Railroads rely increasingly on automation. Since fewer railroad workers are needed, operating costs have been reduced. This means that we can expect the volume of freight shipped by rail to grow. The chief competitor of railway shipping is shipping by truck, and no reduction in operating costs is predicted for the trucking industry.

Summarize Argument
The author concludes that we can expect the volume of freight shipped by rail to increase. This is because railroads have had reduced operating costs, whereas the main competitor to railway shipping (trucking) is not predicted to have reduced operating costs.

Identify Conclusion
The conclusion is the author’s prediction for what will happen to the volume of rail freight shipping: “[W]e can expect the volume of freight shipped by rail to grow.”

A
The volume of freight shipped by rail can be expected to increase.
This is a restatement of the conclusion.
B
Increasing reliance on automation means that fewer railroad workers are needed.
This is part of the support. Because fewer railroad workers are needed, the railroad industry has reduced operating costs. The author uses this support a prediction about an increase in the volume of rail freight.
C
No reduction in operating costs is predicted for the trucking industry.
This is a premise. The author uses the lack of reduced operating costs in a competitor industry to support a prediction about the increase in rail freight.
D
Operating costs for railroads have been reduced as a result of increased reliance on automation.
This is part of the support. Because of the reduced operating costs, the author predicts an increase in rail freight.
E
The chief competitor of railway shipping is shipping by truck.
This is a premise. The author points out that rail’s chief competitor isn’t predicted to have reduced operating costs to support the prediction that rail freight volume will increase.
