Industrialists from the country Distopia were accused of promoting the Distopian intervention in the Arcadian civil war merely to insure that the industrialists’ facilities in Arcadia made substantial profits during the war. Yet this cannot be the motive since, as the Distopians foresaw, Distopia’s federal expenses for the intervention were eight billion dollars, whereas, during the war, profits from the Distopian industrialists’ facilities in Arcadia totaled only four billion dollars.
Which of the following, if true, exposes a serious flaw in the argument made in the second sentence above?
(A) During the Arcadian war, many Distopian industrialists with facilities located in Arcadia experienced a significant rise in productivity in their facilities located in Distopia.
(B) The largest proportion of Distopia’s federal expenses is borne by those who receive no significant industrial profits.
(C) Most Distopian industrialists’ facilities located in Arcadia are expected to maintain the level of profits they achieved during the war.
(D) Distopian industrialists’ facilities in Arcadia made substantial profits before the events that triggered the civil war.
(E) Many Distopians expressed concern over the suffering that Arcadians underwent during the civil war.

Yes it should be B.

The question asks as to why industrialists from Distopia promoted intervention inspite of expenditures being greater than the profits to the country. Choice B helps explain this.
As the largest proportion of Distopia's federal expenses is borne by those who receive no significant industrial profits, Industrialists were eager to post higher profits and obviously explored all options.
Also If a large proprotion of the expenses are not borned by these industrialists, then it's right to say they profited from the war.

'B' it is.

B makes sense since this will provide a motive for the indutrialists to call for the intervention.

Straight B
