اية الحل الصحيح

She ............ have to buy a new dress because her mother bought her one.
)don't -doesn't -didn't -needn't

[أبو علاء الدين]

the right answer is " doesn't" because of the sequence of the tenses here. If the sentence was
she ..........have to buy a dress because her mother had bought her one. the right answer would be : didn't>

didn't

This is past simple. So, if we add "ten years ago" to the sentence, for example, it will be more obvious.
So, the present simple here wouldn't be suitable. Instead, the present perfect would be more suitable after .because" just to choose "doesn't"
