<span>Stem changing verbs have spelling changes in all forms of present tense EXCEPT nosotros(as) & vosotros(as). Stem of verbs are the part of the infinitive that's left after dropping endings such as -ar, -er, or -ir. Pedir translated is "to ask or order". The way you'd put that in present is Yo - Pido. Tu - Pides. El, Ella, Ust. - Pide. Nosotros - Pedimos. Vosotros - Pedis. Ellos, Ellas, Uds. - Piden. Servir is the same way just replace the -ir with the correct change.</span>
I think the answer would be "Pasos"
Note:
I will also add the list for correct version for the ones that aren't
Answers:
1st. None of them, you should check if there's a typo somewhere
2) Yo hago
- tu haces
- nosotros hacemos (nosotros hagamos is actually a correct conjuagation but i believe that it is too advanced at the moment seeing what this is)
- ellas hacen
3) Yo prefiero
- tú prefieres
- nosotros preferimos
- él prefiere
4) Tú tienes
- ella tiene
- ellas tienen
- yo tengo
5) Él camina
- tú caminas
- yo camino
- nosotros caminamos (this one is also correct but same reason as before)
