Only E weakens this economists argument that country B will sell more to European countries to make up for the loss of sales to US. E says that cost of transportation will make the salmon from B more expensive than the salmon from other countries. Imagine this : in ur local grocery store, salmon with "made in B" will be more expensive than the similar salmon (size, taste etc) with a label "Made in Timbuktu". Hence ppl will buy the one from Timbuktu....
As a result Eu countries will stop/reduce buying salmon from B. ..
hence a weaker to Economist's argument.

HT Helps.

IMO:E

E states a reason why European country may stop importing salmon from country B.

e for me too...wats the OA??

OA : E

IMO D

In my opinion D is the most logical one.
