This error has cropped up again, with one editor describing the girls as "adoptive" sisters. Even if they are actual biological sisters rather than just sisters-by-way-of-adoption (we don't know either way), none of them actually carried out the adoption, so their relationship with one another is "adopted", not "adoptive".
