To determine which sentence would require a reflexive verb in Spanish, we need to look for actions that someone does to themselves. In Spanish, reflexive verbs are used when the subject and object of the action are the same person.
Out of the sentences provided:
1. "I dry the dishes." - This sentence does not require a reflexive verb because the action is being done to the dishes, not to the speaker.
2. "I dry my hair." - This sentence would require a reflexive verb in Spanish because the action of drying is done to oneself (the speaker's hair).
3. "I dry the paint." - This sentence does not require a reflexive verb as the action is done to the paint, not to the speaker.
4. "I dry my clothes." - This sentence would also require a reflexive verb in Spanish because the action of drying is done to oneself (the speaker's clothes).
Therefore, sentences 2 ("I dry my hair.") and 4 ("I dry my clothes.") would require reflexive verbs in Spanish.
