Yanıt Açıklaması: 'Have' and 'have to' don't match grammatically (according to conjugation rules, 'she' matches with 'has'). The verb 'wear' requires the preposition 'to' before it, so 'has' is not the correct answer. And since wearing uniform in schools is an general obligation, 'want to' wouldn't be a conveniant answer. The correct answer should be 'has to'.
