Critical Reasoning

Ques: From a letter to the commercial editor of a newspaper: Your article of January 9 drew attention to the large deficit in Playland's balance of payments that has worsened over the past three years. Yet, you favor the recent trade treaty signed between Playland and Workland. That treaty results in a lowering of our import duties that will flood us with Workland's goods. This will only exacerbate our balance of trade. How can you be in favor of the treaty?

Which of the following considerations would weaken the letter writer's argument?

A) import diversion versus import creation
B) prices paid by importers versus prices paid by consumers
C) economic goals versus political goals
D) duties levied increase government revenue
E) free trade versus protectionism

Can anybody tell me the correct answer? Please explain.

Thanks
