Superconductor development will enable energy to be transported farther with less energy lost in transit. This will probably improve industrial productivity, for a similar improvement resulted when oil and natural gas replaced coal as the primary fossil fuels used in North America. Shipping costs, a function of the distance fossil fuels are shipped and the losses of material in transit, decreased for factory owners at that time.

The claim that superconductor development will probably improve industrial productivity plays which one of the following roles in the argument?

(A) It is a conclusion for which the claim that shipping costs for fossil fuels are partly a function of the losses of material in transit is offered as partial support.

(B) It is a generalization for which the claim that superconductor development will enable energy to be transported farther with less energy lost in transit is offered as an illustration.

(C) It is an assumption supporting the conclusion that superconductor development will enable energy to be transported farther with less energy lost in transit.

(D) It is a premise offered to support the claim that oil and natural gas have replaced coal as the primary fossil fuels used in North America.

(E) It is cited as evidence that shipping costs are a function of the distances fossil fuels are shipped and the losses of material in transit.

Try to understand what the sentence "SD will probably improve industrial productivity" does in the passage.
It is a position that is supported by a fact - SD can transport energy for greater distances w/o wastage.

And then a situation is presented that the Author thinks is analogous.
Oil and NG replaced Coal in NA. Shipping costs reduced as a result.

Hence, "SD will probably improve industrial productivity" is the Main Conclusion here.

A. This is the only choice that rightly shows the relation of the conclusion with another part of the passage (Here, the supporting claim - Shipping Costs are a function of losses of material and Distances) among all the choices.
