Premise: Companies are emphasising helping spouses of expatriate employees adjust to foreign environments.
Conclusion/Argument: Premature returns reduced by 67 percent.
Pre-thinking: Spouses couldn't adjust to the foreign environments due to which the employees had to return
(A) Spousal and marital difficulties were formerly responsible for many premature returns from foreign assignments.
This connects spousal issues directly to premature returns, and also aligns well with our pre-thinking. Keep
(B) When an employee is placed in a foreign assignment for a year or less, his or her family sees the assignment as an adventure.
Irrelevant, if anything this goes against the premise telling us that the family adjusts well to the foreign environment. Eliminate
(C) Expatriate employees work long hours and travel a great deal, and their children make new friends at school, but spouses often have no friends and no work to support them while they're abroad.
This gives us a reason why spouses might have difficulties but can't be directly tied to premature returns. It's not a required assumption, spouses could have no friends or work and still adjust well to the foreign environment. Eliminate
(D) The majority of international assignments today last for less than a year, but ten years ago, 70 percent of them lasted much longer than one year.
Comparing assignment lengths over time doesn't tell us anything. Eliminate
(E) Many companies now offer expatriate spouses language training, career guidance, and assistance in finding homes and schools.
This restates the conclusion that companies provide spousal support but doesn't establish why this lack of support was actually causing premature returns. Eliminate
The correct answer is (A)
