单选题 According to the passage, the relationship between employer and illegal worker is best described as ______.

A、 admirable
B、 amicable
C、 difficult
D、 impersonal

【正确答案】 D

【答案解析】admirable值得赞美的，极好的；amicable友善的，和平的；difficult难相处的；impersonal非个人的。最后一段中说"Most workers do not even know their employers name．"，所以雇主和这些非法移民工人之间的关系是“非个人的”。
