This question is based on William Shakespeare's Twelfth Night. According to the play, the Duke of illyria is fascinated by

Analyze the question: It asks what Duke Orsino of Illyria is fascinated by in Twelfth Night.

Explain the concept: Orsino opens the play with the famous lines:

"If music be the food of love, play on; Give me excess of it..."

He is a lovesick romantic. He is not so much in love with Olivia herself as with the idea of being in love. His love is self-indulgent and theatrical. He luxuriates in the feeling of longing, and uses music to feed that emotion. Olivia, for her part, rejects him. Later, he shifts his affection to Viola (Cesario) once her identity is revealed, which shows how much his love depends on the romantic ideal rather than a real bond.

Step-by-step solution:

1. Option B (the food of love): "Food of love" is part of his opening line, but it is a metaphor for music. It is not what he is fundamentally fascinated by.
2. Option C (music): He does love music and calls for it in the opening scene. But music is a tool he uses to nourish his romantic feelings, not the central focus of his character. He even tires of it quickly: "Enough, no more, 'tis not so sweet now as it was before."
3. Option D (entertainment): This is too general and is not a key trait of Orsino.
4. Option A (the idea of love): This best captures his character. His whole role in the play shows a man in love with being in love, which is the theme Shakespeare uses to explore romantic infatuation.

Option C is the most tempting distractor, since music is clearly present in his opening speech. But the question asks what he is fascinated by at the deepest level, and that is love itself, with music serving as its fuel.

Exam tip: In Literature questions on a character's trait, choose the answer that reflects the character's overall role in the play, not just a detail from one scene. Remember Orsino as "in love with love."
