In an effort to reduce traffic congestion in downtown Whitmore during the morning rush-hour, the city's transportation commission constructed a new highway connecting Whitmore directly with its northern suburbs. But since the completion of the highway, traffic congestion in downtown Whitmore has actually increased during the morning rush-hour.

Which of the following, if true, would best explain the increase in traffic congestion?

A) More commuters to downtown Whitmore come from the southern suburbs than from the northern suburbs.
B) Because the new highway gives downtown Whitmore residents easy access to the northern suburbs, several new businesses have opened adjacent to the highway in the northern suburbs.
C) Many who live and work in the northern suburbs have begun to use the highway as a way to access downtown Whitmore's nightlife.
D) The convenience of the new highway has encouraged many commuters from the northern suburbs to drive to work in downtown Whitmore rather than take public transportation.
E) The majority of people who work in downtown Whitmore also live in downtown Whitmore.

VERITAS PREP OFFICIAL SOLUTION:

In this "Explain the Paradox" problem, it is critical to identify the specifics of the "surprising fact." What's surprising here is that traffic congestion in downtown Whitmore has actually increased during the morning rush-hour despite the construction of a new highway that might have been thought to decrease it. Answer choice D is the only choice that explains why it may have increased (as opposed to staying the same or not decreasing as much as hoped) - it's that the highway has encouraged more people to drive, so there are more vehicles on the road to add to potential congestion.

Note that the incorrect answer choices might seem relevant, but all are off because they miss the specificity in language of the "surprising fact." Choice A, for example, suggests that a better plan would have been to build a highway in the opposite direction because more congestion comes from the south than from the north. But that doesn't mean that the existing highway wouldn't have at least reduced congestion somewhat, and the surprise is that congestion increased, not that it did't decrease as much as one would have hoped.

Choice B is also a bit off due to specificity in language: the increase in congestion is in downtown Whitmore, but B talks about why there might be more congestion in the suburbs.

Choice C talks about nightlife, reasons that there might be more traffic coming into Whitmore in the evenings. But, again, the "surprising fact" is specific to the morning rush-hour, so C misses the scope.

And choice E is similar to A, showing why traffic may not have decreased much - most people live in the city and wouldn't need to use the new highway - but misses the scope of the paradox, that traffic actually increased. The correct answer is D.

premise: to reduce traffic congestion in downtown Whitmore during the morning rush-hour, the city's transportation commission constructed a new highway connecting Whitmore directly with its northern suburbs.
conclusion: traffic conditions are not better even worsen.
What to do? : what would best explain the increase in traffic congestion?
pre-thinking: some alternate cause, new route is not good or lengthy.

A) More commuters to downtown Whitmore come from the southern suburbs than from the northern suburbs.--- it is still not explaining why using this route.
B) Because the new highway gives downtown Whitmore residents easy access to the northern suburbs, several new businesses have opened adjacent to the highway in the northern suburbs. --- new businesses are not in our scope.
C) Many who live and work in the northern suburbs have begun to use the highway as a way to access downtown Whitmore's nightlife. ---- this seems a problem present from start. new suburbs has nothing to do with it. moreover it is not able to explain th increased traffic.
D) The convenience of the new highway has encouraged many commuters from the northern suburbs to drive to work in downtown Whitmore rather than take public transportation. --- people stopped using public transportation and driving to work that to downtown whitmore. seems like the root of whole thing. an alternate cause.
E) The majority of people who work in downtown Whitmore also live in downtown Whitmore. --- explain the traffic pls.

B, C, and E are Irrelevant.

A and D are close. I don't find anything wrong in A also, but (D) is better than A considering scope of the passsgae.

(D)
