city's transportation network

by siddhu161 » Sat Jan 11, 2014 4:37 am
The city government should invest surplus funds in improving the city's transportation network. Most of the network was put in place at a time when the city was much smaller in both area and population. The subway system is outdated and understaffed. The buses rarely run on schedule and their routes are inconvenient. If the city does not make changes soon to the network, it will see many of its prized industries relocate to more convenient cities and, as a result, the city's financial health will be jeopardized.

In the argument above, the two portions in boldface play which of the following roles?

a. The first provides context for a current state of affairs; the second is a prediction based on that state of affairs.
b. The first is a statement of fact in opposition to the author's conclusion; the second supports that conclusion.
c. The first lays the background for the author's principal contention; the second is that contention.
d. The first is information the author suggests has been overlooked in the situation at hand; the second describes that situation.
e. The first provides data to support the author's conclusion; the second verifies the validity of those data.

Conclusion: The city government should invest surplus funds in improving the city's transportation network.

BF 1: Most of the network was put in place at a time when the city was much smaller in both area and population
This is background information that serves to SUPPORT the conclusion:
WHY does the transportation network need to be improved?
Because most of the network was put in place at a time when the city was much smaller in both area and population.

BF 2: If the city does not make changes soon to the network, it will see many of its prized industries relocate to more convenient cities and, as a result, the city's financial health will be jeopardized
This is a prediction that serves to SUPPORT the conclusion:
WHY does the transportation network need to be improved?
Because if the city does not make changes soon to the network, it will see many of its prized industries relocate to more convenient cities.

MATCH the answer choices back to the BFs.
Eliminate any answer choice that doesn't match.

A:
The first provides context for a current state of affairs.
YES:
Background information = context.
The second is a prediction based on that state of affairs.
YES:
If changes are not made, the city will suffer.
Hold onto A.

B:
The first is a statement of fact in opposition to the author's conclusion.
NO:
The first BF serves to SUPPORT the conclusion.
Eliminate B.

C:
The second is that contention.
NO:
The second BF serves as a PREMISE, not as a conclusion.
Eliminate C.

D:
The first is information the author suggests has been overlooked in the situation at hand; the second describes that situation.
NO:
The second BF makes a PREDICTION; it does not describe the current situation.
Eliminate D.

E:
The first provides data to support the author's conclusion.
NOT REALLY:
The first BF gives general background information; it does not supply any actual numerical data.
The second verifies the validity of those data.
NO:
The second BF does not serve to confirm that the city used to be much smaller.
Eliminate E.

The correct answer is A.

Thanks Mitch. Just a small query. Is contention and conclusion one and the same thing?

A contention is an opinion or assertion put forth in an argument.
Here, the author's principal contention = the author's conclusion.
