I have a test where I am given the following article, what is an answer for the question: What is the last name of the painter Scarpia mistrusts and believes complicit in Angelotti's escape? ?

The Sacristan mumbles his disapproval before leaving. Angelotti emerges and tells Cavaradossi, an old friend who has republican sympathies, that he is being pursued by the Chief of Police, Baron Scarpia.

Cavaradossi reassures her and Tosca tries to persuade him to take her to his villa that evening: "Non la sospiri, la nostra casetta" ("Do you not long for our little cottage"). She then expresses jealousy over the woman in the painting, whom she recognises as the Marchesa Attavanti. Cavaradossi explains the likeness; he has merely observed the Marchesa at prayer in the church. He reassures Tosca of his fidelity and asks her what eyes could be more beautiful than her own: "Qual'occhio al mondo" ("What eyes in the world"). After Tosca has left, Angelotti reappears and discusses with the painter his plan to flee disguised as a woman, using...
