Using standard alphabetical filing rules, which name is filed first: Grace Uy, Grace Uyehara, Grace Uson, Grace Uytengsu?
Correct answer: C. Grace Uson
Indexed surname first, the filing order is USON, Grace → UY, Grace → UYEHARA, Grace → UYTENGSU, Grace. The name filed first is Grace Uson. Comparing the surnames letter by letter, "Us" comes before "Uy", so Uson is first, followed by Uy (nothing before something), Uyehara and Uytengsu.
