I have a question about the following CR weaken problem and would appreciate human reasoning rather than AI-generated answers.
Argument:
Last year was the first year that private companies, rather than the government, operated the passenger rail service in the nation of Gordor. The number of passenger complaints about trains running late was up by 27 percent over the year before. Clearly, therefore, privatizing Gordor’s railroads, far from bringing about any improvement in the punctuality of trains, has actually caused a deterioration of that aspect of passenger rail service.
Question: Which of the following, if true about Gordor, most seriously weakens the argument?
A. Passengers believe that the private companies now operating the passenger rail service are more likely than the government was to respond with corrective action to complaints received.
B. After the privatization of passenger rail service, the companies operating the trains discontinued a number of train services that had very low passenger volumes.
The answer key says B, but I am struggling to see why B is a stronger weaken answer than A.
My reasoning:
The argument relies entirely on the following assumption:
More complaints about late trains → More late trains → Worse punctuality.
Choice A seems to directly attack this assumption.
If passengers believe private companies are more responsive to complaints than the government was, then complaints could increase even if train punctuality remained unchanged. In other words:
* Same punctuality
* Greater willingness to complain
* More complaints
This appears to provide a very direct alternative explanation for the observed 27% increase in complaints.
By contrast, B seems to require several additional assumptions:
* Low-volume routes were discontinued.
* Passengers shifted onto remaining routes rather than simply not traveling.
* This change in passenger distribution increased the absolute number of complaints.
* Therefore complaints increased even without a deterioration in punctuality.
I can see how B might weaken, but it feels much more inferential than A.
What am I missing?
Please use your own reasoning rather than AI tools. I am particularly interested in how GMAT would justify B being stronger than A.
