why is it not children? as in the woman chose the good children over the misbehaving ones. which children did she choose, the good ones or the needy ones? We are setting up a teaching farm for challenged teens. most of them would be classified as "troubled" or bad. I would choose them, The children not singular. If you were talking about a mother at a playground. it would be different. of course it would be which child did she choose? hers! or the one. this reminds me of the difference or similarity between dere & du.
