In a theater company, there are two directors, Carlos and Maria, who are overseeing different productions. Carlos is directing a play featuring actors named Diego and Isabella, while Maria is directing a different play that includes Isabella and another actor named Alejandro. Each play uses different set designers, with Pablo assigned to the play that Diego is in, and Lucia is designing the set for Alejandro's play. Explain the relationships between the directors and actors and the set designers and plays. Also, describe Carlos's involvement in the play that has Alejandro as an actor.

Provide a short response.
Carlos is a director overseeing the play that features actors Diego and Isabella, indicating that he has a director-actor relationship with both of them for that specific production. Maria, on the other hand, is the director of the other play, which includes actors Isabella and Alejandro, showing that she has director-actor relationships with them for their respective production.

Since Pablo is the set designer for the play with Diego, and Diego is in Carlos's production, there is a director-designer relationship between Carlos and Pablo for the same play. Lucia is the set designer for Alejandro's play, which is directed by Maria, indicating a director-designer relationship between Maria and Lucia for their mutual production.

Carlos is not involved with the play that Alejandro is acting in because that play is directed by Maria. Carlos's involvement is limited to the play featuring Diego and Isabella, and there is no indication of him having a professional relationship or any involvement in Maria's production with Alejandro and Isabella.
