers.
Which of the following is an assumption made in drawing the conclusion above?
(A) Urban infrastructure, such as charging stations, will become more widely available in city areas this year.
(B) The performance of electric cars, in terms of speed and comfort, is on par with that of gasoline-powered cars.
(C) City dwellers are primarily motivated by cost savings when choosing a vehicle.
(D) The cost of gasoline will remain stable throughout the year.
(E) The production of electric cars will be sufficient to meet the increased consumer demand this year.
