Correct Ans is A:
Here is why I believe
(Mind you this is an Except Q, which means all other ans will strengthen author pov except 1)
A. Although non-Ossamian countries have a military and trade presence in Ossamia, their oil sales last year in the region were not significantly above normal levels. -
this is not strengthening the author pov that trade presence will lead to increase in salesB. Mines accessing Kokua's rich natural resources were put into operation for the first time last year. - this will result in increase oil sales
C. Each of the Ossamian countries currently have few restrictions in place on the business that can be done with its neighboring countries. - few restriction means more business, more sales
D. One of Energy Corp's primary competitors had a tanker accident early last year that caused environmental damage in Ossamia and damaged the company's standing in the area. - competitor had an accident which provided an edge to the Energy Corp sales
E. One of Ossamia's neighbors, a developing nation, has a growing population with a reasonable amount of disposable wealth. - growing population with disposable wealth means more chance of trade
Hope this helps!
Thanks!!
