Question

before the war, peoples of japanese ancestry were a small but valuable element in our population. their record of law - abiding, industrious citizenship was surpassed by no other group. their contributions to the arts, agriculture, and science were indisputable evidence that the majority of them believed in america and were growing with america.... among the casualties of war has been america’s japanese minority.... it is my prayer that other americans will fully realize that to condone the whittling away of the rights of any one minority group is to list a detail that could be used as evidence to support an argument against internment.

Explanation:

To support an argument against internment, we can use the detail from the text about the Japanese - ancestry population's record of law - abiding and industrious citizenship. The text states "Their record of law - abiding, industrious citizenship was surpassed by no other group" and also their "contributions to the arts, agriculture, and science were indisputable evidence that the majority of them believed in America and were growing with America". Either of these details can be used. For example, the fact that their record of law - abiding, industrious citizenship was surpassed by no other group shows that they were a valuable and law - abiding part of the population, so internment (which would be a violation of their rights) is unjust.

Answer:

Their record of law - abiding, industrious citizenship was surpassed by no other group (or Their contributions to the arts, agriculture, and science were indisputable evidence that the majority of them believed in America and were growing with America)
