In the given sentences, the one that contains the subjunctive mood is: "Espero que Juan venga."
Here's why:
1. The subjunctive mood is used to express desires, doubts, recommendations, possibilities, or hypothetical situations.
2. In Spanish, when the verb in the main clause expresses hope, desire, doubt, request, recommendation, or emotion, the subordinate clause following "que" usually requires the subjunctive mood.
3. In the sentence "Espero que Juan venga," the verb "espero" (I hope) expresses a desire or hope, which triggers the use of the subjunctive mood in the subordinate clause.
4. Therefore, "Espero que Juan venga" correctly uses the subjunctive mood to convey the speaker's hope or desire that Juan will come.
Remember, the correct sentence using the subjunctive mood is: "Espero que Juan venga."
