Police Chief of Megalopolis: Five years ago, the city's police department introduced innovative policing strategies. Since then, the crime rate in Megalopolis has declined significantly. Our new strategies should be credited with bringing about the decline. It has been objected that there have been significant declines during the past five years in crime rates throughout the nation and that therefore Megalopolis' crime rate would probably have declined even without the new policing strategies. Once we had introduced the new strategies, however, they were soon adopted by police departments in cities throughout the nation, and it was only then that crime rates in those cities began to decline.
In the police chief's argument, the two boldface portions play which of the following roles?
A. The first presents a phenomenon whose interpretation is at issue in the argument; the second presents a claim that the police chief denies.
B. The first presents a phenomenon whose interpretation is at issue in the argument; the second presents evidence that has been used to undermine the police chief's interpretation of that phenomenon.
C. The first presents evidence, the accuracy of which the police chief questions; the second supplies a reason for the police chief to question the accuracy of that evidence.
D. The first presents evidence that has been used to support the hypothesis that has been proposed as an alternative to the police chief's hypothesis; the second provides evidence to weaken that support.
E. The first and the second each provide evidence that has been offered to support an objection to the police chief's view.

Police Chief of Megalopolis: Five years ago, the city's police department introduced innovative policing strategies. Since then, the crime rate in Megalopolis has declined significantly. Our new strategies should be credited with bringing about the decline. It has been objected that there have been significant declines during the past five years in crime rates throughout the nation and that therefore Megalopolis' crime rate would probably have declined even without the new policing strategies. Once we had introduced the new strategies, however, they were soon adopted by police departments in cities throughout the nation, and it was only then that crime rates in those cities began to decline.
Reading the passage, we see that the main conclusion is the following:
Our new strategies should be credited with bringing about the decline.
Along with that conclusoin the police chief presents an objection to the conclusion and evidence in favor of the conclusion.
In the police chief's argument, the two boldface portions play which of the following roles?
The correct answer will correctly describe the roles of the two boldface portions.
A. The first presents a phenomenon whose interpretation is at issue in the argument; the second presents a claim that the police chief denies.
The easiest way to eliminate this choice is to see that the second boldface portion does not present a claim that the police chief "denies." Rather, the second boldface portion is evidence that the police chief uses to counter the objection that "there have been significant declines during the past five years in crime rates throughout the nation and that therefore Megalopolis' crime rate would probably have declined even without the new policing strategies." In other words, the police chief believes what the second boldface portion says and uses it to support the police chief's conclusion.
We could say that this first part of this choice is correct because the fact that "there have been significant declines during the past five years in crime rates throughout the nation" could be considered a phenomenon whose interpretataion is at issue. After all, apparently, some people are objecting that that phenomenon indicates that the police chief's conclusion is not valid while the police chief is saying that that phenomenon is the result of the city's police department having "introduced new strategies."
So, we have to be careful not to choose this choice just because the first part could be correct.
Eliminate.
B. The first presents a phenomenon whose interpretation is at issue in the argument; the second presents evidence that has been used to undermine the police chief's interpretation of that phenomenon.
This choice starts off like choice (A). So, the first part could be considered correct for the reason we discussed when considering choice (A): The fact that "there have been significant declines during the past five years in crime rates throughout the nation" could be considered a phenomenon whose interpretataion is at issue. After all, apparently, some people are objecting that that phenomenon indicates that the police chief's conclusion is not valid while the police chief is saying that that phenomenon is the result of the city's police department having "introduced new strategies."
At the same time, the second part of this choice is incorrect because the second boldface has not "been used to undermine the police chief's interpretation of that phenomenon." Rather, the police chief uses the second boldface to support the police chief's interpretation of the phenomenon, which is that the phenomenon is the result of the city's police department having "introduced new strategies."
Eliminate.
C. The first presents evidence, the accuracy of which the police chief questions; the second supplies a reason for the police chief to question the accuracy of that evidence.
This choice is tricky because, while neither the first nor the second part of it is correct, they both have a vibe of being correct.
In the case of the first boldface portion, the police chief does not question its accuracy. At the same time, we could get the impression that the first part of this choice is correct because the police chief does argue against how some people have interpreted the fact presented by the first boldface portion.
In the case of the second boldface portion, it does not supply a reason for the police chief "question the accuracy" of the first. At the same time, we could get the impression that the second part of this choice is correct because the police chief does use the second boldface portoin to challenge an interpretation of the first boldface portion. So, the second part of this choice is somewhat similar to the role of the second boldface portion.
Eliminate.
D. The first presents evidence that has been used to support the hypothesis that has been proposed as an alternative to the police chief's hypothesis; the second provides evidence to weaken that support.
The first part of this choice is correct because the fact that "there have been significant declines during the past five years in crime rates throughout the nation" has been used as evidence to support the hypothesis that, contrary to the police chief's conclusion, "Megalopolis' crime rate would probably have declined even without the new policing strategies."
The second part of this choice is correct because the police chief uses the fact that the city's police department's new policing strategties "were soon adopted by police departments in cities throughout the nation" as evidence to support the police chief's conclusion that the new strategies "should be credited with bringing about the decline" and to weaken the support for the objection to that conclusion.
Keep.
E. The first and the second each provide evidence that has been offered to support an objection to the police chief's view.
This choice correcty describes the role of the first boldface portion. After all, the first boldface portion has been used as evidence to support the objection that "Megalopolis' crime rate would probably have declined even without the new policing strategies."
However, this choice does not correctly describe the role of the second boldface portion. After all, the second boldface portion is not offered to support an objection to the police chief's view but rather is offered by the police chief as support for the police chief's view.
Eliminate.
