What action does Peter take when he dances?

When considering Peter's actions while dancing, the correct answer describes a common social mishap during dance. Stepping on someone's feet can happen, especially if one is less experienced or not paying attention to the movements of their partner.

In dancing, stepping on someone's feet suggests a lack of coordination or awareness of space, which can often result from trying to follow the beat or the lead of a partner. This is a recognizable scenario many people can relate to, making it a plausible and vivid option.

The other choices suggest different actions that are generally less likely to occur in social dancing. Twisting, shuffling, or turning someone else's feet may imply a more intentional engagement with their movement, which doesn't align with the idea of an accidental misstep typical when a dancer inadvertently steps on their partner's feet. These actions might not convey the same level of social interaction or common dance errors as stepping on feet does.
