May I ask what is the sentence? I could help you
Answer:
I think the answer is "un cepillo de dientes"
That means a tooth brush. Hope this helped :)
Infinitivo: Dormir, hacer
Que yo: Arregle
Que tu: Duermas
Que nosotros Arreglemos, hagamos
Que ellas: Hagan
It’s *lógico* because in the supermarket you buy all those things so it’s correct
